Replying to: 213xlrv (Sep 12, 2006 10:21 pm) What I find interesting is that the SL won this latest round based on how it performed and drove, no one at C&D mentioned status and prestige as the thing that put the SL over. Now MT did mention status and what not as icing on the cake. It isn't MB's fault that Cadillac ruined their image with so many years of lame cars. One minute when the mags praise the XLR in a single car test they're all knowing and really on the money, but when they compare it and find it lacking they're clueless. Oldest about-face in the book. Plainly, I'll say it again: Between the Mercedes SL-XXX variants and the XLR-v, Cadillac has built and offers the better car. Only in your mind. Cadillac apparently hasn't built or offers squat better than MB, BMW or Jaguar for that matter. M

Replying to: merc1 (Sep 12, 2006 10:50 pm) Never did I say that the XLR-v is a sports car. If I wanted a sports car, I would have bought a Z06. Still might add one. I said the V is a sporting GT and it is the leader in architecture, design and agility in its class, not least because it is designed to avoid the useless bulk of the SL. What the magazines have to say about relative agility is irrelevant to me. I have mountains to drive in and have driven both. The XLR-v is the more agile car and easily feels by far the lighter of the two. MT and CD are just wrong, but they may write what they wish. If you look at my posts, I wrote repeatedly that the XLR-v is a sporting retractable hardtop GT. My position is entirely consistent. You're misrepresenting the facts. NO ONE will feel they must go to the aftermarket for brakes for an XLR-v. But just as Mercedes, BMW, Lexus, Audi, Ford and others have cars that support rich aftermarkets, options exist for the V too on many fronts, owing to its Corvette architecture. Do you need aftermarket brakes for the V? Not in the least. Can you get some monster brakes that will harshen the ride and boost chance that lesser cars rear-end you? Absolutely. Buyer's choice. The car is perfectly balanced stock. The biggest improvement one can make to any car using run-flat tires is to migrate to a stickier conventional inflatable in the high performance Z or W class. It's easy to do and if I wanted to discreetly and seriously affect the reviewers' perceptions of the V, that's the change I'd make. But in real world driving, the Pirelli Eufori on the car is excellent and the security is well worth the current cost in that technology to ultimate grip and ride. At a quarter ton heavier, comparing the SL to a beached whale is an insult to the whale. It's 500 pounds of lack of engineering imagination any way you cut it. The SL55 has torque, in the way that the 5.7L pushrod Chevy small block had a twist advantage over the 4.6L OHC Mustang mod motor. But it feels like even more of a pig than the SL550. It gets out of its way maintains traction, but the pendulum of that quarter ton degrades everything about the experience in motion. In 8 or 10 years when MB finally re-architects the car, maybe they'll come up with a modern lightweight structure. Nah....maybe not. You're bench comparing the opinions of magazines that are packed with as much bias as you'll find on any internet board. I've actually driven the cars. When you do, you can come back and talk about winning or losing comparos. I'm in a position to say, and my verdict is XLR-v leads this class of car. And yes, it is the most sports-car like of the category, which is one of the reasons it wins for me. Phil

Replying to: merc1 (Sep 12, 2006 11:04 pm) They might still say, "The MB SL is wildly overweight in its class but we like it anyway." Then I can say it's an honest review and the writer's priorities are woefully misordered. Anyway, no I did not ever think magazine reviewers of any employ were worthy of influencing my perception of a vehicle. And yes, the current SL is antediluvian with respect to its designers' nonchalance about useless mass. I wouldn't want to be associated such lack of progress. Phil

Replying to: 213xlrv (Sep 12, 2006 11:15 pm) Again the same ole same ole, and yet this advantage hasn't shown up anywhere. Why is that? It doesn't exists because someone at GM didn't take advantage of it. Ok you say the mags are wrong I could respect that if, and only if you hadn't praised them before when the tested the XLR by itself and found it to be a good car. Now just because they didn't put it ahead of the SL or any other car in the class, now they're just wrong. You can't have it both ways. If you look at my posts, I wrote repeatedly that the XLR-v is a sporting retractable hardtop GT. My position is entirely consistent. You're misrepresenting the facts. Actually you are because for the fact that XLR weighs less hasn't turned up any advantage in handling. You're the one trying to turn a slight weight advantage into something heaven sent and it has proven to be anything but that. At a quarter ton heavier, comparing the SL to a beached whale is an insult to the whale. It's 500 pounds of lack of engineering imagination any way you cut it. Wrong again, the exact weight difference is 380lbs, not a 1/2 ton, yet another inaccuracy you've given here and to say that SL has a lack of engineering imagination is really ridiculous. The SL has more featurs than the XLR to begin with such a a pop-up roll over protection system that adds weight and yet they've managed to "engineer" it to handle better than the lighter, gussied up Corvette known as the XLR. Imagine that. You're bench comparing the opinions of magazines that are packed with as much bias as you'll find on any internet board. I've actually driven the cars. When you do, you can come back and talk about winning or losing comparos. I'm in a position to say, and my verdict is XLR-v leads this class of car. And yes, it is the most sports-car like of the category, which is one of the reasons it wins for me. Sure and until then keep thinking that you're found something superior when the industry experts are saying otherwise and as far as C&D goes they didn't even think enough of the XLR-V, a 100K top of the line Cadillac to put it over BMW or Jaguar either, so Mercedes is about the least of your worries. Cadillac ain't superior, heck they ain't even at the front of the class. They're bringing up the rear as most GM cars do. The only reason I find most of what you say to be bunk is because you think that the XLR is superior in every way and there is no car in this class that is superior in every possible way over the competition, such a notion is absurd and this bs about weight and what not is really special because it hasn't turned up anywhere. If what you say were true wouldn't someone else agree with you about it? The mags can't be smart and all-knowing one minute, but they next they're cluess. M

Replying to: 213xlrv (Sep 12, 2006 11:28 pm) Put aside who won what for a moment and just look at what is being said about the handling between the two cars. Your weight advantage theory just hasn't held water. Sure the SL is heavier and could stand to be lighter, but if you can't see the effort that MB put into making the car drive smaller than it really is then there is no point it talking to me about how light a Cadillac is either. The SL's weight has been dealt with using their ABC active suspension and they've done a superior job at it. Now as to what feels more agile that is arguable for sure, but this nonsense about the SL not beng able to handle or that is someone this poor handler and the Cadillac is so much better is just plain BS, regardless as to which car won the overall comparo. All the while you seem to have forgotten that this class of car isn't decided upon by dynamics like sports cars are, that is why even if the XLR were a superior handler (which it isn't) it still wouldn't top the SL. The XLR is cheaply made and doesn't come anywhere near feeling like a 100K car. M

Replying to: merc1 (Sep 12, 2006 11:41 pm) The GM active suspension is at least the equal of MB's, so no points for DCX, especially since the GM method is simpler, lighter and more elegant from an engineering point of view. I never said the MB doesn't handle or can't put up the numbers. I said the experience is degraded by the weight and that ruins the kinetics from the driver's perspective, relative to the Caddy. Yes, the SL keeps the tires planted. No, it doesn't feel as composed doing it. The only small definciency that Caddy V has experientially is the very slight sideways bump in a potholed or bumpy curve, which is a characteristic of every Corvette with a transverse-glass-leaf suspension. I kinda like it. Feels fun and doesn't actually disturb the car's stability. I'll take that over a car you can feel fighting to manage its own mass. This class of car is certainly a sporting class of cars and dynamics in motion are among the criteria for success. Certainly very high for me and others who own the V. If I only cared about cruising, there are Buicks to buy along with the myriad Mercedes choices. How about a Buick with a V8? As I said, I am still waiting for this allegation of cheap build to evidence itself in my V. Relative to everything else that costs $100K, the V feels like a hundred Large to me. The Jag XKR doesn't handle well enough for $100K. The Aston V8 Vantage isn't quick enough for its price. The Mercedes SL feels too ponderous and pretentious. The wonderful Maserati Grand Sport's clunky transmission undermines its price with every shift. Uh...let's see.....the XLR-v has leather, wood and plastic inside just like everything else put to shame by the Italians. And none of it seems to be wearing in the slightest. It runs in the 4s right out of the box. stops and turns on a dime. Stone cold reliable. Gets as much attention as any car I see here in L.A. at any price. Comfortable. Sports car dynamics. But the plastic surrounding the nav screen and a few buttons come up short in some people's eyes? Hmmm....in a world where every competing car is imperfect in a meaningful way, I think I can hack the 6 square inches of untextured plastic and enjoy my car while Cadillac revises the cabin on v2.0.

Replying to: merc1 (Sep 12, 2006 11:33 pm) Didn't I cover the mags? I'll cite them for people who seem to respect them. I won't for people who don't use them as "evidence." I've explained how a writer gets my respect and attention, and it isn't the conclusion but how they get to it and whether they are holistically evaluating the car in question. I also never said the XLR-v is "superior in every way." I've said it is on balance the best car of its car in its class. Nobody in the class has a perfect polar graph of selection attributes. The Maserati has easily the most beautiful interior in the class, the loveliest paint, and it has a fab naturally-aspriated Ferrari-derived engine (my preference over supercharging), but it also has a cloth top, a clunky tranny, a strange driving position, and spotty service distribution. I almost bought one. The Jag and Aston have the second best leather in the class, lightweight aluminum structures, and rich British interiors but both are down on power, handling is too soft, and structural rigidity on convertibles (which are cloth tops) trails the Cadillac. The Lexus loses in every respect. There isn't a single redeeming aspect of the car I'd prefer over the XLR-v. The Mercedes SL55 has more displacement and a large torque advantage set in a dated but torsionally-stiff architecture with long overhangs, short wheelbase, and a quarter ton of excess weight that reflects a lack of design imagination. Interior materials are high quality. Interior design is overwrought and functions are obscured by poor ergonomics. Its suspension technology is the only one in the class to approach GM's in efficacy. The Mercedes is monstrously overpriced and is common as dirt where I live. The SL550 shares the traits of the 55 AMG, but sheds some ponderous weight though it is not engineered to drive as sharply as the AMG. Both have a nice transmission. On balance, the V's only area of real, common, criticism relative to the class is the interior. I don't agree it is meaningfully deficient, and I am here to tell you it works and wears just fine, and makes the right impression on people who get in the car. Let Maserati loose on the V interior, and all the carping about the car would go away in a flash. The V's interior ain't a reason not to choose the car now, however. No doubt the next version will be better still. And by the way, other people do agree with me. The XLR/XLRv owner boards are full of people who bought the car for the same reasons I did, after having owned MB, Lexus, Jag, et al. And most of them never owned a Cadillac before, many never having previously owned an American car, either Phil |

Replying to: 213xlrv (Sep 13, 2006 12:06 am) Well that is IYO, and it doesn't give the XLR any advantage in handling either. If this was true, that suspension combined with the weight savings should enable the XLR-V to run rings around the competition and it doesn't. Period. No points for GM and the handling advantage still winds up on the competitor's car. I never said the MB doesn't handle or can't put up the numbers. I said the experience is degraded by the weight and that ruins the kinetics from the driver's perspective, relative to the Caddy. Yes, the SL keeps the tires planted. No, it doesn't feel as composed doing it. The only small definciency that Caddy V has experientially is the very slight sideways bump in a potholed or bumpy curve, which is a characteristic of every Corvette with a transverse-glass-leaf suspension. I kinda like it. Feels fun and doesn't actually disturb the car's stability. I'll take that over a car you can feel fighting to manage its own mass. And what I'm telling you is that no one has found anything to support this advantage you keep talking about. These are professional drivers who have been testing cars for years and they all say the same thing regarding the handling of the SL and the XLR, one is good and the other is better, the latter being the SL. This nonsense about how the XLR feels and what not isn't enough to put it over the SL and the others in this class because the rest of the car is lacking. This class of car is certainly a sporting class of cars and dynamics in motion are among the criteria for success. Certainly very high for me and others who own the V. If I only cared about cruising, there are Buicks to buy along with the myriad Mercedes choices. How about a Buick with a V8? Here we go again, you're missing the point. Of course dynamics are a point of reference in this class, but the XLR falls down on its face in other areas which you'll all of sudden dismiss. The feel of the materials, design and quality of the XLR/V say cheap GM car, not 100K blueblood. That is why the XLR-V could have the best handling in the world and still come up short, heck it already outrun the SL550, 650i, and XK yet that didn't carry as much weight as the details, which is where GM is clueless still. As I said, I am still waiting for this allegation of cheap build to evidence itself in my V. Relative to everything else that costs $100K, the V feels like a hundred Large to me. The Jag XKR doesn't handle well enough for $100K. The Aston V8 Vantage isn't quick enough for its price. The Mercedes SL feels too ponderous and pretentious. The wonderful Maserati Grand Sport's clunky transmission undermines its price with every shift. Uh...let's see.....the XLR-v has leather, wood and plastic inside just like everything else put to shame by the Italians. And none of it seems to be wearing in the slightest. It runs in the 4s right out of the box. stops and turns on a dime. Stone cold reliable. Gets as much attention as any car I see here in L.A. at any price. Comfortable. Sports car dynamics.

Hmmm....in a world where every competing car is imperfect in a meaningful way, I think I can hack the 6 square inches of untextured plastic and enjoy my car while Cadillac revises the cabin on v2.0. Yeah let me guess, every other car has flaws except the XLR? Right? You kill me with all this about other cars yet you can't see the glaring cheapness of the XLR's interior. Driving the car for 8K miles doesn't prove anything IMO, any 100K can stand up to 8K miles of use. You've got to be kidding if you think that 8K is some type of milestone that proves quality! Now wait a minute, you've driven the XKR to know that it doesn't handle well enough for 100K or are you going by something you've read? I honestly feel for you if you think a XLR feels like a 100K car. M

Replying to: 213xlrv (Sep 13, 2006 12:36 am) Yet the SL gets the nod in handling. Go figure. Either someone is harping about nothing or the entire industry doesn't know what they're talking about. The Lexus loses in every respect. There isn't a single redeeming aspect of the car I'd prefer over the XLR-v. The only thing we agree on! The SC430 is for the pinky-ring set. I also never said the XLR-v is "superior in every way." I've said it is on balance the best car of its car in its class. Nobody in the class has a perfect polar graph of selection attributes. Your last sentence contradicts the first one. The XLR-V isn't even close to being the best car in this class, as it can't even beat a base SL550. The Mercedes SL55 has more displacement and a large torque advantage set in a dated but torsionally-stiff architecture with long overhangs, short wheelbase, and a quarter ton of excess weight that reflects a lack of design imagination. Interior materials are high quality. Interior design is overwrought and functions are obscured by poor ergonomics. Its suspension technology is the only one in the class to approach GM's in efficacy. The Mercedes is monstrously overpriced and is common as dirt where I live. Gotta love personal opinon on design passed off as some type of flaw. Just say you don't like the SL and this would make sense. Again your cited weight advantage hasn't proven squat in handling prowess in favor of the XLR. Gotta love the "common as dirt" comment too, i.e. Cadillac doesn't and can't sell anywhere near as many XLRs so I'll knock the Benz for being a commercial success. I love it when people who champion slow selling cars try to hint or imply that they are somehow more exclusive when the truth of the matter is the car in question is 10 or 10 times a sales dud! Exclusive is when you can sell more, but won't or when you only build a set number and that is it. GM could crank out XLRs all day long if the market warranted, but it doesn't so please spare me the hint or implication that the XLR is somehow exclusive when the reality of the matter is very few people want or would even consider a 75-100K Cadillac. The Caddy name doesn't warrant or carry nearly enough clout to sell a 100K car in any real numbers today. The V's interior ain't a reason not to choose the car now, however. No doubt the next version will be better still. IYO. Wait till next year or next time, a classic GM defense. GM never delivers a complete car, it is always wait until next time, which by then the competition will have moved the goal post. And by the way, other people do agree with me. The XLR/XLRv owner boards are full of people who bought the car for the same reasons I did, after having owned MB, Lexus, Jag, et al. And most of them never owned a Cadillac before, many never having previously owned an American car, either Seeing as how they sunk 75-100K into a market lagging American car they literally have no choice but to tell themselves this, otherwise they'd have the worst case of cognitive dissonance in the recorded history.
