Interesting questions and I'm sure not the best one to answer since I just got into performance cars a couple years ago. As far as the numbers, I've seen and talked to those who think the numbers on the new Z06 are conservative, fwiw.
 
   As far as the front vs. mid or rear engine design I've read a lot about the trade-offs for each which seems to be the major issues. Porsche has perfected the rear engine design flaw and many use its advantages to get tremendous performance but for the average driver it can be a handful. The front engine has been evolved into an almost 50/50 weight package that makes the car easier to drive but can also give up something at the limits of performance which very few can explore. Mid-engine is ideal but seems not to lend itself to mass production or mass marketing.
 
   The small engine supercharger is a good solution for some applications but not likely for road racing, which is what many in sports cars like to do. The power isn't as linear according to some, I've never driven one on track, and makes the handling an issue. If all you want to do is go straight, enjoy the power. The fact that engines w/o SC's can easily get to 400 hp makes them good for road courses, anything over that is a race car and goes far faster than stock safety equipment should be pushed.
 
    About the Evo's and STI's they are good on road courses but they are really ralley cars and have a higher COG than sports cars. The AWD seems to cover up driver error until you get to the limits, again, and then when they have issues they have more rolls than what I see anything else doing on track. Although lately I've seen a few Corvette's into walls, at least they were sitting firmly on all four wheels. As to the longevity of boosted cars and work done by backyard tuners I wouldn't have a clue.
 
   I didn't get my first Vette until the kid was out of College, Good luck!

I have been reading the postings about the car with the cracked block. Terrible!!! My car has 400 miles on it, I don't drive it much. I was not leaving it in reverse when parked, but after reading these postings, I will be for sure.
 
I do have a question for all of you mechanical Vette people. I was driving up to a traffic light, slowing down, and heard a loud bang. At first I thought something had smashed up in the wheel well or I had a tire blow-out. However, I didn't hit anything, the tires were fine, BUT the stereo, etc. had gone to Driver 2 settings. I hope that the "pop" that I heard was not electrical but I'm not so sure now. I have been having a problem with the memory settings for the seats and the power telescoping wheel seems to have a mind of its own sometimes. I've been driving and the wheel would move in or out on its own.
 
I am VERY concerned about this noise that I heard. I hope that something didn't crack (like the other Z06) or break. If anyone has ANY insight, please let me know what that could have been.

Does anyone have advice on the proper shifting or an improved technique in shifting of the Z06? Seems like I am a little jerky and bumpy with it.

I'm thinking it might be hard to not jerk a 505hp car. When I drove one at Spring Mt. Motorsports Park in Pahrump, NV they had us work on heel/toe a lot since getting the rev's matched is what can make you smooth. I used to have to work to get my RPMs within about 1000 of my goal but after three years I can give a blip of the throttle that will just give me about 300 rpms when going real slow on the street. All it took was lots of practice, but after 54k miles on mine, of which just under 10k has been on track and probably almost 10k of the 20k on the wife's, it does get to be pretty natural. And I'm betting I'm not smooth compared to some of the instructors I've had, it just takes seat time.
 
BTW, heel/toe covers a lot of different techniques that include toe on the brake, heel on the gas; left side of the ball on the brake and right side of the foot on the gas with a twist of the ankle (which works better for me) since I usually drive with wide bottom shoes. There are several other variations as well. The real objective is to take the car at say 1500 rpms in 6th at freeway speeds and get it down a gear and let out the clutch with the rpms at say 2200 rpms which will exactly match the engine to the gear box, easier to understand than to get consistent. On the street if the car surges or lags a little because the match is off by a bit is usually no big deal. On the track if you are going into a high speed corner and you lock up the rear, or even drag the rear just a bit you can pass the turn in point and with no weight on the rear, so to speak, things get very unsettled. Good luck and congrats on the new Z06.

when I purchased my ZO6 i did look what options i had to purshase on line or with the dealer ship. when i figured the amount from poeple( dealer ships on line) i was paying the same amount that i would have through a local dealer ship. the resons were transportation cost , the fact that i touch and felt the car, and picked what i wanted.most dealer ships are charging 8,000 to 15,000 over msrp which is what is going to cost you if you purchased the car thrue an online dealer.

Sorry to hear about the "huge problem" someone is having with their Z06. With all the design and engineering GM poured into the car, I would have thought the General would have installed Customer Delight as standard equipment.
 
THe Z06 has been a favorite car for me since its launch, but GM's response to the person with the "huge problem" makes me rethink the purchase. You can buy a lot of other car with $80K. Heck, you can buy a lot of other carS, too.
 
Jeremy CLarkson of the British mag Top Gear is engaging and funny in this video of his test of the Z06. He actually races burning petrol. I won't tell you who won.

Not one of the numerous reviews of this car I've read have faulted it for day-to-day drivablity. Quite the reverse. They state it handles surprisingly well in traffic.
 
This guy Clarkson is apparently prone to hyperbole and self-importance, typical boob-tube boob. I trust his objectivity and expertise as much as Paris Hilton's. For example, the butterfly exhaust valves are there to keep the noise down, esp. at low speeds, not to give the sound "extra range." Also, duh, the body is soft because it's fiberglass.
 
The only useful bit of information in this piece is that the rear end has a tendency to slide when the car is pushed hard.
 
And I certainly can do without Lord Twit's Euro snobbery and anti-Americanism. The Vette a boy band wannabe? Compared to what? A Jag?

My $0.02 - Clarkson is well known for his hyperbole, but his opinions of American cars are basically justified if you consider his point of view - he's spent a lifetime driving and testing the finest European sports cars on the planet. The Corvette Z06 is a fantastic sports car, but put it next to a Maserati or Porsche, and it can come across a little crude and rough around the edges.
 
Of course, the Corvette is also less attractive overseas because, as an import, it costs a lot more to purchase in the UK (60,000 UK Pounds). That's as much as a BMW M5 or Maserati Coupe GT over there! Or maybe you are willing to sacrifice some HP for superior quality and driving dynamics? The Porsche Cayman S costs the same as the Z06 here in the US (Porsche has no problem selling them), but in the UK, the Cayman S costs a whopping 15,000 UK Pounds less than the Z06 (even the base C6 costs 7,000 UK Pounds more than the Cayman S)!
 
BTW, Clarkson bought a Ford GT40 last year, so he can't be too anti-American if he spent 126,000 pounds (about $240,000 USD!) on an American car - although he did subsequently get a refund because his car experienced continuing quality problems and abysmal repair service. Imagine that, an American car company with quality control problems and poor customer service - who'd have guessed!?!?
