Let's get real please.
My tongue was only partially in cheek. I have never lost a "speed contest" by underestimating the driving ability of the typical US vehicle operator("driver" being to generous a term). At CCA drivers schools I've seen stock a E30 M3 nearly lap an E39 M5. I've also seen an E36 325i give a C5 Corvette fits. I once ran off and hid from a Subie WRX on a rainy two lane, and I was at the wheel of a 1993 Pathfinder SE(the shocks were set to "Sport" however). Mike Valentine once told me that at most schools there may a 5-10 second per lap difference between the cars, but there will be a 25-30 second gap between the drivers. A fast car doesnt make you a fast driver. I'd be willing to bet that fedlawman and his real M3 would slice and dice 99% of the owners on this board even if they were driving a new M Coupe. I always suggest that serious BMW owners attend a bunch of CCA schools so that their driving skills will not be overmatched by their car.

Well said and agree drivers need to get serious by training first. These cars are extremely capable..in the right hands.
I would not take your bet regarding "The Fed". I also wouldn't bet on 99.9% of the Wrangler owner against you in yours!

"I once ran off and hid from a Subie WRX on a rainy two lane, and I was at the wheel of a 1993 Pathfinder SE(the shocks were set to "Sport" however)".
As a well seasoned big city emergency medicine physician, I would like to make a simple plea. Please try not to kill my wife and children while performing your "validate my manhood" antics on public roads. Keep it on the track.
As an aside, currently debating the upcoming M3 vs C63 AMG vs S5. I drove the 335xi and found it to be very intriguing, but am jonesing for a bit more hp. What are your thoughts?

If you follow the BMW forums, the general consensus is that the sedans are much stiffer than the coupes, and this applies to both the E36 and E46 models..
Like shipo, I have no empirical evidence to back this up, but those who track the cars attribute it to the presence of the B-pillar in the sedans. They also say that fold-down rear seats lead to more flex, as they remove some of the bracing behind the back seats. I believe these are standard on the coupe, but optional on the sedans.
So, there you have it. I don't know that the reasoning applies to other makes, but the guys that should know swear by it.

What you just wrote dove-tails exactly with what I've read elsewhere. A combination of a "B" pillar and the extra bracing behind the rear seatback contribute to a stiffer sedan, or so I've read. To be sure I have no horse in this race, and only want to know for curiosities sake. I wonder how we get a definitive answer.

Well, in that particular case I don't believe I ever exceeded 50 mph, and I know that I never crossed the center line; Soob Man was so inept that he slowed to almost a walking pace at every corner(I guess an abject fear of lateral acceleration will do that to you). Anyway, when I drive on the street you could hardly call me a hooligan- I stay in my lane and I keep my speed within within 5-10 mph of the posted limit(although I will admit that I pretty much ignore the "Advisory Speeds" posted at corners and entrance ramps). You won't find me engaging in any full-tilt opposite lock craziness either. Just like when I'm on my Speed Triple, I ride my own ride. The same holds true when I'm behind the wheel of a car. Whether I'm on two wheels or four I don't allow other riders or drivers to coerce me to ride or drive outside my own personal comfort or safety zone. That said, if some anonymous fool behind me doesn't share that philosophy, that's his/her problem.

I haven't driven a 335xi, but I've accumulated quite a bit of seat time in the 335i. In my opinion, the power is ample but the weight of the car dulls the handling to the point that it feels more like an E39 5er- to me, anyway. While that's certainly no bad thing, it just doesn't have the direct feel of the E46 3er. As for generating more HP, it's simply a matter of cranking up the boost- and there are already several vendors marketing devices/software that do exactly that. The problem is, there's no free lunch; more boost and more hp will generate more heat- and the 335i cooling system is pretty marginal in stock form. I've considered picking up a 135i in a year or so, but I think I'd probably be happier with an E46 M3 with the Competition Package. Having said all that, if BMW NA decides to import the M5 wagon all bets are off...

"Does anyone find any difference (other than the price) between 91 and 93 octane in the twin-turbo 335 engine?"
Regarding octane, remember that while the knock sensor will prevent detonation with lower octane fuel, you get no benefit from using fuel rated higher than specified. If BMW recommends 91 octane for optimum performance, using 93 or 100 octane won't result in added performance or economy.
"fedlawman and his real M3 would slice and dice 99% of the owners on this board even if they were driving a new M Coupe."
I feel pretty confident about the Wrangler, but an M Coupe I'm not so sure...

Agreed, although in my area the only fuel grades are 87, 89, and 93 octane. These are the "Yellow Label" or AKI numbers, which are an average of the research octane number and the motor octane number. Since BMW usually refers to the AKI rating in their newer owners manuals, that means that 93 is the proper choice for me.

Here's a nice video of a real M3 thrashing around the Isle of Man -- the only place I know of with no speed limit on rural non-freeway roads (now that the Australia's Northern Territories has adopted 130 kph as of Jan 1).
