I have both a 95 Dinan Supercharged M3 and a 92 NSX w/ no mod so far. I love them both (in it's own ways) With 350hp and excellent Dinan stage3 suspension the M3 can out-handle many supercars out there, including the NSX. In it's stock trim, the M3 was highly-regarded by many car magazines, especially Car and Driver. In the Sep 1997 issue, C&D named BMW M3 the Best-Handling Car for more than $30,000 (beating Ferrari F355, Porsche 911, Dodge Viper, Corvette, Supra Turbo, and even the NSX. Although the M3 (and the Supra) seemed to be a mistake in this line-up, it came out first over many cars costs twice of it's price! In the article they called the M3 the "flawless handler!" With 50/50 weight-distribution, the M3 is truely a much easier car to drive at the limit (in my opinion). When driving over it's already-high limit, the motion of the car simply transform into an easy-controllable four-wheel drift! It is obviously a much tougher task to do in an NSX. It simply takes a lot less effort to drive fast in corners (a lot less understeering and oversteering than the NSX--less drama) However, easy-to-drive wasn't the reason I bought the NSX for. The NSX is a much rare car to be seen on the streets. It has much more characters than the M3. When people buy Ferraris and Lotus's they didn't always care if they're the best-handling cars or the fastest cars, but for their prestigious name, character, looks, and other supercar factors. It's really hard to compare the NSX to the M3 simply they are both fast and handles well. Because they are totally different cars (front engine vs. mid-engine; low vs. high sitting positions; exotic materials vs....), it's like comparing apple to orange! Like I said it before, I love both car very much. If I were taking one car to a mountainous road w/ lots of turns, without a doubt my M3 has the edge here. On the other hand, on the weekend fast drive down the coastal-highway, my M3 would stay in the garage. Hope this helps!
