Re: Well, you seem to have gotten one legit answer.
I really love the 98 M3 sedan. If memory serves, the automotive press hated the steering on the next generation 3s [for a few years anyhow] and called this generation 3 the best handling ever. I've driven my boss' 97 M3 coupe many times and love it. But the toy has to be topless.
PS, the wife loves the old Z3 m coupe, nice suggestion. If I was going to go hardtop/track car only, I'd probably go with a 944 turbo.
