Any other suggestions? It's a bit strange that nobody has mentioned the 350Z or the RX-8, the two cars I've thought about the most.
The BMW 330Ci is nice, but it seems marginal in the HP : Weight ratio. From a performance perspective only, I never thought it was much more than 1 step (maybe 2) better than my 6 - with the edge going to it because of balance and RWD. Is it really comptetive in its class? Same story with the IS300. I very much like both these cars, so don't think I'm disrespecting them.
I never would've considered a muscle car like the Mustang until the first event of the year in Brooksville. That guy with the gold 98 Camaro showed what a good driver can do with American power - and presumably some good tires!
What do you think about the 350Z and RX-8?
