Askmen (via the Automotive.com Car Blog) lists the five that you should be considering, if not driving, if you want to prove you're a "real" driver. They are:

Honda S2000 Roadster
Mitsubishi Eclipse GT
Nissan Skyline R34 GT-R (oh, YEAH)
Chevrolet Corvette Z06
2007 Shelby GT500

What do you think? Personally, I'm wondering what the S2000 and Eclipse are doing on the list. The former's to be gone soon and the latter needs Slimfast before even hitting the streets.  

I don’t know it may just be my bias talking but I feel s2000 definitely deserves to be on that list.  Its one of the best designed, engineered cars possibly ever.  I am actually planning on picking one up soon.

i agree, the S2000 is a motorcycle with 4 wheels and doors. I am not a honda fan by any means (far from it actually), but I would love to own an S2000. If i was in the market for a roadster, I would pick one up in a heartbeat.
