the new 3 series are alright. I'm not a huge fan of any of the E60+ models.
The G35 is hawt. Classy and sporty, definitely the most sophisticated choice.
350Z; not unless you want every ricer on earth trying to get a piece of you.
EVO: same as the 350Z
Fuck the X-type. Piece of low-quality american throwaway shit with a new badge. Wrap shit in aluminum foil and sell it to the queen of england as earrings, and its still shit (50 coolness points if you get the movie reference)
Audi TT: better to wait for the next generation ones; even still, current TT's have the NICEST interior design of any car on the road, but expect lackluster performance
Mercedes C230: nice benz, peppy, sporty, and generally a nice car. That said, its a shop queen. She'll be a pain in the ass and be in the shop a lot. Faulty electronics > you.
Lexus IS: Nice cars, haven't heard any complaints about them. I'd say test drive one.
