Crossfires are sexy...except for that ends-too-fast back end. The roadster looks better in that respect...since it actually has a bit of a back end...and the SRT6's spoiler seems to offset that styling flaw.
Rear visibility is garbage though, plus it's sort short on interior space...and mechanically, it's a pretty old car. It's a Mercedes underneath though...so it'll be pretty solid.
If you like it though, go for it. It's quite a nice car.
If not...go for the 3-series or TSX. They'll be more practical, and they're both still solid, stylish cars.
