My Dad's Audi A5. Full S5 interior and exterior, StaSis full exhaust system, BBS CX-R wheels, H and R wheel spacers and lowering kit, black window tint.
Soon to come: Aftermarket turbo, Brembo brake kit and aftermarket chip (when the 2011 software comes out)
Yeah it is! My Dad decided on the A5 over the S5 or the RS5 because the A5 was $20,000 cheaper than the S5, but you can get the A5 to have much more power for less than 20 grand. A client of my Dad's specializes in tuning the A5's, and right now we're working on a custom intake and chip for it, which should g4et in in the 320hp range.
have fun...
