My choices would be WRX as long as it has a good tune and not beat up transmission, A4 but the 1.8T feels a little sluggish to me in stock form, or for something different a 03-04 Corolla XRS doesn't weigh too much and comes with a 6-speed tranny and a 1.8L yamaha engine that revs to 8K rpms, the same engine as in the elise, celica gt-s, and my old MR-S. Totally a sleeper.
