I vote for the Audi, especially IF you're getting the 1.8t. Holy crap, do you know how many mods there are for that Motor? Whew!
There's a guy in the sfbavw.com gruppe, that has a 2k Jetta with the 1.8t.
Without touching the internals of the motor, he has
260 Horsepower at 16psi &
330 Horsepower at 21psi.
But the Audi!
