I have a WRX and love it to death, nothing better then when the turbo kicks in. I've had zero problems with it thus far and have done most of the maintence myself with ease. I've heard of some problems with audi's, but i'm not sure speciffically what they are...that said they and nice cars and lean more to luxury side of the scale. If any problems with the audi do pop up they will most likey be very expensive to fix.
