None! This car amazes me!
Car is extremely quick it can easily beat a 1994 Ford Mustang GT 5.0, and you can stay with if not beat a Porsche Boxster S while the car is stock. Trust me I have done it.
The car handles better than any I have owned to this date and is awesome even in the rain or snow. I have taken it and love to take it out on windy back roads just to see what it can do. I am pleased to state that despite my sometimes idiotic driving I have not been able to out drive the car.
I'm considering buying a WRX and from what I have heard from a lot of people including yourself, is an outstanding handling car. Is this the case??
I have a 2002 WRX. The car handles great, but has some understeer if you pull it around a hard corner. On a hard corner you need to lift the throttle and let the back of the car find its way around the bend. Or, you can just dig into the brakes a bit and feel it catch. It does have some body roll, but the car drives great. Definitely worth the $$$.
