The GTI is one of the most funnest car i have had the privillage to drive. its such a quick car i cant tell you whats its like to fly from one light to another its awesome. If you have the chance to test drive one or if you know a friend that has one you can feel that it is truely a "pocket rock!"
My favorite feature is probably the tilting steering wheel and the AC controls. You can put the steering wheel any where you please and the ac controls are simple and useful.
The only thing i could suggest is the handling of the car, its good but it could be better. but then again if you want handling more than horse power then buy a 1.8t =)
