Just because a car makes a louder noise than a gti does not make it at all infantile. Besides I'd just like to clarify the GTI is the car I wanted. The Car I got, it's interior quality was a big issue for me because I am going to spend a lot of time in there.
I'm not saying I want an St in anyway I just want to increase the noise level slightly. The R is perfectly grown up too, but it makes more noise than the GTI
