Welcome
i was in this position about a year ago and all I wanted was a faster car (I had a 1.3 escort), but I';ve come to terms with the fact that I'm gonna have to wait to get an RS

but that'll just make it all the better when I do get one
As said above its not the best idea to get a powerful car to start of with untill you know your own driving style and get a bit of experiance, because when I've had a few mishaps where if I'd been travelling faster (in a faster car) I would have proberly crashed, so its not all that bad lol
