the most important thing is buying a cheap, durable car. If you rally or rallyX it, yuo're gonna crash. no point in getting something you'll hate yourself for crashing. Also look at class divisions. most go by displacement, and other items, such as turbos. Up here in Canada, anything over 2.0L will put you in open class, against EVos and STIs. Golfs are competative. this years national P3 champ was in a MkII GTI. Also, suzuki swift twincams do well, and are stupid light. learn how to left foot brake, and you should be able to hustle around a FWD car as fast or faster than a RWD car. The biggest thing is seat time. you could buy something fast, but if you can't drive, you won't be competative. Get something underpowered that forces you to keep speed through turns, and hold onto momentum. And stay away from AWD. just think about other cars in teh stock class (WRX, STI etc)
