If you just want to run a 328 as it is then go ahead, you can get a cheap car. But what i'm trying to get across is that if you want a 330 sport but in a cheaper way, buying a 328 and making it into a 330 is going to cost you MORE
If you want a sport looking version but a 328 body then it wont really cost that much more unless you buy brand new parts and are young in a crap post code and bad history with your insurance / license.
