on old cars i now think the body work is the main priority, as its the most expensive to sort. if you don't feel confident, walk away. there are tons of gti's out there and a bit of searching will get you the right one. if you're doubting it now it could be one of those things that always annoys you about the car. at the end of the day that one doesn't look the best gti out there and unless you really really want a 5 door, white, f reg, small bumpered, corroded teardrop wheeled gti, then i'd keep looking for one you have confidence in!
