I'm currently thinking about buying an SZ and transplanting the TT lump and gearbox in, but I have a couple of questions...
Firstly, how are SZ TT's regarded in terms of resale? Personally, I wouldn't careless if it was me buying (if the car was solid), but I know in certain car communities there's an air of: "Well, it isn't a genuine factory model therefore it's not worth the money.".
I have seen an SZ and frankly, it's fucking lush. It's the right colour, has been garaged it's entire life in the UK, has tasteful mods and the body doesn't have a blemish on it. Needless to say, it would be worth more to me once converted than forking out 10k for a factory TT that's in worse condition.
And, lastly: What sort of money do high grade NA's go for, nowadays?
Cheers!
