The rebuild costs would way outway the value once done. It's one of those cars that you restore because you want to, not to make a profit.

There's one around my way that an old boy owns. The paint is ropey as fuck, but it's mechanically mint. The guy drives it hard to, I'm always seeing it being chucked around the lanes!

EDIT\; Just found this. If this is £6k worth 'your' one has to be nearer 10k surely?
