XR2 owners, will say it's worth loads. But thats because they over estimate the value of their cars. If it needs any welding whatsoever, don't pay anything more than say, 3 or 400 quid. Becuase, if there's 'some' rust, you can bet your house that fairly soon there will be 'alot' of rust.
These cars were fun when you could buy a tidyish one for 800 quid and thrash about in it. But fuck paying 2 grand for one, as they are SHITE to drive, don't handle that well and rust quicker than a 70's Lancia...... Millions of better options out there.
BTW, I have owned alot of these cars. I await the backlash from the XR2 owners
