All I would say is don't buy a car even with just a little rust if you are not prepared to repair more. I've been welding a car I bought cheap and I thought the rust was superficial, turns out it wasn't! That was supposed to be galvanised too!
Haven't a clue value wise, perhaps an MR2 forum would be a good call.
really like the look of your project!
im prepared for more rust than I can see in the pictures, I think what I meant by the rust comment earlier is ... that it 'doesn't need immediate attention' if that makes sense haha, i'm just really hoping it doesn't turn out to have loads of 'bodged' repairs like my soon to be abandoned mini... at this rate.
pls excuse me if what I'm saying doesn't make sense, pretty tired haha.
can't multi-quote on mobile, ballache.
