it looks like it could just be a very good ringer probabally done in the early 90s and lasted the test of time, everything about it is 90 spec, shell, doors, interior, rear panel etc etc. check where the chassis number is stamped on the bulk head and for damage on the vin tag esp around the rivets if anything there looks not right then you might have a problem. i wouldn't worry about it though it looks tidy and i would give you £1300 for it all day long if i was looking for one
