Not sure how well this person took care of this little baby. The cladding should clean up if you scrub it then put on a coat of protectant. That would help with the scratches also.
It needs new tires.
YOU need to go through it with a fine toothed comb to make sure for yourself that you want to but it. Try and find a mechanic in the area and take it there for the mechanicals. It looks dirty and pretty uncared for, I would be wary unless they (the Mechanic) gives you the go. Of course, I'm kind of anal so opinions may differ.
