If the rest of the car (what we cannot see) is exceptional, then I don't see why $35k is not reasonable. However, given the fact they don't have those pictures on the website tells me it's probably not that great a car underneath. That's why the wide range.
You have to go look and take about 100-150 pics to evaluate the car. Someone can do it for you. That's what I did with my car.
Look at these 68 Firebird verts. They went for $35k-$50k (overseas buyer).
