i've been driving by this Z car for about a week and it's calling to me. It's a 1983 280zx non turbo. They are asking $6900 for it. While the body is in great condition, there is a little bit of rust starting at the top of the windshied in the middle. When i opened the radiator, there was some rust in the fluid, but seemed to hold fluid. The engine compartment was fairly clean. Interior was in pretty good condition. The headliner was falling down and the T tops were definitely leaking. Then engine wouldn't push past about 3500-4k. I'm thnking it should be more around $4k. What are your thoughts?
