If he's asking $7K OBO, he already knows its value; try not to play him as a fool.
I'm sure he's already taken into account the geographic location and current condition of the car, and will most-probably take $6K+.
Chances are, $6K will get you the title and a full tank of gas. The fact that you're impressed with the car's condition also indicates your own personal interest, which adds to the value factor.
