You don't say where you are located, but I looked at this one in Atlanta:

Its good for a parts car only. I had my indy check it, one bad cylender. Body was at best ok, all windows and sunroof worked. Trunk leaked. Could be a doaner for a door or corner panel.

Owner now knows the problems with the engine.
