I'd give the guy serious $hit about wasting my time, and the fact that once he bought it, it was HIS problem, and that he should have gotten a PPI.
I'd flat out tell him not to waste anyone else's time - if he plans to buy another one, get it checked BEFORE he agrees to buy it.
Aside from that, if it were me, I'd tell him tough ****************. If I got that much money for my car, I'd tell him I'd go half on the RMS and strut, and THAT'S IT. AND that he'd be LUCKY I was doing that. CAVEAT EMPTOR!!
