I agree... that price seems way to steep! And as a PO of one of these cars, upkeep can be very costly. If he does buy, like someone said, I would be 100% sure that the timing chains, tensioner, guides/rails have been changed recently and have a receipt of it. Also I would have the compression checked. Good luck!
