Ohhh, I get it, I'm a bit stupid.

What if the seller is the douche-bag, and after the PPI he says he isn't selling the car? What if he gets a better offer while the PPI is going on? What if the compression is crap on one cylinder and he won't adjust his price? What if the PPI is flawless and he realizes he under-priced the car? Now he has a PPI that you paid for and a new selling price. What if he has two buyers,and the second buyer says he'll pay $500 more if the car has a PPI? I guess the first buyer who paid for the PPI is out of luck?

I know it's unlikely, but that world (eBay) is full of unscrupulous people. If he screws me over, then yes the PPI is mine mine mine. If he is amicable and fair, but you can't agree on a price, then by all means give him the PPI. But, I would not leave myself in the position where I am obliged to give him the PPI results regardless of the outcome.
