You guys dont have to do this but if an issue comes up within the first 30 days of new ownership, you might keep a couple hundred for a good faith deposit on a repair.
I think if the guy buys the car sight unseen and doesnt get a PPI then its just goodwill on your part.
You dont have to, but I did. But I didnt think about it till after it happened and I felt guilty about it so I paid for part of the repair that happened right after he got it. I told my buyer it was mechanically sound, and it had a problem.
You dont have to no one will ever know.

I did the same thing once. I sold a car (not a Pcar) that had unknown problems I knew nothing about. After a brief and very civilized discussion with the buyer and we agreed to split the repair cost. Do unto others...

Minne was on autotrader when the guy in France picked up on it. I did not advertise anywhere else. He was very knowledgable and asked all of the correct questions. He said that he was buying for his girlfriend, but his email was porschemotors@gmail.com......so I think he is reselling - no matter to me though, full price is full price
