This is the reason when I sell a used vehicle I very clearly advise the potential buyer to get an independent PPI.

A couple have been surprised I brought it up before them.

My response has always been, "i'm not a professional mechanic, as far as I know it's sound and has no issues (other than already disclosed). If you buy it the last time I want to see or hear from you is as you are driving away. In the unlikely event there is an issue a week or month from now, take it up with your mechanic"

Surprisingly, most decline the PPI after that exchange.
