The only problem with the before the fact PPI is that most PPIs are 90% verbal. My PPI was 2 hours with the mechanic going over every square inch of the car. I felt like I knew the car intimately afterwards. Will some mechanics sit down afterwards and spend 20 minutes writing up something more substantial for potential buyers to read?

Depending on how much the car is worth it may be worth having a full service done on the car plus a compression/leakdown test and then have the mechanic document that on the service writeup and maybe an indication that no broken head studs were found during the valve adjustment. I think this kind of service/documentation would add value back to the car and result in a faster sale at a higher price.
