991 Turbo PPI, What to look for?

[Hi_Fi_Guy]

A friend is going to look at a 2014 Turbo S this weekend. He plans to have a Porsche shop perform a PPI. What level of PPI should he request and what common failure points or issues should he be looking for?

I’m well versed in older air cooled Porsches as well as 986-987 era Boxster and Cayman models but I know very little about 991 era cars and nothing about the Turbo models. Appreciate any advice on typical areas to be aware of.

Car has ceramic brakes. Is there a way to check the remaining life of rotors on these?

Also, local Porsche dealer quoted approximately $2k for 60,000 miles service for 991 Turbo S. Does that sound about right or not? Not sure how much more involved the services are on a Turbo compared with a base or S model.
