I have "looked at" no less than 7 cars for both FGF asnd PY-type "friends." I do so because I like to help out. In about half the cases I have advised the potential new owner to walk away. In most of the other half I have advised that the price is fair for what they are looking for and looking at.
I have never expected, and never been compensated for, my time and "expertise." (A profession a$$.hole is quite expensive.) What I have been able to do, however, is to save a few poeple I don't know untold time and money investing is a car that I belive is beyond reasonable expecatation.
Unlerss you have an understanding or contract established ahead of time, expect nothing and be happy if that is what you get.
