I think the most important thing is to understand the mechanical flaws that have showed themselves to be rather universal... VC pad wear, ims failure, bore scoring are probably the top 3 serious ones, AOS failure and worn suspension bushings (especially on rear components) being more minor but still a problem. There are a lot of other issues that are not so systematic but are notoriously pains in the ass - sai issues, vacuum leaks, MAF sensor issues, convertible top transmission failures, to name a few.

Durametric will help to detect vc pad wear, ims failure is a pinata (either you hit it or you don't), and bore scoring will only be seen with a borescope or leak down testing.

In general, if I had to pick only one, a leak down test would be the one thing I would pick. There's no way you're gonna accomplish that in the guys driveway though.

The other issues will be rather evident.

If you can't do a formal ppi, run the full durametric, makes sure all the numbers check out, and then test drive the piss out of it. If the numbers check out and she feels good with the pedal on the floor and you pegged to the door in a turn, you're probably getting a good car.
