I am going to look at a 1988 911 Turbo 5 speed. It's a low mileage car, and I wanted to know what to look for as far as issues go. I hope to coordinate for it to get to a local porsche Tech before I buy it.

Basic things I hope to do is a compression test and have a multi-point inspection. What do these things run for compression? Would are known issues with these cars that I should look into?

Thanks in advance.
