Looking at an 86 GN - what to look for?

[cuda6pak]

A friend of mine is looking to purchase an 86 GN in a few weeks. Supposedly the car is stock except an upgraded turbo, not sure on miles but I bet it's got a few. What all should he look for in terms of problem areas specific to GN's or what to check when test driving?

Thanks guys
