What problems to expect when looking at 91' c2?
 

I am going to look at one tomorrow. I hear they had some troubles? What should I be looking for aside from performing a ppi? I have better feel on older pre-73 but have not clue on the 90's model. It's got high mileage. Please help to make the right decision. All feedback greatly appreciated.

oil leaks ... with high miles I would suspect that a lot of little thing will need attention - sensors etc...

Make sure you have a good shop look at the car.

These cars tend to have rust around the windshield and door jams...
