Im lookin at buying and 85 gts with over 200k. im lookin for a solid beater that is dependable, this car is a ONE OWNER car, and the guy took excellent car of this car, the floor mats are perfect, not dent on the entire car, and runs great. Im goin to do a compression test on it this weekend, what numbers in that compression test I should look for.

Is there anything else i should look at, this a northeastern car and has been driven in the winter.

I looked at the engine, and there appears to be an oil leak in the front of the valve cover is this common. Are there any other common problems with these cars?

I think it's something like 9.7:1
