1994 Volvo 850 Turbo Wagon. 1 owner, 87k miles. No maitenance records. New tires, includes two sets of wheels. $7799

I went to test drive the car, and here are the issues I had:

(1) After a few spirited runs, I turned the car off and checked the oil dipstick. The oil looked fine, but when I pulled it out, there was a little steam or smoke coming out of the dipstick hole. When I questioned the owner/salesman he said that because its a turboed engine, and because I probably just made a few "spirited" run, the engine operates at a higher temperature and pressure so the steam/smoke is normal. I asked my mechanic friend about it and he said its normal. I've never seen it before though. Your thoughts?

(2) The left rear power window would not go down (the switch wouldnt work Im assuming). Owner/salesman said he would see what he can do about it.

(3) The car comes with new tires, so I don't know if this has anything to do with it, but when I would turn the wheel all the way to the left or right, the tires were rubbing the fender. Just barely, but enough to make some rubber strips stay on the fender.

(4) He said he could sell me a 3-year, 54,000 mile warranty with a $100 deductible that covers: powertrain/drivetrain, steering components, brake components, power window motors, seat motors, etc. for $900... national coverage as well. Good deal?

If he is able to fix the window, figure out what is wrong with tires, and if its true that the dipstick hole steaming is no problem, I think I'll offer him $7,500 for the car and the 3-year warranty. (He has the car listed at $7799 w/ a 3 month warranty).
