Hi. I was thinking about purchasing a 1995 850 T5-R for around $13,000. It has

41,000 miles. The "check engine" is on, and the owner told me that it is the o2

sensor. He told me that he would have it fixed if I decided to purchase the car.

I also noticed that when I took it for a test drive that when I made a left turn

, a could hear a clicking noise coming from the left tire area. The owner told

me that it is normal when you make a deep turn. I was wondering if it could have

something to do with the cv joints, or axle? The car also has a few scratches

and some of the paint is oxidized. What do you think about all this? Is it a

fair price? What other problems could cause the "check engine" light to come on?

All comments are greatly appreciated.
