My daughter has grown tired of driving my 91 940GLE, and went to look at a private owner's 97 850. Outside of the owner saying car needs an O2 sensor(check engine lite on), left tire showing outside wear, and when turning tight counterclockwise, not hearing a clunk but a walawala?!! Sign of a bad CV joint? A/C compressor cycles on/off and no cold air. Could just be low gas, but is there problems with the A/C in this year? Can't shift car by stepping on brake, have to use shift lockout button. Told it's only like that in the cold weather. Is this an easy/cheap fix? Is this an interferience(sp) engine that needs a timing belt change like my 940GLE? I am going to talk to her mechanic, but would like an unbiased opinion if possible. Thanks for your assistance!!
