Can any one tell me if a 1998 Audi A6 Quattro has any know problems I should be worried about. I have found a great deal on this model, the ABS sensor is out so the ABS doesnt work, it has 170k miles on it, but the body is flawless and seems to drive great. Any thoughts?

 

There are the known issues with all Audis of that vintage, TB, water pump, VC/ cam seals leaking oil, front control arms. Search the forums, you'll find lots of info on these subjects. With 170K and the year you don't want to pay too much for this car. Have an indie look it over.
Good luck.

 

See if you can get maintenance records.
