I am looking to trade my RX8 for a RS4. One of the cars i looked at had 92000 miles on it. What i am wondering is what are some of the possible problems i might encounter with a high mileage audi or what are some of the problem i might have once i break the 100,000 mile mark? The car in question is a 2001 RS4 that looks to be in good condition and well maintained.I have yet to do a carfax check, dont want to spend the money until i get more info. The seller is asking $14,600. Good Buy?
