I am planning to buy an 05' Audi A6 with 41,700K on the clock, the carfax shows that it was maintained every 5,000 miles at the dealership. How are the reliability issues on these cars because I have heard lots of scary stories about European cars. I just want to keep the car for 4 years and probably put 12,000k in a year, meaning I will sell it before I hit the 100k mark. Will there be any major required maintance that will be needed to take care of and how about extended warranties any recommendations?
