My 2003 A6 lease is expiring shortly and i have 46000 miles on it. Audi is giving $3000 incentive to buy back. The car has been pretty good except for some minor annoying troubles that i had to go to the dealer and drive a loaner collora like car. I love the way the car drives and thinking of buying it. I would like feed back about any issues with the 2003 A6 model and your opinion about the back at $16000.
