Ive had Audis for about 20 years now and my last one was an A6 Avant. I am hooked on wagons because of thier style and utility (great for Michigan outdoorsmen). Unfortunately my last one died and now Im trying to chose between a 2002 S6 (95k), a 2004 Allroad 4.2 (75k) and a 2004 Allroad 2.7 (75k). Which car would cause me the least headaches in terms of repair. I have some mechanical aptitude (have changed shocks and heater cores) So I can do some work myself. I just dont want to spend $15k on a nightmare. Any suggestions on which to chose?
