I have an A6 for past couple of years. When I first saw it, I loved its interior. No comparison with the BMW or the Mercedese. The car drives smooth, has a wonderful handling, and as a driver one does feel driving a really a high-end car. But as the saying goes, you pay what you get. When it comes to regular maintenance, oil changes, etc Audi (and other European cars) can and will hole your pocket (unless, money is not an issue here ). The labor cost, the parts, and anything else with Audi is an expensive deal. You can buy the extra warranty, but these generally covers electrical and mechanical problems, and not your regular maintenance. Go for a Japanese ( or Korean) ..you be better off. Hope this helps.
