Newbie here. Thought I'd post as an FYI for anyone looking for used A6 prices.

Details:
2005 3.2Q Black/Amaretto Leather
18 in wheels/Nav/Keyless Start/
19,000 miles
Audi Certified (big selling point)
$37,995 Before tax

Previous car was an Infiniti G35, the A6 is obviously slower but has a much better interior and a solid stable feel.
I drove the new BMW 3 series, 2004 7 series, A4, and M35. The A6 was a nice combo of what I was looking for and the price was decent.

used A6 prices. Considering that your ride was 50-51k last year seems like a good price :P

Thanks All,

The dealer had 3 2006 demos to choose from all with roughly 7,000 miles. I could have had one of those for $39,000, but they had no nav, keyless start, amaretto interior. It was a tough choice but with the Audi certified warranty on the '05, I felt comfortable getting the older car with more miles and more options. Still $38 K seemed like a good deal for a demo '06.
