For a 2001 Audi A6 Station wagon with 74k miles, I get widely differing prices:
Edmunds: 10,300
NADA: 12,700
What’s the deal?
ALL price guides are ESTIMATES. There is no “hard and fast” price for a given car. You vehicle is worth what someone is willing to pay for it, and nothing more.
If you are a potential buyer, a given vehicle is worth what you, or someone else, is willing to pay for it. Price guides are estimates, that’s all.
I just re-read your post. I wouldn’t pay EITHER price for this vehicle. It’s SIX years old, and it’s an AUDI, meaning it will soon cost a small fortune in repairs. Perhaps you should forget the word “small.”
Don’t walk, RUN away from this vehicle. If you buy it you will be sorry. Maybe not today, or next week, but within a few months you will be sorry.
If you can’t afford a new Audi, you can’t afford a used Audi. Same goes for Volvo, Saab, Mercedes Benz, Porsche, Jaguar, Land Rover, Volkswagen (yes, VW), and any other Euro-brand you can think of.
The A6 Avant is a beautiful car, no question about it. I wish I could afford to drive one, but I can’t, and I’ll bet you can’t, either.
Interestingly enough I know a VP of a major insurance provider who buy Audi’s in the 100k-150k mileage range at about 7 years old. He typically drives them for 50k-150k more without serious repairs. He has a great and relatively inexpensive import mechanic at his disposal. He has great luck and he commutes ~25k miles/year.

The deal for me is that you didn’t give me enough information to comment. What options are on the car? What is the condition? Is this a dealer or private party sale? Without this information, I can’t comment, except to say they prices are different, and that’s no help.
