The median asking price for a used Audi A6 is $9,650 across 764 listings. A 2026 costs about $58,999; a 2001 about $2,988. But the same year can differ wildly: among 2003 cars the dearest asks 6.9 times what the cheapest does — condition, mileage and title do the rest.

A spread near 1.5× means the market agrees what a Audi A6 of that year is worth. Past 3× the listings mix tidy examples with tired ones, and a careful buyer can do well — but the exact figure for one car depends on its mileage and history, which is what the valuation tool is for.
Dealer or private seller
On the Audi A6 the forecourt markup works out at 10% over a private sale of the same year. Both figures are measured against the median for the same model year, so age is out of the comparison and what remains is the markup itself.
| Seller | Listings | vs median year | Average asked |
|---|---|---|---|
| Dealer | 487 | +14.9% | $12,900 |
| Private seller | 174 | +4.8% | $7,758 |
The gap comes to 10.1 percentage points. Some of that buys something real — reconditioning, a warranty, paperwork handled. The rest is the cost of not looking further.
How fast price falls with mileage
Taken from a single model year — 2014, the one with the most Audi A6 listings — so the curve shows mileage alone rather than age creeping in alongside it. Between the 75–100k and 150–175k bands the asking price falls 53%.
| Mileage | Price drop | Listings |
|---|---|---|
| 75–100k miles | 23 | |
| 100–125k miles | 36 | |
| 125–150k miles | 8 | |
| 150–175k miles | 9 |
Between the lowest and highest mileage bands the asking price falls 53%. Most of that drop happens early: the first hundred thousand miles cost far more than the second.

How we count
The Audi A6 figures here come from 764 live listings, 1997–2026 — asking prices, not sale prices. Sellers ask more than they get, so treat these as the top of the range, not the bottom.
Percentages here are never plain averages: each listing is first turned into its ratio against the median for its own model year, and those ratios are averaged instead. Without that step the numbers lie confidently — a flat average across 1997–2026 would mostly measure which years happen to be for sale this week. Slices too thin to survive the test are dropped rather than dressed up with an error bar, which for the Audi A6 leaves 19 model years standing. The full method, with the traps it avoids →
Frequently asked questions
How much does a used Audi A6 cost?
The median asking price is $9,650 across 764 live listings, ranging from about $2,988 for a 2001 to $58,999 for a 2026. These are asking prices — sellers generally accept less.
Is it cheaper to buy a A6 from a private seller?
Yes, by roughly 10 percentage points. Dealers ask +14.9% against the median for the same model year, private sellers +4.8%. Part of that gap pays for reconditioning and a warranty; the rest is the price of convenience.
Where is the cheapest place to buy a A6?
Of the states with enough listings, WI asks least at -11.4% against the national median, and CO most at +33.2%. On a $20,000 car that spread is worth a long drive.
Why do prices for the same year vary so much?
Among 2003 cars the dearest asks 6.9× what the cheapest does. Mileage, service history and title status explain most of it — which is why an average price for an older car tells you very little on its own.
