The median asking price for a used Audi S4 is $15,000 across 277 listings. A 2023 costs about $43,990; a 2005 about $6,500. But the same year can differ wildly: among 2010 cars the dearest asks 4.9 times what the cheapest does — condition, mileage and title do the rest.

A spread near 1.5× means the market agrees what a Audi S4 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 S4 the forecourt markup works out at 19% 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 | 144 | +14.5% | $20,891 |
| Private seller | 101 | -4.2% | $11,673 |
The gap comes to 18.7 percentage points. Some of that buys something real — reconditioning, a warranty, paperwork handled. The rest is the cost of not looking further.
Which options hold value
The single biggest swing on a Audi S4 is transmission: MANUAL asks +29% against the median of its own model year. Every figure here uses the same normalisation — an average premium or discount measured within each year, never across them.
| Option | Listings | vs median year | |
|---|---|---|---|
| Transmission | Manual | 69 | +29.2% |
| Transmission | Automatic | 161 | -4.0% |

States where the Audi S4 asks least and most, measured against the national median for each model year. Dearest is MN at +43%, cheapest CA at +0% — 43 points apart, which on a $15,000 car is roughly $6,510.

How we count
The Audi S4 figures here come from 277 live listings, 1994–2024 — 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 1994–2024 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 S4 leaves 10 model years standing. The full method, with the traps it avoids →
Frequently asked questions
How much does a used Audi S4 cost?
The median asking price is $15,000 across 277 live listings, ranging from about $6,500 for a 2005 to $43,990 for a 2023. These are asking prices — sellers generally accept less.
Is it cheaper to buy a S4 from a private seller?
Yes, by roughly 19 percentage points. Dealers ask +14.5% against the median for the same model year, private sellers -4.2%. 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 S4?
Of the states with enough listings, CA asks least at -0.3% against the national median, and MN most at +43.1%. On a $20,000 car that spread is worth a long drive.
Why do prices for the same year vary so much?
Among 2010 cars the dearest asks 4.9× 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.
