PRICE TRENDS & APPRECIATION
The quarterly trends indicate a declining market for the Audi S6 (C7). In 2025-Q3, the average price was $24,474 with a median of $23,250, but by 2026-Q1, these figures dropped to an average of $20,577 and a median of $17,000. This represents a significant decline in value over the past year. The most recent quarter (2026-Q3) shows only one sale at a median price of $29,500, which may not be indicative of a broader trend due to the low sales volume.
Auction Market Dynamics
The sell-through rate stands at 80.4%, indicating a relatively healthy auction environment. However, the median price for sold vehicles ($24,875) is notably higher than the median high bid ($21,000), suggesting a reserve gap where sellers may have unrealistic expectations. The ratio of sold to unsold/high_bid vehicles indicates that while buyers are willing to pay a certain amount, sellers are often not accepting these bids, which may lead to prolonged listings.
Configuration Value Guide
The body style breakdown shows that the Sedan configuration is the most common, with 91 units averaging $20,747 and a median price of $19,999. The price by year data indicates that the 2017 model commands the highest average price at $24,780, while the 2013 model averages $14,205. This suggests that newer models retain a premium, while older models depreciate more significantly.
Mileage Impact
Mileage analysis reveals that vehicles with under 50,000 miles command an average price of $35,380, while those with over 100,000 miles average only $17,267. This indicates a significant premium of approximately $18,113 for low-mileage vehicles, highlighting the importance of mileage in pricing.
Regional Pricing
Geographic distribution shows that the West region has the highest average price at $21,211, while the Northeast has the lowest at $18,092. This suggests potential arbitrage opportunities for buyers in the Northeast looking to purchase in the West, where prices are higher.
Market Health Indicators
The average days on market is 67, with 21 new listings this week and 48 listings having price reductions. This indicates a soft demand, as many sellers are adjusting their prices downward to attract buyers. The relatively high number of price reductions suggests that sellers may need to recalibrate their expectations to align with current market conditions.
Investment Outlook
Given the current depreciation trend and the significant decline in average prices, the Audi S6 (C7) does not appear to be an appreciating asset class at this time. Buyers may find better value in acquiring this model now, as prices are likely to continue to decline unless market conditions change.
Buying Recommendations
For potential buyers, targeting models from 2016 and 2017 may provide the best value, as these years command higher prices but also offer better features and performance. A target price range of $17,000 to $24,000 is advisable, particularly for vehicles with lower mileage. Buyers should be cautious of listings with high asking prices relative to recent sales, as these may indicate sellers with unrealistic expectations.
