PRICE TRENDS & APPRECIATION
The quarterly trends indicate a declining market for the Audi S4 (B6). For instance, in 2025-Q4, the median price was $10,750, which dropped to $12,495 in 2026-Q1, before slightly increasing to $13,300 in 2026-Q3. However, the overall trend shows a decrease in median prices over the past year, with the most significant drop occurring from 2024-Q4 to 2025-Q1, where the average price fell from $8,693 to $16,101. This suggests that while there may be short-term fluctuations, the long-term trajectory remains downward.
Auction Market Dynamics
The sell-through rate stands at 86.3%, indicating a relatively healthy auction market. However, the median price for sold vehicles is $12,175, while the median high bid is $11,500, revealing a reserve gap where sellers may have unrealistic expectations. The ratio of sold (126) to unsold (8) vehicles suggests that buyers are willing to pay close to the asking prices, but sellers may need to adjust their expectations to align with market realities.
Configuration Value Guide
The body style breakdown shows that the Sedan configuration is the most common, with 30 units averaging $6,278. The Cabriolet, with 19 units, commands a higher average price of $8,748. The Wagon configuration, although less common with only 3 units, averages $8,497. This indicates that buyers may be willing to pay a premium for Cabriolet models, while Sedans represent the best value for budget-conscious buyers.
Mileage Impact
Mileage analysis reveals that vehicles with under 50,000 miles command an average price of $15,200, significantly higher than the $7,005 average for those with over 100,000 miles. This indicates that buyers are willing to pay a premium of approximately $8,195 for lower-mileage vehicles, highlighting the importance of mileage in pricing strategy.
Regional Pricing
Geographic distribution shows that the West region has the highest average price at $8,887, while the South region has the lowest at $4,957. This suggests potential arbitrage opportunities for buyers in the South, where prices are significantly lower compared to the West.
Market Health Indicators
The average days on market is 65, with a median of 40 days, indicating that while some listings are selling quickly, others may be lingering due to high asking prices or low demand. The presence of 25 listings with price reductions suggests that sellers are adjusting their expectations in response to market conditions.
Investment Outlook
Given the current depreciation trend and the significant year-over-year price decline, the Audi S4 (B6) does not appear to be an appreciating asset class at this time. Potential investors should be cautious and consider holding off on purchases until market conditions improve.
Buying Recommendations
For prospective buyers, the best value configurations are the Sedan models, particularly those with lower mileage. Target price ranges should be around $6,000 to $8,000 for higher-mileage vehicles, while lower-mileage options should be pursued at prices below $15,000. Buyers should also be aware of the reserve gap in auctions and consider bidding strategies that reflect realistic market values, particularly focusing on sold prices rather than high bids.
