PRICE TRENDS & APPRECIATION
The market for the Audi S4 (B6) has shown a consistent decline over recent quarters. For instance, the median price in 2025-Q4 was $10,750, which decreased to $11,000 in 2026-Q1 and further to $11,000 in 2026-Q2. This indicates a downward trajectory, with the most significant drop occurring from 2024-Q4 to 2025-Q1, where the median price fell from $9,100 to $16,625. Overall, the average price has decreased significantly compared to historical sales, indicating a depreciating market.
Auction Market Dynamics
The sell-through rate stands at 87.2%, indicating a relatively healthy auction environment. However, the median price for sold vehicles at $12,250 contrasts sharply with the median high bid of $9,500, revealing a reserve gap that suggests sellers may have unrealistic price expectations. The ratio of sold (129) to unsold (8) vehicles indicates that while there is demand, sellers may need to adjust their expectations to align with buyer willingness, as evidenced by the high number of high bids (11) that did not result in sales.
Configuration Value Guide
The body style breakdown shows that the Sedan configuration is the most common, with 29 units averaging $8,412 and a median price of $6,500. The Cabriolet configuration, while less common (11 units), commands a slightly higher average price of $8,734 and a median of $8,995. The Wagon and Roadster configurations are rare, with only one unit each, priced at $6,995 and $4,999 respectively. The 2004 model year averages $10,968, while the 2005 model year averages $9,209, indicating that earlier models may command a premium.
Mileage Impact
Mileage significantly impacts pricing for the Audi S4 (B6). Vehicles with under 50,000 miles average $16,459, while those between 50,000 and 100,000 miles average $10,518. In contrast, vehicles with over 100,000 miles average only $7,753. This data indicates that buyers are willing to pay a premium of approximately $5,941 for low-mileage vehicles compared to those with higher mileage.
Regional Pricing
Geographic distribution reveals that the West region has the highest number of listings (38) with an average price of $9,460. The South follows with 12 listings averaging $10,272, while the Northeast has 6 listings averaging $8,400. The Midwest has the lowest average price at $8,350 with only 4 listings. This suggests potential arbitrage opportunities for buyers in the West and South, where prices are comparatively higher.
Market Health Indicators
The average days on market is 67, with a median of 54 days, indicating that vehicles are selling relatively quickly. However, the presence of 27 listings with price reductions suggests some softness in demand, as sellers may be adjusting prices to attract buyers. The introduction of 6 new listings this week indicates a steady supply in the market.
Investment Outlook
Given the current trend direction of depreciation 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, as the market is currently favoring buyers, and prices are likely to continue to decline unless market dynamics shift.
Buying Recommendations
For potential buyers, focusing on the Sedan and Cabriolet configurations, particularly those with lower mileage, is advisable. Target price ranges should be between $8,000 and $12,000 for vehicles in good condition. Given the reserve gap observed in auction outcomes, buyers should approach bidding with realistic expectations, considering the median sold price of $12,250 as a benchmark for negotiations.
