Market Snapshot

PRICE TRENDS & APPRECIATION

Analyzing the quarterly trends, the market has shown fluctuations in median prices over the past few quarters. For instance, in Q4 2025, the median price was $11,975, while it dropped to $10,000 in Q2 2026. The average price in Q2 2026 was $9,960, indicating a potential depreciation trend. However, the average price in Q1 2026 was significantly higher at $15,600, suggesting volatility rather than a clear appreciation or depreciation trend.

Auction Market Dynamics

The sell-through rate stands at 85.9%, indicating a relatively healthy auction market. The median price for sold vehicles is $12,175, while the median high bid is $11,500, suggesting a reserve gap where sellers may have unrealistic expectations. The ratio of sold (128) to unsold (8) vehicles indicates that the majority of listings are successfully selling, but the presence of high bids that did not meet reserve prices suggests that buyers are cautious and may not be willing to meet sellers' expectations.

Configuration Value Guide

In terms of body styles, the Sedan configuration is the most common, with 45 listings averaging $7,281 and a median price of $7,000. The Cabriolet has 18 listings with an average price of $7,082 and a median of $5,125. The Wagon configuration, while less common with only 2 listings, has a higher median price of $8,495. This indicates that the Sedan and Cabriolet configurations are more accessible, while the Wagon may command a premium due to its rarity.

Mileage Impact

Mileage significantly impacts pricing for the Audi S4 (B6). Vehicles with under 50,000 miles average $15,251, while those in the 50,000 to 100,000-mile range average $9,453. In contrast, vehicles with over 100,000 miles average only $7,245. This data indicates that buyers are willing to pay a premium of approximately $5,798 for low-mileage vehicles compared to those with over 100,000 miles.

Regional Pricing

Geographic distribution shows that the West has the highest average price at $8,957 with 52 listings, while the Northeast has the lowest average price at $6,136 with 20 listings. The South and Midwest follow with average prices of $6,669 and $7,557, respectively. This suggests potential arbitrage opportunities for buyers in the Northeast and Midwest, where prices are lower compared to the West.

Market Health Indicators

The average days on market is 64, with a median of 42 days, indicating that listings are selling relatively quickly. However, the presence of 33 listings with price reductions suggests that some sellers may be adjusting their expectations downward in response to market conditions. The introduction of 9 new listings this week indicates a steady supply of vehicles entering the market.

Investment Outlook

Given the current trend direction is classified as "insufficient data," and the fluctuations in quarterly trends, the Audi S4 (B6) may not be a consistently appreciating asset class at this time. The volatility in pricing suggests that while there are opportunities for appreciation, particularly for low-mileage vehicles, caution is warranted.

Buying Recommendations

Potential buyers should focus on low-mileage configurations, particularly those under 50,000 miles, as they command a premium. Target price ranges for these vehicles should be around $15,000 to $18,000. Buyers should also consider negotiating on listings in the Northeast and Midwest, where prices are generally lower. If participating in auctions, be mindful of the reserve gap indicated by the difference between sold and high bid prices, and adjust bidding strategies accordingly to avoid overpaying.
