PRICE TRENDS & APPRECIATION
The quarterly trends indicate a consistent depreciation in prices over recent quarters. For instance, the median price in 2026-Q1 was $49,633, which dropped to $45,575 in 2026-Q2, reflecting a decline of approximately 4.2%. The most recent quarter (2026-Q3) shows a further decrease, with only 2 sales at a median price of $37,995. This trend suggests that the market is not appreciating and may continue to decline unless demand increases significantly.
Auction Market Dynamics
The sell-through rate stands at 69.1%, indicating a relatively healthy auction environment. However, the median price for sold vehicles ($49,604) is notably lower than the median last asking price ($53,945), revealing a reserve gap that suggests sellers may have unrealistic expectations. The ratio of sold (76) to high bid (32) indicates that while buyers are willing to bid, many sellers are not accepting offers, which could further pressure prices downward.
Configuration Value Guide
The body style breakdown shows that the Coupe configuration commands a higher average price of $49,662 compared to the Sedan at $40,930. The Cabriolet also holds a premium at $48,051. In terms of model year pricing, the 2021 models average $59,159, while 2017 models average $43,394. This indicates that newer models are significantly more valuable, while older models may offer better value for budget-conscious buyers.
Mileage Impact
Mileage analysis reveals that vehicles with under 50,000 miles command an average price of $53,795, while those with 50,000 to 100,000 miles average $40,086. Vehicles exceeding 100,000 miles average only $29,158. This data indicates that buyers are willing to pay a premium of approximately $13,709 for low-mileage vehicles, highlighting the importance of mileage in pricing.
Regional Pricing
Geographic distribution shows that the West has the highest average price at $45,469, while the South has a lower average of $42,733. The Northeast and Midwest show average prices of $45,610 and $52,140, respectively. Buyers may find better deals in the South, where prices are lower compared to other regions.
Market Health Indicators
The average days on market is 57, with 112 listings having price reductions, suggesting a softening demand. The introduction of 37 new listings this week indicates a steady supply, but the high number of price reductions indicates that sellers may be struggling to meet buyer expectations.
Investment Outlook
Given the current depreciation trend and the recent quarterly price declines, the Mercedes-Benz C63 AMG / C63 S (W205) does not appear to be an appreciating asset class at this time. It may be prudent to hold off on investments until market conditions stabilize or show signs of recovery.
Buying Recommendations
Potential buyers should focus on 2017 and 2018 models, particularly in the Coupe configuration, which offers better value. Target price ranges should be around $40,000 to $50,000 for models with under 50,000 miles. Buyers should also be cautious of high asking prices and consider bidding strategies that reflect the current market realities, particularly given the observed reserve gap in auction outcomes.
