PRICE TRENDS & APPRECIATION
Analyzing the quarterly trends, the most recent quarter (2026-Q2) shows a significant drop in sales with only one unit sold at a median price of $9,950. In contrast, the previous quarter (2025-Q3) had four units sold at a median price of $19,400. This fluctuation indicates a potential decline in market interest or buyer sentiment. The average price in 2024-Q4 was notably high at $302,750, but this may not be indicative of a broader trend given the limited sales volume.
Auction Market Dynamics
The sell-through rate stands at 77.6%, indicating a relatively healthy auction market. However, the median price for sold vehicles ($27,443) is significantly higher than the median high bid ($12,544), suggesting a reserve gap where sellers may have unrealistic price expectations. This discrepancy indicates that while buyers are willing to bid, sellers are not accepting these bids, which could lead to a stagnation in sales if not addressed.
Configuration Value Guide
The body style breakdown indicates that all active listings are Coupes, with an average price of $17,158 and a median price of $16,500. The price by year data shows that the 1989 model commands a higher average price of $33,640 compared to other years, suggesting that buyers may place a premium on specific model years, particularly those that are more desirable or rare.
Mileage Impact
Mileage analysis reveals that vehicles with under 50,000 miles average $19,000, while those with over 100,000 miles average $22,671. This indicates that buyers are willing to pay a premium of approximately $3,671 for lower mileage vehicles, highlighting the importance of mileage in pricing strategy.
Regional Pricing
Geographic distribution shows that the West region has the highest number of listings (13) with an average price of $13,696. The Midwest region, while having only 2 listings, shows a significantly higher average price of $56,000, suggesting potential arbitrage opportunities for buyers in that region. The South and Northeast regions have average prices of $14,500 and $16,500, respectively, indicating a relatively stable pricing environment across these areas.
Market Health Indicators
The average days on market is 47, with a median of 67 days, suggesting that listings are moving at a moderate pace. The presence of 8 listings with price reductions indicates some softness in demand, while the introduction of 4 new listings this week suggests a steady supply. The sell-through rate of 77.6% further supports the notion of a balanced market, but the reserve gap observed in auction outcomes may indicate a need for sellers to adjust their expectations.
Investment Outlook
Given the current trend direction is classified as "insufficient data," and the fluctuations in quarterly sales, it is challenging to provide a definitive investment outlook. However, the historical sales data suggests that the SEC (C126) remains a niche market with potential for appreciation, particularly for well-maintained models from desirable years.
Buying Recommendations
Potential buyers should focus on Coupes from the 1989 model year, as they command higher prices and may offer better investment potential. Target price ranges should be between $15,000 and $25,000 for models in good condition, particularly those with lower mileage. Buyers should also be cautious of listings with high asking prices that exceed recent auction results, as this may indicate unrealistic seller expectations.
