PRICE TRENDS & APPRECIATION
The quarterly trends indicate a declining market, particularly evident in the most recent quarters. For instance, in Q3 2026, the average price dropped to $25,780 with a median of $20,480, down from a median of $34,720 in Q1 2026. This represents a significant decline in value over a short period. The overall trend shows that prices are decreasing, and potential buyers may benefit from negotiating lower prices based on this trajectory.
Auction Market Dynamics
The sell-through rate stands at 76.3%, indicating a relatively healthy auction environment. However, the median price for sold vehicles ($28,600) is significantly higher than the median high bid ($23,000), suggesting that sellers may have unrealistic expectations. The ratio of sold to unsold vehicles indicates that while many vehicles are selling, there is a notable gap between what buyers are willing to pay and what sellers are asking, which could be a signal for buyers to negotiate more aggressively.
Configuration Value Guide
In terms of body style, the Convertible configuration commands a premium, with an average price of $33,188 and a median of $26,900. In contrast, Sedans average $6,378 with a median of $3,500. The Coupe style, while less common, averages $26,530 with a median of $19,900. This data suggests that buyers looking for investment potential should prioritize Convertibles and Coupes, particularly from desirable model years.
Mileage Impact
Mileage significantly impacts pricing, with vehicles under 50,000 miles averaging $31,656, while those over 100,000 miles average only $9,341. This indicates that buyers are willing to pay a premium of approximately $22,315 for low-mileage vehicles, highlighting the importance of mileage in valuation.
Regional Pricing
Geographic distribution shows that the West has the highest average price at $23,639, while the South has the lowest at $18,440. This suggests potential arbitrage opportunities for buyers in the South looking to acquire vehicles that may appreciate in value when sold in the West.
Market Health Indicators
The average days on market is 84, with 25 new listings this week and 47 listings experiencing price reductions. This indicates a softening demand, as many sellers are adjusting prices downward to attract buyers. The relatively high number of new listings suggests that supply is adequate, but the market may be cooling.
Investment Outlook
Given the current depreciation trend and the recent quarterly price declines, the Bonneville may not be an appreciating asset class in the short term. Buyers should approach this market with caution, focusing on specific configurations and model years that have historically performed better.
Buying Recommendations
Potential buyers should focus on acquiring Convertibles and Coupes from the 1960s, particularly the 1964 model, which has shown strong sales. Target price ranges should be below the current median asking price of $15,450, especially considering the downward price trend. Buyers should also be prepared to negotiate aggressively, given the gap between sold prices and high bids in the auction market.
