With 126 sold vehicles compared to 11 high bids and only 1 removed listing, sellers are generally meeting buyer expectations. The median price for sold vehicles is $14,500, while the median high bid is $17,000, suggesting a reserve gap where sellers may be holding out for higher prices than buyers are willing to pay. This gap indicates that while there is strong interest, sellers may need to adjust their expectations to facilitate sales.
Configuration Value Guide
The body style breakdown indicates that the only configuration available is the Convertible, which commands an average price of $19,069. This suggests that the Convertible variant is highly sought after, likely due to its performance and aesthetic appeal. The price by year data shows that 2004 models average $16,377, while 2005 models average $14,638. This indicates that the 2004 model year commands a premium, likely due to higher sales volume and desirability.

Regional Pricing
Geographic distribution shows that the West region has the highest average price at $15,562, while the South region has the lowest at $12,481. This suggests potential arbitrage opportunities for buyers in lower-priced regions, particularly if they are willing to invest in transportation costs for vehicles located in higher-priced areas.
Market Health Indicators
The average days on market is 50, with a median of 42 days, indicating that listings are selling relatively quickly. However, the presence of 9 listings with price reductions suggests that some sellers may be adjusting their expectations in response to market dynamics. The introduction of 5 new listings this week indicates a steady supply, which could impact future pricing if demand does not keep pace.
Investment Outlook
Given the current appreciating trend and the strong sell-through rate, the Mazdaspeed Miata appears to be a solid investment opportunity. The consistent price increases over the past quarters suggest that this asset class is likely to continue appreciating, making it a favorable hold for collectors and enthusiasts.
Buying Recommendations
Potential buyers should focus on 2004 models, which have shown higher average prices and sales volume. Targeting vehicles with under 50,000 miles can yield a premium, but buyers should be prepared to negotiate based on the current market dynamics. Given the reserve gap observed in auction outcomes, it is advisable for buyers to set realistic bidding limits, ideally below the median high bid of $17,000, to increase the likelihood of successful purchases.
