The median price for sold vehicles is $14,400, while the median high bid is $15,500, suggesting a reserve gap where sellers may have unrealistic expectations.

The 2004 model year commands a slightly higher average price of $13,898 compared to the 2005 model at $14,263. This indicates that while both years are popular, the 2005 model may offer a premium due to its rarity in the market.

Market Health Indicators
The average days on market is 44, with a median of 48 days. The presence of 10 listings with price reductions indicates some soft demand, but the new listing rate of 1 per week suggests a stable supply. The high sell-through rate further supports a healthy market environment.
Investment Outlook
Given the stable price trend and slight appreciation observed in recent quarters, the Mazdaspeed Miata appears to be a solid investment. The combination of low inventory and high demand suggests that this asset class may continue to appreciate, making it a hold recommendation for current owners and a potential buy for new investors.
Buying Recommendations
For prospective buyers, focusing on the 2005 model year with lower mileage (under 50k miles) is advisable, as these vehicles command higher prices and are likely to appreciate further. Target price ranges should be between $12,000 and $15,000 for models in good condition. Buyers should also be cautious of listings with high asking prices that do not align with recent auction outcomes, as these may indicate sellers with unrealistic expectations.
