The quarterly trends indicate a generally appreciating market. For instance, in 2025-Q4, the median price reached $15,000, up from $11,750 in 2024-Q4, reflecting a significant increase. The average price in 2026-Q1 was $15,266, suggesting that the upward trend is continuing into 2026. The most recent quarter (2026-Q2) saw a slight decrease in sales count but maintained a median price of $15,000, indicating price stability despite lower sales volume.
Auction Market Dynamics
The sell-through rate stands at 91.4%, indicating a healthy market where most vehicles listed are sold. The median price for sold vehicles is $14,001, while the high bid median is significantly higher at $17,000, suggesting a reserve gap where sellers may have unrealistic expectations. This gap indicates that while buyers are willing to pay up to $17,000, sellers are not accepting these bids, which may lead to prolonged listings.
Configuration Value Guide
The body style breakdown shows that the Convertible configuration is the most common, with 9 listings averaging $8,810 and a median price of $7,000. In contrast, the 2004 model year commands a higher average price of $12,525 compared to $13,520 for the 2005 model year. This suggests that while both years are popular, the 2005 model may offer better value for buyers looking for a slightly newer vehicle.
Mileage Impact
Mileage significantly impacts pricing. Vehicles with under 50,000 miles average $17,573, while those between 50,000 and 100,000 miles average $12,397, and vehicles over 100,000 miles average only $8,425. This data indicates that buyers are willing to pay a premium of approximately $5,176 for low-mileage vehicles compared to those with over 100,000 miles.
Regional Pricing
Geographic distribution reveals that the West has the highest average price at $12,486, while the South has the lowest at $9,386. This suggests potential arbitrage opportunities for buyers in the South, where prices are significantly lower compared to the West.
Market Health Indicators
The average days on market is 29, with a median of 33 days, indicating that listings are selling relatively quickly. However, the presence of 17 listings with price reductions suggests that some sellers may be adjusting their expectations to align with market realities. The introduction of 2 new listings this week indicates a stable supply.
Investment Outlook
Given the appreciating trend and the strong sell-through rate, the Mazdaspeed Miata (NB turbo) appears to be a solid investment. The consistent demand and rising prices suggest that this model is likely to continue appreciating, making it a favorable asset class for collectors.
Buying Recommendations
Potential buyers should focus on 2004 and 2005 models, ideally those with mileage under 50,000 miles, as these configurations command higher prices but also offer better long-term value. Target price ranges should be between $12,000 and $15,000 for well-maintained examples. Buyers should be cautious of listings with high asking prices relative to recent sales data, particularly those exceeding the median sold price of $14,001, as these may indicate sellers with unrealistic expectations.
