PRICE TRENDS & APPRECIATION
Analyzing the quarterly trends, the market appears to be appreciating, particularly in 2025. For instance, in Q3 2025, the median price reached $205,000, a significant increase from Q1 2025, where it was $101,987. The average price in Q2 2025 was $181,959, indicating a positive trajectory. However, the most recent quarter (Q1 2026) shows a single sale at $192,500, which may not provide a clear trend due to limited data.
Auction Market Dynamics
The sell-through rate stands at 76.8%, indicating a healthy market where a majority of vehicles sold at auction. The median price for sold vehicles is $148,900, while the high bid median is $170,000, suggesting a reserve gap where sellers may have unrealistic expectations. The ratio of sold (116) to unsold (30) vehicles indicates that while there is demand, some sellers are not meeting market realities, as evidenced by the high number of unsold listings.
Configuration Value Guide
The data does not provide specific body style breakdowns; however, the price by year indicates that the 1987 model commands the highest prices, with an average price of $217,408 and a median of $188,700. This suggests that buyers are willing to pay a premium for well-preserved 1987 models, which are the most common in the market.
Mileage Impact
The mileage analysis shows that vehicles with under 50,000 miles command an average price of $226,785, significantly higher than the average price for higher mileage vehicles. This indicates that buyers are willing to pay a premium for low-mileage examples, reinforcing the importance of mileage in valuation.
Regional Pricing
The geographic distribution indicates that most active listings are categorized as "Unknown" with an average price of $296,180, which may skew the perception of regional pricing. The West region has 2 listings with an average price of $99,250, suggesting a potential arbitrage opportunity for buyers in that area compared to the higher-priced listings.
Market Health Indicators
The average days on market is 27, with a median of 19 days, indicating that listings are selling relatively quickly. The lack of price reductions suggests stable demand, while the new listing rate of 1 per week indicates a limited supply, which could contribute to upward price pressure.
Investment Outlook
Given the current market dynamics and the appreciation observed in recent quarters, the Buick Grand National/GNX GNX appears to be a potentially appreciating asset class. However, the insufficient data on year-over-year price changes necessitates caution. A hold recommendation is advised for current owners, while prospective buyers should closely monitor market trends.
Buying Recommendations
For potential buyers, targeting well-maintained 1987 models with low mileage (under 50,000 miles) is advisable, as these configurations command higher prices and are likely to appreciate further. A realistic bidding strategy should consider the median sold price of $148,900, while being aware of the high bid median of $170,000 to avoid overpaying.
