Buick GNX

The Buick GNX continues to command serious collector interest at a median of $225,000, up 25 percent over the past twelve months. This year-over-year movement tracks well with the car's broader appreciating trajectory, though the signal currently reads as HOLD given medium confidence in near-term momentum.

Only 547 GNX models were built, placing the car in genuine Holy Grail territory within the collectible automotive hierarchy. This extreme scarcity underpins its classification as an appreciating classic and drives consistent desirability among serious collectors, even as liquidity remains thin.

Transaction volume over the past year totaled seven sales, a sample size that reflects the thinness of the market but also its stability among high-net-worth buyers. The absence of active listings at present suggests current holders are not motivated to sell near these levels.

Cars changing hands average just over 4,000 miles, consistent with the careful stewardship typical of vehicles in this tier. Low mileage examples are now the standard expectation in the GNX market.

Base projections suggest the median could reach approximately $449,000 within three years and $567,000 within five years, implying roughly 99 and 152 percent appreciation respectively from current levels. These forecasts rest on sustained collector appetite for turbocharged 1980s American muscle and the car's unchanging scarcity as a production-limited artifact.
