Buick Grand National

The Buick Grand National began as a trim package but evolved into an icon of 1980s American muscle. From 1984, the car adopted its famous all-black paint scheme and a turbocharged 3.8L V6 engine. Power climbed throughout its run, with the intercooled 1986 and 1987 models becoming the most sought-after for their impressive performance that could challenge contemporary V8s.

Collectors prize the Grand National for its menacing looks and unique engineering. It was one of the quickest American cars of its era, and its reputation has only grown. The final 1987 models are particularly desirable, especially the ultra-rare GNX variant, which was a limited-production, high-output version that stands as the ultimate prize for Buick enthusiasts.

The market for Grand Nationals is mature and stable, with an average sale price over $43,000. Low-mileage, original examples from 1986 and 1987 fetch premium prices. While project cars can be found, buyers pay a significant premium for well-maintained cars, reflecting their status as a true collector's item.

Prices range from $1,500 for project cars to $139,500 for exceptional, low-mileage examples.
