7. 1970 Buick GSX Stage 1
The 1970 Buick GSX Stage 1 shattered expectations for Buick, combining luxury with muscle in a striking package.
With fewer than 700 produced, the GSX Stage 1 is both rare and respected for its monstrous 455 V8 and advanced engineering.
Strong resale values are the norm, with recent sales at Mecum and Barrett-Jackson hovering between $150,000 and $200,000.
Compared to other Buicks of the era, the GSX stands apart for its performance credentials and bold styling, making it a crown jewel for collectors seeking something unique in the muscle car pantheon.
