Buick’s 1987 Grand National is the final hurrah, a sleek, black vision on the Regal platform. Among the 27,590 Turbo Regals, the lighter WE4 (Turbo T) stands out with its aluminum components. Even rarer is the GNX, with only 547 units boasting special interiors and performance tweaks straight from McLaren Performance Technologies. This “Darth Vader car” sports a turbocharged V6, achieving 0-60 in 4.3 seconds, proving V6s can rule the road, even when V8s were all the rage!
