The Buick Grand National models of the 80s wouldn't have existed, if their wasn't a predecessor model that inspired their creation. That predecessor was the Buick Gran Sports of the mid 60s - 70s. They were high performance luxury cars....
The Gran Sport model started out as a set of performance options available on a few different Buick models of the 60s, much like Chevrolet' s Super Sport(SS) option packages. But later, the Gran Sport became a top level performance package available only on the mid sized Skylark.
As with the 1987 GNX being the penultimate version of Grand Nationals, the GSX was the top-o-the-line version of the Gran Sport series. It came in specific colors set for each model year, and it included front and rear spoilers, stripes, badging etc.
This particular gem, comes with the extra heavy duty Muncie M22 4-speed manual, a posi rear, and the tip-top engine option, which was the 455 Stage 1. That engine produced more torque than any other automotive production engine for a very long time. These cars were known to often outperform even the Plymouth Hemi Cuda, which created an ongoing, 1/2 century rivalry between the 2 camps!
