History
Pontiac Grand Prix SJ
The Grand Prix SJ represented Pontiac's successful blending of personal luxury and performance during the muscle car era's final years. Its 455 cubic inch V8 produced 370 horsepower, making it one of the most powerful luxury coupes available. The distinctive split grille, hideaway headlamps, and long hood/short deck proportions created dramatic presence. With rally gauges, bucket seats, and handling suspension, the SJ offered genuine driver engagement alongside luxury appointments.
