1972 Buick Gran Sport

1972 Buick GS 455 Stage 1 â?" Heavily Optioned Tribute Car in Wine Mist with Thru-Bumper Exhaust Why This Car Is Special The 1972 Buick GS 455 Stage 1 occupies a specific and important place in American automotive history. By 1972, the muscle car era was effectively over. Insurance rates had climbed, compression ratios had been dropped to accommodate low-lead fuel, and emission regulations were beginning to reshape what Detroit could offer. The 1972 model year would be the last for the Buick GS as a distinct, purpose-built performance model before it was folded back into the Skylark lineup. That makes any legitimate 1972 Buick GS 455 Stage 1 a genuine last-of-its-kind machine â?" and one that collectors have steadily recognized over the past two decades.
