Muscle cars’ glory days started to fade in the early ’70s, but a few model lines kept up the performance in spite of oncoming emission regulations. The 1971 Buick GS 455 did an admirable job — it was a banker’s hot rod with an edge, like an upscale LS5 Chevelle SS.
The Skylark-based GS line kept the two engines from 1970 in their 1971 cars, but dropped the compression ratio to run on low-lead, regular-grade fuel as per GM decree. The 455-ci V8 still proved a thunderous beast. The 315 horsepower is nothing to sneeze at, even if it was a drop from 350 the previous year. The primary fun factor comes from 450 lbs/ft of torque at 2,800 rpms. It’s more than enough to throw everybody in the back seat on hard acceleration. The 455 option cost just $164 on top of the regular Gran Sport.
The seller says “this car is in showroom condition,” as it was totally restored with NOS parts. It shows clean as a whistle in the photos, with no obvious blemishes on the outside or inside. The Stratomist Blue is complimented by the white soft top and upholstery.
Ninety four 1970–72 Skylarks sold on eBay Motors in the past year. Good to excellent examples averaged from $9k to over $16k. Gran Sports averaged from $16k to $29k, and convertibles can add a premium on top of that. Click here to see this drop-top Buick.
