The 1965-1967 Buick Skylark Gran Sport was Buick's mid-size hot rod of the mid-1960s. It was introduced as an option package for the Skylark coupe, hardtop, and convertible, then graduated to separate-series status for 1966.

Power in the first two years came from the big-block 401 V-8 from the full-size Buicks, the pentroof engine that dated from Buick's original 1953 "Fireball" ohv V-8. For 1967, an all-new block arrived with semi-wedge heads, and the model designation changed to GS400. That same year, Buick introduced a junior muscle car, the GS340, powered by an enlarged version of its small-block V-8, and front disc brakes were added to the options list.

All Gran Sports were built on the heavier convertible chassis, and had a heavy-duty suspension and the requisite scoops, stripes, and bulges as battle dress. Quite quick (0-60 mph came up in as little as 6.0 seconds flat according to one contemporary road test), the GS was also one of the better-handling performance machines of the era, and had Buick's customary luxury and solid construction quality.

Prices escalated during the 1980s, making this a good alternative to an Oldsmobile 4-4-2 or Pontiac GTO. The low-production convertibles are naturally the most desirable models.
