"Priced and powered in line with its competition...the GS 400 is the most luxurious of the lot, yet takes a back seat to none in performance," maintained Car Life magazine.

In 1968 and 1969 Buick offered the GS 400 in a convertible and hardtop model. Standard issue of the GS 400 was a 400 cubic inch (6.6L) engine (with likely lower stated horsepower rating to keep insurance premiums lower) of 340 horsepower (350 hp stage 1 ) and 440 ft. lbs. torque, a four barrel Rochester Quadrajet carburetor, dual exhaust, 2.93 standard gear ratio optional ( limited slip differential, (3.64 stage 1 option, 3.42 with A/C ), and the available three speed turbo Super Turbine 400 automatic transmission (revered as the finest automatic transmission ever built, and commonly called Turbo Hydramatic 400), U-shape Hurst (automatic transmission) shifter and linkage, located on a center console. A 1968 or 1969 GS400 equipped with the TH400 auto transmission was faster off the line than many of its contemporaries thanks to an unusually "low" 1st gear. Shift pattern for the TH400 from most forward position is Park, Reverse, Neutral, Drive, Second, First. A standard 3 spd or optional 4 spd manual gearbox was also available. Compression ratio on this engine was a very sensible 10.25:1, which allowed for the use of any grade gasoline to be used in normal driving without pinging.

Like all of the GM versions of this body style in this period, the convertible chassis was considerably more robust that the hardtop version. In fact, the convertible chassis was a full box frame chassis that had numerous lightening holes. The hardtop chassis was a 3/4 box frame with no lightening holes. The only GM hardtop ever built with the "Swiss cheese" convertible chassis was the GTO Judge. Same chassis. All of the GS400 convertibles were built at GM's Fremont, California assembly line.
