1965 BUICK SKYLARK GS, THE FASTER SKYLARK
The Grand Sport was an option package available on Buick’s midsized Skylark line. 1965 was the first year for the GS. At the time, the Skylark had a 300ci V8, for the Grand Sport version got a 401 V8 with much better performance. However, at that time GM had a policy that limited engine size to 400ci for midsized cars, so Buick under-stated the engine size, calling their 401 a 400. This was the famous “Buick Nailhead V8”, which gained quite a reputation for itself on the streets and at the track during the 1950s, but was now becoming woefully obsolete.
1965 BUICK SKYLARK, THE NICER MUSCLE CAR
In keeping with their more mature, higher-end image, Buick elected to make their muscle car decidedly more luxurious than their competition, mostly from their fellow GM divisions (read that: Chevrolet Chevelle SS and Pontiac GTO). The Grand Sport was a solid peformer in its own right, and quickly gained a reputation as a fast car on the street, but they were also a comfortable car that was easy to live with. The Grand Sport was never a high-volume seller like the Chevelle or the GTO, selling only around 15,000 units in 1965, its introductory year.
