One of the first American marquees was Buick when it was established in 1899 by David Dunbar Buick. General Motors was established in 1908 thanks to Buicks popularity. Later, Buick became GM’s premium brand targeting the wealthy of North America. The only marquee above Buick was the upscale luxury brand Cadillac. As of today, Buick’s largest market is China, with almost 80% of sales originating from there. In 1965 Buick introduced the “Gran Sport” name for high-performance cars built by Buick. The beauty of the GS cars was that they were a perfect blend of high-performance, luxury appointments and comfort. The first GS was the Skylark in 1965, which was eventually replaced by the Gran Sport 455. A rare chance to own a magnificent piece of performance history is now at hand in the form of this 1970 Buick GS 455 convertible with 91,287 miles on the odometer and the best part being that the seller reports it to be a one owner car.
