Alvis was a prestigious car manufacturer that also made military vehicles. Its name existed until the beginning of this century. Its Red Triangle logo was once seen at Grand Prix races where their innovative front-wheel-drive cars made their debut. Alvis was also known for its conservative commercial models, as well as small to mid-size high-end touring cars. The chief engineer of Alvis in the l930s, Smith-Clark, designed the Speed 20, which was praised as one of the best performance cars in Britain at the time. This sporty model was given the in-line 6-cylinder engine from the earlier Alvis Silver Eagle. The 20SA made its debut in 1932 with a straight 6 OHV 2,511cc displacement motor. Then from l934 and beyond the 20SC was upgraded to 2,762cc. This entry is a drophead coupe made by Charlesworth. Its well-balanced proportions and exquisite details certainly make this vehicle a showstopper.
