The Alvis TC 108G was a British sporting car made by Alvis cars between 1956 and 1958. Coachbuilders Graber of Switzerland had produced some bodies for the TC21 that were much more up to date than the standard offering from Mulliners. Mulliners was increasingly coming under the control of Standard Triumph, they were purchased by them in 1958, and the body supply had been getting difficult. Alvis's other main supplier was Tickford and they were bought by David Brown to use for his Aston Martin company. It was therefore decided to make the Graber style the basis of a new model and the rights were bought resulting in the TC 108G.
