Alvis Silver Crest is a 4 or 5 passenger saloon car or coupé produced by the Alvis Car and Engineering Company between 1937 and 1940. It used advanced technology intended to provide a top speed in excess of 80 miles per hour (129 km/h) and sold at a relatively high purchase price. Announced in mid-August 1937, production ended just before the war when a new-shaped body entered production.
