The Aston Martin DB3S was a sports racing car built by Aston Martin as a replacement for the heavy and uncompetitive Aston Martin DB3. In total 31 cars were made, with 11 works cars and 20 cars being sold for customer use. The DB3S was introduced in 1953 and it proved somewhat more successful than the Aston Martin DB3. The DB3S was later replaced in 1956 by the DBR1.
The 11 works cars had chassis numbers from DB3S/1 to DB3S/11, with the 11th works car never being raced by Aston Martin. The 20 customer cars had three digit chassis numbers, from DB3S/101 to DB3S/120. In 1994 one sanction 2 car was assembled from original spare parts at Aston Service Dorset. As the manufacturing right for all pre1960 Aston Martin were with the Farshaw family, this car carries chassis number DB3S/121.
Originally two works Aston Martin DB3S fixed head coupé's were made. The change was to make them more aerodynamic than the open top bodied cars. However, they were unstable at high speeds and both crashed at the 1954 24 Hours of Le Mans. Both coupé's were then rebuilt as open bodied cars.
Three of the customer cars were also fitted with similar coupé bodies.
