After the Second World War the company continued to develop, producing coupes for Alvis, Daimler and Humber and station wagons for Land Rover. Amongst development projects undertaken for several companies were the Jet 1 and the Austin Healey sports car prototype.
The luxurious convertibles and saloons built on the Lagonda chassis prompted the 1955 acquisition of the company by David Brown. The company became Aston Martin Lagonda Ltd.
