The Aston Martin DB4, the DB5 (famously driven by fictional character James Bond) and the DB6 were named after David Brown’s initials. He entrusted Touring Superleggera to design their next generation GT after the introduction of the successful DB2. The license agreement enabled Aston Martin to use the design and the Superleggera construction method at Newton Pagnell plant against a licence fee of £9 for each of the first 500 bodies and £ 5 for each further unit.
