- Colour
- Anthracite Grey
The Aston Martin Lagonda Series 1 is among the rarest of post-war Aston Martins, with only eight examples produced between 1974 and 1976. Chassis 12006, the sixth car built in period, was displayed at the 1975 Earls Court Motor Show and originally left the factory in Cosmic Fire Royal Claret with a black interior. It was subjected to a comprehensive rebuild by RS Williams in 2006, during which the original 5.3-litre engine was replaced with the firm's 7.0-litre conversion producing approximately 480bhp and 550lb/ft of torque, alongside extensive chassis, interior, and refinement upgrades. The car has covered only around 3,200 miles since that restoration.
