In the disco days of the 1970s, even supercars were cocaine-thin. Meet the Aston Martin Lagonda, a four-door exotic that lived on dinner mints and hot water. Designed by AM penman William Towns — undoubtedly wearing a very large cravat at the time — the Lagonda was as beautiful a car as ever resembled a pencil box. Mechanically, it was a catastrophe, Aston Martin’s Dunkirk. The company decided to build the Lagonda with a brace of cutting-edge, computer-driven electronics and cathode-ray displays, which would have been very impressive if any of them ever worked. NASA couldn’t have built this car, much less the heirs to Joseph Lucas, the British electronics’ famous “Prince of Darkness.” Still, I’d kill to have one of these cars, and the O-scope and multi-meter to fix it.
