William Towns penned the Aston Martin Lagonda and Michael Loasby engineered the car that was presented at the 1976 London Motor Show. The Lagonda had digital instrumentation and computer management, the first car to do so. Known as the 'Series II', it was in fact a new 'folded paper' design for 1976, compared to his 4-door version of the DBS for 1974. A 5340cc V8 engine powered the Lagonda, and deliveries did not commence until 1979. From 1983 BBS alloy wheels were fitted, and in 1987 a Series III car was announced with new instrumentation. The Geneva Motor Show of 1987 saw the revised Aston Martin Lagonda, revisited by William Towns, de-sharpened and losing its pop-up headlamps. The Series II, III and IV Lagondas sold until 1989 with 645 leaving the plant.
