Lagonda Series 1 1974. Following the Lagonda DBS, Aston Martin tried again with the four-door V8 Saloon, which would later be named the Lagonda Series 1. Measuring 4.93 meters in length and featuring a highly controversial horseshoe-shaped chrome grille, the new Lagonda was launched in the midst of the oil crisis and was ultimately a failure, with only seven cars sold.
