Aston Martin has used the Vantage name on a number of vehicles, normally indicating a high-performance version of another model. In one case, during 1972–1973, the Vantage was a distinct model, being a straight-6 powered version of the DBS, a car that had been launched as a straight-6 but was by that time V8-powered (as the DBS V8). Despite the Vantage nameplate, the 1972-1973 Vantage was in reality the least powerful model in the manufacturer's range at the time. It was also the least expensive, serving as an entry-level Aston Martin. Visual cues include a unique 2-headlight front clip with DB6-like grille. It was also the last Aston Martin to come equipped with wire wheels. Just 71 examples were built. The Vantage was the last straight-6 Aston Martin until the 1993 DB7.
