The Aston Martin DB7 is a grand tourer which was produced by Aston Martin from September 1994 to December 2004. The grand tourer was available either as a coupé or a convertible. The prototype was complete by November 1992 and debuted at the Geneva Motor Show in March, 1993; the car was styled by Ian Callum and Keith Helfet. The six-cylinder DB7 (based on the Jaguar non-supercharged engine AJ6) was positioned as an "entry-level" model below the hand-built V8 Virage introduced a few years earlier. This model was the highest production Aston Martin vehicle ever, with more than 7,000 built before it was replaced by the DB9.
