after having built a stake in 1987. Ford placed Aston Martin in the Premier Automotive Group, invested in new manufacturing and ramped up production. In 1994, Ford opened a new factory at Banbury Road in Bloxham to manufacture the DB7. In 1995, Aston Martin produced a record 700 cars. Until the Ford era, cars had been produced by hand coachbuilding craft methods, such as the English wheel. During the mid 1990s, the Special Projects Group, a secretive unit with Works Service at Newport Pagnell, created an array of special coach-built vehicles for the Brunei royal family. In 1998, the 2,000th DB7 was built, and in 2002, the 6,000th, exceeding production of all of the previous DB series models. The DB7 range was revamped by the addition of more powerful V12 Vantage models in 1999, and in 2001, Aston Martin introduced the V12-engined flagship model called the Vanquish which succeeded the aging Virage (now called the V8 Coupé). At the North American International Auto Show in Detroit, Michigan in 2003, Aston Martin introduced the V8 Vantage concept car. Expected to have few changes before its introduction in 2005, the Vantage brought back the classic V8 engine to allow Aston Martin to compete in a larger market. 2003 also saw the opening of the Gaydon factory, the first purpose-built factory in Aston Martin's history. The facility is situated on a 22-hectare (55-acre) site of a former RAF V Bomber airbase, with an front building for offices, meeting rooms and customer reception, and a production building. Also introduced in 2003 was the DB9 coupé, which replaced the ten-year-old DB7. A convertible version of the DB9, the DB9 Volante, was introduced at the 2004 Detroit auto show. In October 2004, Aston Martin set up the dedicated Aston Martin Engine Plant (AMEP) within the Ford Germany Niehl, Cologne plant. With the capacity to produce up to 5,000 engines a year by 100 specially trained personnel, like traditional Aston Martin engine production from Newport Pagnell, assembly of each unit was entrusted to a single technician from a pool of 30, with V8 and V12 variants assembled in under 20 hours. By bringing engine production back to within Aston Martin, the promise was that Aston Martin would be able to produce small runs of higher performance variants' engines. This expanded engine capacity allowed the entry-level V8 Vantage sports car to enter production at the Gaydon factory in
