Gauntlett bought a 10% stake in Aston Martin for £500,000 via Pace Petroleum in 1980, with Tim Hearley of CH Industrials taking a similar share. Pace and CHI took over as joint 50/50 owners at the beginning of 1981, with Gauntlett as executive chairman. Gauntlett also led the sales team, and after some development and a lot of publicity when it became the world's fastest 4-seater production car, was able to sell with success the Aston Martin Lagonda into the Persian Gulf states, particularly Oman, Kuwait and Qatar.
