In 1989 Sears raced for Aston Martin in the World Sports Car Championship and Le Mans.

In 1990 Sears finished third at Le Mans in a Porsche 962 with Tiff Needell and Anthony Reid.

His racing teams under David Sears Motorsport and Super Nova have won 16 Championships in 26 years and produced more than 20 Formula One drivers, including Jan Magnussen, Taki Inoue, Ricardo Zonta, Juan Pablo Montoya, Mark Webber and Sebastian Bourdais.

The remnants of that empire and some of the best prime retail sites in Great Britain are now owned by Philip Green and his company Arcadia for Topshop and BHS.

Sears has also been involved as a director of Thunderball, a mining company in West Africa and more recently has helped Dr. Doug Linman create the MQ Corporation in the US and UK to launch Solar Liquid Power as a new form of green energy.
