James Hull

James Hull is a British dentist and entrepreneur, who owned UK's largest and one of the world's biggest private car collections. After private equity firm Hutton Collins bought a 40% stake in the business in 2006, valuing it at about £90m, Hull and two fellow directors stepped down from the business's board in 2008 after the group made a loss of £8.7M. Irish businessman Emmet O Neill's Smiles dentistry group bought JHA in late 2012.

Personal life Hull, who lives in Knightsbridge, west London, has suffered from cancer three times. He enjoys playing cricket and tennis. In July 2014 his collection was sold to Jaguar Land Rover for an undisclosed sum. Sixteen of the cars were put on show at Heritage Motor Centre, Gaydon, Warwickshire from November 2014.
