How did he make his millions? On holiday in Florida in the '70s, Madejski spotted a local car sales magazine which included photos of the merchandise. Inspired, he set up Thames Valley Trader, which advertised pretty much everything under the sun. This evolved into Auto Trader, a titillating read for the red-blooded car-loving man. Madejski's Hurst Publishing, including Auto Trader, sold for £174m in 1998, and he has since ploughed his money and energies into property, hotels and his Premier League team.
The secret of his success? A healthy lack of sentiment. As he says of his football club: 'If there is a billionaire who wants a nice accessory down the M4, then come and talk to me.'
