Paul Radisich, one of the pre-season favourites, was Tarquini's first challenger, the New Zealander attacking fiercely from the second row of the grid in his Mondeo to snatch the lead on the Wiltshire track. But Radisich soon fell back among his pursuers and he later spun further down the order after clashing with Giampiero Simoni, Tarquini's Alfa Romeo team-mate.
John Cleland, whose natural aggression occasionally leads him into making rash moves, chased Tarquini hard all the way to the chequered flag in his Vauxhall Cavalier. Following the race, though, the British driver said he felt he had little hope of passing the Italian. Simoni, meanwhile, was third for Alfa, ahead of the reigning champion, Jo Winkelhock, in the lead BMW 318i.
