Interceptor insanity: This mad Jensen’s button gives it 3000hp

Duncan Davis still can’t believe his good fortune. He may not own the super-rare Jensen Interceptor beside which he is standing here, but he’s the chap who drives it.

“Its owner is my best friend,” he explains, “but he lives abroad so I look after it and get to drive it and his other cars to events such as today’s Goodwood Breakfast Club meet.” Duncan’s smile is as wide as the Jensen’s grille, and it quickly becomes apparent why.
