The Regent Street Motor Show is the largest free motor show in the UK. Over 300 vehicles will be in attendance - ranging from classic automobiles of the Victorian age right up to the very latest 'super' cars of today - on display from Oxford Circus to Piccadilly Circus. That's 125 years of motoring history displayed along the street. The entire street will be closed to traffic from 10:30am - 4pm, giving you the chance to get up close and personal with your favourite motors.
