Tonight, Richard Hammond goes crazy road-testing the new German sports car, the Veritas, while Jeremy Clarkson and James May invade Greenham Common airbase to ask if the Communists ever made a good car. Jeremy also conducts an almost ridiculously thorough road test of the new Ford Fiesta, plus (and the reason why we'll be watching) mop-haired London mayor Boris Johnson is the Star in a Reasonably Priced Car. Following at 9.00pm is the second installment of Louis Theroux: Law and Disorder in Johannesburg. The journalist concludes his investigation of crime-ridden locations by travelling to South Africa's largest city, where some residents rely on private security firms for protection.
