People of Surrey, do you really need your Range Rovers? In order to answer this burning question, Jeremy, Richard and James overshoot Surrey by some margin and end up in Botswana where, armed with just three cheap, two wheel drive cars (and a massive film crew), they set out to cross the heart of Africa. Will they survive the treacherous ooze of the salt flats? Will they be eaten by lions and hippos in the awesome Okavango Delta? Will the Stig?s African cousin think Jeremy?s Lancia is rubbish? Will James drive into Zimbabwe by mistake? Will Richard leave his wife for the car he loves?
