CHALLENGE: May and Hammond search for the best convertible for a town with the least owned • Can you parachute into a moving car?

James finds out if it is possible to parachute into a moving car. Jeremy drives the new Jaguar X Type estate and on the Isle of Lewis and Harris - the place in the U.K. with the lowest number of cabriolet owners per-head - Richard and James test a range of cabriolets: the Mini Cabrio, Vauxhall Tigra, Mercedes SLK and the Audi S4.

Some "simple, softop sports cars" are also driven by Richard: the Mercedes SL600, Mazda MX5 and the Fiat Barchetta.

The distance between Resolute in northern Canada and the magnetic North Pole at Ellef Ringnes Island is 450 miles. It's a journey across sea ice and unforgiving mountainous terrain where temperatures can drop to minus 65ºC - a temperature at which exposed skin can freeze in less than 30 seconds. Only fools would attempt such a journey. So Jeremy and James are attempting to do it in the now legendary Toyota Hilux and Richard hopes to make it on a sled pulled by ten Canadian Inuit dogs. Watch the complaints from environmentalists roll in.
