Hey Richard,
He did more than just drive up Ben Nevis in a Discovery.
Apparently, after proving that it was infact possible to drive a Land Rover Discovery all the way to the top of Ben Nevis; he stepped out of the vehicle, cameras stopped filming and he jumped into a helicopter to return to London.
Sometime later it was realized that he still had the keys to the Disco in his pocket. and the car was still locked up on top of the mountain.
Talk about a dillberry!
But still nothing beats his Range Rover Sport vs Challenger Tank segment.....BRILLIANT!....why can't we see more TV like that.
