Dorothy - 1963 Rolls-Royce Silver Cloud III

McLaren F1 team manager Alastair Caldwell's ‘rally car’! He once drove it 18,000 miles in a few weeks in the US with his 94-year-old mum as navigator (earning 5th overall, 1st in class) and gaining her a Guinness World Record.

It's done - Berlin to Moscow. Full length of China. TransAm rally Road to Mandalay through Malaysia, Thailand, Sri Lanka and Burma… and oh so much more.

The car got him banned from the BRDC, after it ended up on track hours after an F1 race at Silverstone. The horn's never worked, so it's been a silent wonder.

This might not be the most valuable Rolls in the world, but it might be the most interesting. It’s in fabulous condition, and you can own and drive it.
