The Moon Buggy - Diamonds are Forever
The Moon Buggy in Diamonds are Forever is one of the more zany Bond cars. 007, being played by Sean Connery at the time, used it to escape Willard Whyte's Techtronic Labs in the Nevada Desert.
The Buggy was notoriously, well, buggy, as the vehicle would often lose a wheel during filming. In fact, this can be seen in the film, with a rogue wheel rolling towards the camera.
The buggy was left to rot in a field in Kent until The International James Bond Fan Club found it, and lovingly restored it. Once restoration was complete, the club tried to flog it at Christie's auction, where no one wanted it, so they turned to eBay, where again, no one wanted it.
Finally, it found a resting place in Planet Hollywood Las Vegas, bought at a substantially reduced price.
