Steve, thanks for adding those links!!! The car I spoke about was indeed Leno's '29 Speed Six... I had the year wrong by a couple, but that's certainly the exact same car.
Here's another better link of the Speed Six, including a good test drive with Leno:
'29 Bentley Speed SixIn the video, Leno spoke about the 'fear' that would be incited when seeing his Speed Six appear in one's rearview mirror... that is EXACTLY what happened with me, as he menaced me and my poor Miata! The thrill of seeing that car driving, and then close-up-in-person, was incomparable.
I don't doubt that the Morgan 3 Wheeler will provide the same sort of driving thrill, in a modern maintenance-free compact package.
