Vanderhall?

[Valkorado]

These look fun, manufactured out of Provo, UT.  I don't recall seeing them out and about, but have seen lots of the Polaris Slingshots.  I think I prefer the styling of these.

Doesn't matter, I'll never own either.  But a day rental would probably be fun!

I guess most states register the Vanderhalls as motorcycles.

Saw one on the highway in Vegas a few years ago. They have a retro look to them. At the time I thought it was an old machine. I learned later that not to be the case. It did look pretty tight for two people though.

A shop near me had one on their floor last year. It was interesting but not very appealing. Way out to fly budget too.
