The Uno III is apparently now for sale. However it helps if you have access to English pounds. Here is the sale offer and another short interesting video about the vehicle. It appears that the fellow who makes these things won a TV inventor contest (say whatever happened to those contests, I thought they were kind of neat) that provided him $1,500,000 for a 20% of his company to get his vehicle fully developed and on the road.
Here is a link to the ad and the video:

I really like the idea that it can fit into an elevator. That would be a real boon for an big city apartment dweller - provided you could sneak it past the management and into your apartment.
