I was in Caborndale IL last weekend, and saw this Dymaxion in the hotel parking lot.
I didn't bother to look it up until after it was gone, but if I had I would have hung out to talk to the owner. I thought it was some sort of hyper mileage project car but it had antique car plates. Apparently this thing is about 80 years old, maybe one of three made. Had single rear wheel steering. Here's a link to the Dymaxion WIkipedia page
