We've never seen one of these before -- but hey, there are a lot of microcars out there.
This 3-Wheel 1993 City-EL Targa was recently posted on CraigsList. It's got lots going for it -- new tires, good interior, windows, top, etc -- but the statement that it ran well in January, but had to be pushed into the corner of the garage sets off the lights and buzzers.
If you know anything about electrics it might be a good deal. Check out the Wikipedia page on the City-EL.
