We saw many of them on our trip to Germany in 2003. They're so small & cute you just want to take one and stuff it in your wallet! (And now I see it was partly designed by the makers of Swatch watches, which explains a whole heck of a lot.)
I have no desire to personally own one (I have enough problems stuffing my frame and my stuff into my Corolla), but given the congestion and parking problems in many cities, an ultra-compact car that makes the Beetle look like an SUV may be just the thing many people need.
