We used to have a Thing when I was younger, it was actually fun to drive, and would places a Jeep couldn't get to. The front window folded flat, the doors could be removed, and you could hose it out when you were done. It was also extremely tough and great for towing behind the motorhome. The side curtain thing isn't that big of deal, unless someone had knotted up their bag and it was pouring down rain! They slip in and are done, nothing to them. I'd have another in a minute, assuming you can find one. People tend to keep them, and they are fairly rare.
Beetle goodness in Klublewagon package, what's not to like!
