Here is another scooter that is up for sale at auction in Las Vegas. It is listed as a 1965 Heinkel Tourist. I believe it is a Tourist model 103 A2. These scooters are great, and I have always wanted one in the stable. There are actually quite a few of these things kicking around in the San Francsico area, despite their overall rarity in the US. That fact is probably a result of the US West Coast distributor for Heinkel being located in the area. However, total US sales for Heinkel was less than 400... though a quarter of that total was in the San Francisco area. Judging from the photo, this one was not originally sold in the US, but is a European import. I say that because the photo background just looks like it is in Europe, we don't normally do brickwork on the ground like that in the US.
The styling on them is just so great, they look like a jet-age hovercraft... something from outer-space. They must have been pretty crazy looking to 1950's eyes, but surely even more so today. Luckily for their owners, there is a huge following for them in their homeland of Germany, and just about every part you need to keep one going is currently available. When they are set up right, they are utterly rock solid scooters. I can attest to that fact because I followed a friend of mine on his while we did a grueling 1,000 mile ride over three days... and I was on a BMW motorcycle! Now, since I won't be in Las Vegas, who wants to sell me theirs?
