Steve, Sorry to jump in your post but "Switchback" what is that Red 3 Wheeler on the back of your QQ ?, over here there are not so many variants of cars (possibly a Kit Car) like there are in the U.K., so I am lost - Thanks
It's a Grinnall Scorpion. You can buy them either factory or home built. The power train and transmission are from a BMW motorcycle. There are a few in Germany and many in the States, somewhere around 400 worldwide.
