I went on a tour last year with Autobahn Adventures, and again this year. What I like the most about it is that you have the freedom to do what you want to do. They will let you know what is available in your area, but it is not like you are in a caravan, where you have to go where the group goes. You can see and do what is of interest to you. Because they limit the number of people, and make sure that all the parties are of roughly the same age and background, that definitely makes the interaction better, and easier. I also like the fact that Mark and Tina go with you on the trip. They are always available by either phone or text should you need them. Overall, this is a really unique experience, and very enjoyable!
