Such an awesome story! Thanks for posting this.
Now you need to come back to Germany, rent a Porsche and go on one of their "Driving Experience" tours. Porsche plans everything for you, you just pick up a car and drive at your own speed to each destination. Plus they give you some freebies like luggage(at least they use too). Its something I have always wanted to go on.
