What kind of fuel did the car require? What was the cost? Was there a differential between German and Austria? Did you notice where the more reasonable price were (on or off Autobahn); in larger cities; in small towns, along secondary roads? Was there much of a difference?
Sorry for all the questions, but I believe I read that it cost the equivalent of $140 to fill the tank (about 16 gallons)! Tell me that isn't true.
