Wow, the Autobahn? That's really cool! When the first generation late model Shelby GT500 came out, Ford had a commercial where an American owner brought his supercharged 5.4 to Germany not because Germany didn't have a car he liked but because the USA didn't have a speed limit he liked. I bet driving your 5.0 on the Autobahn would be a blast! What kind of gas mileage do you get on the Autobahn? 15mpg?
