Driving on the Autobahn is quite the experience. I got to do that a few years ago, but it in an Opal Astra... I didn't get the speedometer to go quite as high as you. It was still fun though. My first experience on the Autobahn was when I was 16. I was an exchange student and had been the country for about 45 minutes before I was picked up by my friend and his father. We hopped in his BMW (5 series, I believe) and before I knew it, we were going 215kph (133.5 mph). They continued to have a calm conversation in the front as I held on for dear life. Willkommen in Deutschland!
