You probably heard that on the German Autobahn there is a section where there isn't any speed limit. If you haven't heard of it play Need for Speed, and see how it's like. It won't replace the real thing but it's a start.
Not any kind of car can reach these speeds. This guy has a tuned up BMW M6M capable of getting to 200mph, and it even seems that the tuned up BMW could do more if it had the space. Anyway, enjoy this guy's amazing tune up BMW.
