Last year we went to Hart voor Auto's and Deutsche Autofest at the TT Circuit of Assen. There we saw a lot of sportscars attending the event. Many participants were also revving their cars. In this video you can listen to some awesome cars like a BRABUS 800 E63 S AMG, Akrapovic Golf 8 R, Novitec 812 Superfast, Widebody RS3, Aventador SVJ, 700HP S7 and many more!
