This is episode one of me finding out why my Mercedes W126 500SE does vibrate quite extreme at speeds over 120km/h (75mph). So I take the car on the German Autobahn. Join me to observe the vibration at various speeds. As it is a vibration, it is a bit tough to observe in a video, but I think you can see the vibrating steering wheel and hood ok. In following episode or episodes (not sure yet), we will take a closer look at tires, rims and will also have shock absorbers checked to really solve the issue.
