Hi, as the title suggests, my car vibrates noticeably at speeds of up and over 120 kmh or 70 mph. Previous tires were re balanced but the vibration could still be felt. New tires were installed and balanced and the vibration is still present. It can be felt throughout the cabin, from the passengers as well. The steering wheel also vibrates. I know that there could a lot od problems, what can i expect? (Mechanic says that driving components are good) Bent wheel? Alignment? Car is 2009 c207 e class coupe with om642 v6 diesel engine
