Took vehicle to dealer for vibration during v4-v8 cycle on SS camaro during speed of 50 to 70 mph. They could not replicate after two different people test drove it. Headquarters engineer say this is typical. Picked up vehicle from dealer and as expected vibration was again very noticeable. If I was aware that this was going to be a typical issue I would not have purchased a new Camaro. Also during the time at the dealership shut face on driver's side of bodyside was damaged. Garage manager took no responsibility for damage. I will not return to Preferred Chevy - GMC in GrandHaven for future repairs - oil changes and or purchase of a new vehicle as they do not stand behind there product.
