i have a 08 ml 350 with 1800 miles on it, at the red light i could feel the wheel and the seat vibrate, somtimes heavily. i put it in neutral but it only helps a little. my dad has a 02 lexus rx 300 with 50000 miles and you could not feel it at all. i also have a 01 mitsu eclipse with 90000 miles on it and i could feel it vibrate a little. i have been to the dealership 2 times and they said everything is fine, i don't want to go back without any new info
