Agree LX is quieter. I had driven several LC and LX when we were shopping for a car, and the LX seems to be quieter to me. Granted it was different year, different tires, different road condition etc, but LX for some reason felt smoother and quieter to me. Maybe AHC also plays a role here. Very small difffences, but noticeable to me, but not to my wife. If I have to choose two car, with same price and condition, I would have gotten the LX just for the quietness because it will be my wife's dd and our long distance vehicle.
