I've been to quite a few dealerships and have noticed that not all Clarity's are created equal. Some drive very smooth while others are noisy. One Touring model had a low rumble sound at residential driving speeds and another had high rev sounds, as I accelerated beyond 30 mph. You'd think there would be a greater quality control and consistency. Any thoughts on this? Sometimes I leave a dealership feeling confident about buying the car and other times, I leave thinking maybe this is not the car for me.
