Picked up a GLC300 last year with this, grown to like it quite a bit. Douchnozzles driving like constipated grandparents on Xanax bother me less when I end up sitting through two lights because of them lack of interest in arriving this century.

The Merc has the equivalent of dropping the car out of gear on the highway when coasting (glide mode). Initially programmed the pre-set modes to disable the auto stop, then realized I was being stupid since I sit in start/go traffic a lot. Mileage went up noticeably.
