After liking the Yeti Ioriginallybought to run my Great Dane around in so much I sold my Merc C250 cdi Est and bought a new Yeti. Although the "Stop Start" on my 2 year old Greenline hardly worked at all? the new one however works fine and even in the winter itfunctionsabout 75% of the time and the new Greenline does about 5 MPG more for some reason??
