One caveat about the 55 is that you will lose a great deal of cargo space over the standard MLs as the spare resides in that area instead of the undercarriage...as much as I wanted one, I need that room for my extensive music and soccer gear.

But I don't think most ML55 owners buy one to jaunt over to the nearby Home Depot, do they?
