Where did all the space go in the 164? It is larger on the outside than a 163 and smaller on the inside. I would have expected a unit body to have more interior space for the same exterior size. By MBâ€™s own numbers it has less cargo space. I have amazed more than a few folk by putting 7 adults in a ML and not having any knees or heads brushing anything (didnâ€™t say it wasnâ€™t snug). This is in a vehicle the same length as a Cavalier (and weighs twice as much). The 164 looks good, the interior a big improvement but what happened to the Tardis factor? (if you are clueless watch Doctor Who). Did they screw it up on purpose so that we would pay even more for a larger SUV that would have the same capacity as the 163?
