Opening and closing the power trunk is easy, and loading your Louis Vuitton luggage through the large opening is no problem, thanks in part to the low liftover height. And if you just dropped by Trader Joe’s for some Two Buck Chuck and few bags of organic whatever, Mercedes provides twin drop-down hooks to ensure that your groceries don’t roll all over the cargo compartment. The trunk is richly finished, with a shallow underfloor storage tray. The only thing we can’t figure is why the sill is dressed in black plastic rather than a classy strip of aluminum.
