 Nice car to drive. Terrible car to operate! Nav. and entertainment system is old technology--small screen and tedious to operate. Must have the radio on to get backup camera. Back up camera points downward and wording on screen blocks view. Clump of levers on left side of steering wheel and nothing on right side. USB port at bottom of console compartment. Temperature controls too far down in center stack. Door lock knob protrudes too far up (hit funny bone too many times at drive through window). Terrible foot room in back seat. Humming noise after shutting off engine. Lag in engine during initial acceleration. On high speed, wipers don't move fast enough to get rid of heavy rain. Car chews up shoulders on front tires. Imitation leather is actually nice. Last Mercedes I'll ever lease/buy.
