Its one-dealership history through the 170,000-mile service and subsequent crankshaft repairs gives this high-mile W221 clearer maintenance context than its odometer alone would provide. At 173,900 miles, it sits near the high end for this generation. The counterweight is the 2015 collision, deleted ABC system, active brake-pad warning with grooved rotors, and the gallery's documented body, lighting, and cabin damage.
