If the S500 was the Mercedes flagship car, then the S600 would be the mothership. This came with all the standard and optional amenities as the S500 (leather, wood, traction control, air suspension, etc.), but it boasted a much larger 6.0L V12 engine. This meant more power to carry around the two-ton plus vehicle. Some would argue this 400hp motor was overkill, but certain S-Class models weighed in excess of 5,000-lbs. Mercedes-Benz S600 parts are absolutely the finest, because the standards to which that car is built are the finest.
