Though we may all dream of owning a 6.9, the 300SEL 6.3 was the original German Q-ship. This $55,000 sedan's 6.3-liter V8 produced 250 horsepower, 369 ft-lbs of torque, and could propel the nearly 4,000-pound hunk of beautiful metal to 60 mph in 6.5 seconds. That's pretty good today and outrageous in 1967. We were therefore delighted to see one from the Mercedes-Benz Classic Center gracing the floor of the Chicago Auto Show.
