TAKING A ROAD TRIP IN A VINTAGE MERCEDES: “In 1977, the late David E. Davis, Jr., tested a 6.9 for this publication—back when it was the fastest sedan in the world. On his 4000-plus-mile journey, the A/C quit the team and a lower engine pulley worked itself loose. That car was a factory-fresh press vehicle. This is a 78,000-mile, 34-year-old example with a limited-production SOHC big-block, a Citroën-licensed hydropneumatic suspension system only ever used on this particular model, and a whole lot of vacuum lines in likely questionable shape.” Note the hopeful conclusion.
