The W116 was introduced in 1973 with the new designation S-Class, S standing for Sonderklasse, or Special Class, as in, unless you are special, you can't afford this. A few decades later and many depreciated into the hands of folks who abused them, so it is nice to see one in excellent condition. The seller states that this is the original paint, and it wears European headlights and a nicely preserved beige MB-Tex interior.
This 280SE is powered by the M110, a 2.8 liter inline 6 pushing out 142 horsepower and 176 ft-lbs of torque into a 4-spd automatic transmission. It isn't t most powerful engine you could find in a 4000 lb luxury sedan from the 70s, but it is smooth and does a decent job.
