Summary

Experts rate the 300 SD as one of the strongest cars ever built, with the OM617 engine renowned for its ability to travel millions of miles with proper maintenance. According to ProfessCars™ estimates, although it is not a fast car with a 0-100 km/h acceleration of 15.6 seconds, it offers a very comfortable and sufficient rotational movement (230 Nm) for its weight. Measured consumption (combined 10.1 L/100km) was revolutionary for a limousine of this size in the 1980s. The starting price in 1981 for this model on the US market was around $34,180 (approximately €33,200). Today, this model is considered an icon of Mercedes-Benz engineering, being sought after for its mechanical simplicity and low cost of operation.
