Choose a Mercedes-Benz S-Class from any generation since it appeared on the scene in 1972, and you’ll find a car that was the cutting edge of technology at the time it was introduced. With heritage spanning way back to 1954’s ‘Ponton’, the S-Class continues to represent the best that Mercedes-Benz’ boffins can muster. This 1990 Mercedes-Benz 300SEL Sedan up for sale with us right now represents the later years of the sturdy 126-series. Being a long wheelbase variant as denoted by the L in its name, it’s a V126 chassis code. The current owner reports some recent maintenance, and we see that the odometer indicates 114,031 miles at the time of photographing this car for sale.
