Mercedes produced the W123 series of full size cars for model years 1976 through 1986. The W123 models replaced the W114 range and surpassed that series to become the most successful Benz ever with nearly three million over its ten year production run. The wagon version of this line, the S123, was first factory-built Mercedes-Benz Estate as previous versions were custom-built by external coach builders, such as Binz.
While early versions of the S123 featured a non-turbo four-cylinder diesel, American consumers were not sold on the idea of a heavy wagon with only 77 hp. Consequently, in 1981 M-B introduced the famed OM617 inline five cylinder turbo diesel. This engine is considered to be one of the most reliable engines ever produced with engines often reaching over half a million miles without being rebuilt and is one of the key reasons for Mercedes’ popularity in North America in the 1980s, as it was powerful and reliable compared to other automotive diesels of the time.
The 301K mile Tan-Over-Tan 1984 300TD presented here appears to be a very well sorted example. As mentioned earlier, the high mileage should not deter buyers as this engine has a lot of life left in it. The items the seller replaced under his ownership are too numerous to list here (refer to his ad) however two notable changes include the addition of leather power and heated front seats from a ’91 420SEL and a matte finish plasti-dip paint job similar to the car’s original color. The seller states the car is rust free and judging on the extensive pictures provided, we have no reason to doubt that.
