Welcome, Mercedes W123 Owners

When asked to picture the quintessential “old Benz,” the US market will generally name the W123-chassis and its many variants. These models shared a good deal with the outgoing W114 and W115 in an updated design package, notable by its trademark rounded headlight bulbs now floating in a horizontal housing.

Just as with their predecessor, the W123 models provided supple and luxurious interior packages with a relaxed ride and a dependable powerplant; the complacent diesel engines in these models have been frequently repurposed to run on biodiesel fuel through the years due to their versatility. The chassis code can easily be used to identify the body style (“W” noting sedan models, “S” noting wagon variants, and “C” being the two-door coupe offerings).

Additionally, the badging on the rear of these vehicles is easily-deciphered; following the numerical badging to note the engine displacement, body style was noted by a “T” to acknowledge wagon variants and “C” for coupe models, followed by either a “D” for diesel, or “E” for “Einspritzung,” or fuel-injection.
