1979 is my guess. The W123 is revered for being one of the most reliable models of all-time and despite the fact that there was more than 2.4 million W123 models produced between 1975 and 1986, none remain quite as special as this.

1979 or earlier. I have a 1979 300D and was told you could also still buy a 240D in 1979.

Love that body style. To me, that is classic Mercedes design.

That car will also out last anything out there. The sun will explode before that car comes off the road.
