I slammed the brakes to check on what I thought was a 240D for sale on the side of the road. Upon forther inspection the identification badge on the trunk lid-----250-----and nothing else????? I called the guy selling it and he said it was a 1981 6cyl inline gasser. Everything else about the car screams 240D. W123 chassis, manual A/C, manual windows, painted hubcaps, banana yellow version of my china blue 240D. Trying to do research now, the guy is asking $1500. with no A/C. Says everything else works fine. Problem is I'm trying to figure out the validity of this "250" MB. Never heard of it. Anybody ever heard of these?
