I am currently own a Mercedes 79 300SD and like most Mercedes enthusiast get the yern for more. I am looking at a 80 450 SEL very clean except at this writing I do not know if it runs, or the condition of the engine.
I may be able to pick it up cheap,<($600.00) but I would like to know what problems they had. The car has 133K on it but it does not look that way. What would be considered a fair price, or should I run the other direction. I am a very experienced mech, so I am not really afraid of too much except big expensive things like an engine or trans. The engine looked clean except some oil around the filler. This could be blowby, or someone missed the filler cap.
