I inherited my 1979 280CE from my grandparents, its been in the family since 1990-1991, looking through the old records it looks like between 1990-2013 it has had 3 servos installed, two vacuum pods, and one cracked vacuum line near the battery tray replaced in that time span.

As for now i plan to keep my original system to keep it original, i do not ever plan to sell this car.
