Wow, impressive
I am going to buy the one I am looking at only has 200K and engine was
replaced at 150K and rebuilt by an MB mechanic (have all history on the
car)..
Just need to get the injector pump adjusted and we should be good to go,
drive from Pensicola area to PA. had a full inspection and it passes my
standards.

My 73 220D has better than 800,000 miles on the clock.
Engine rebuilt once or twice since new per original
owner. Don't know the extent of the rebuild(s).
Maybe they fixed things in 1973.
