the best diesel engine of the 70s-80s
hello guys, I'm new on this forum, but I love old mercs, especially diesel ones, which are known to be very reliable; the only problem is that I can't find out which, between the om615, 616 and 617 (non turbo), will last longer without major problems; so, if I had to pick between the 200/220d, the 240d and the 300d, which one should I choose? thanks in advance
