My heart always comes back to the 1977 to 1980 pre turbo 123 chassis, (my
two
cents).
I've had 5 of them, 3 300D's and 2 300CD's. I would have to agree with you
on simplicity, no ALDA adjustment and no extra places for oil leaks such as
the turbo oil drain tubes. I say this as I'm about ready to plunge into a
1983 300SD. I'll let you know how I feel after owning a turbo car. The
only thing I don't like about the older W123's (doesn't apply to 240D's) is
the ACC servo. I would have preferred that all such cars had the manual ACC
systems which the 240D's were equipped.
