Probably the most important thing is a properly working fuel
distributor. Parts are getting VERY expensive.
Next is suspension -- that car used the old design suspension links
and they are likely dead if not replaced fairly recently. Not a huge
job, but they drive horribly until you get them all in. I need to
finish mine before it snows, the rear end is really squirrely. Very
nice handling when they are intact.
Front suspension ditto -- plan on ball joints if not done recently,
they are likely dead of old age. Upper strut mounts too, see if they
are not. Front swaybar bushing shrink and rattle, also the frame
mounts are a joke and break all the time if you have to drive on
rough pavement.
None of this is horribly difficult or expensive to do, but you do
want to factor it in.
ACC is a problem, quite a few of these cars have failed AC
evaporators, and that job is pure hell. Not really difficult, but
the rate book calls for 16 hours to do it. Blower replacement is
common, and a pain although you can get to it from the front.
Pushbutton units and sensors fail, resulting in erratic operation.
I've not successfully rebuilt a unit yet, although I may try since
the TE is getting really out of spec.
Early M013s suffered from excessive valve guide wear and failed cam
lobes, so be aware of that. Also known for a leak and the front
camshaft cover seal and weak head gaskets. Easy to fix, but again
you need to consider in the price. Not cheap for a shop.
If it's not been done, you will need to replace the idle control
valve hoses and the boot between throttle body and air flow sensor
horn -- these cause terrible running and throttle response problems.
A pain to do. Leaking injector seals are an issue, and leaks at the
sleeve for the injectors, often overlooked, also cause rough idle and
performance problems.
If it runs well and drives nicely, it's a great car (my brother and I
have four between us, plus a W126).

Looking at an 89 300e. I know nothing about the gassers and this
chassis.
What should I look for? What is too high for mileage?
Thanks, Mike
