Since, it seems clear that my poor 1981 300SD is a lost cause, I'm
looking to purchase a 300SD or 300SDL within, hopefully, a few years
(Depending on how much I'm able to save, I'm just a college student).
As such, I would like to know what to look for in the old 300SDs and
300SDLs. In particular I'm curious to (In no particular order):
* Which engine is more reliable/durable? The 5-cylinders or the
* What years (Though I suspect they're all fine and I realize this is
very open-ended) are generally viewed to be the high points of each
* What is are the _major_ differences between the 300SDs and 300SDLs
and what would persuade someone to go for one over the other?
* What is the rate of depreciation for these models?
* Are there any options on the cars I should particularly go after if
I'm only looking for the W126 chassis models from the early to mid
1980s when the construction seems a bit stronger (Though if my
assumption is wrong, please let me know!).
Also, some general 300SD/300SDL/W126 questions:
* What are the headlight wipers for? I have never understood their
* Does anyone know where I can find some good cup holders for the car?
My family once had the kind that one would hang onto the door, but
they've long since broke and/or disappeared.
* Just how long can Daimler-Benz diesel engines go with proper care?

As the years crept on, more sophisticated features were added, but in
my opinion, nothing earth shattering. Perhaps the biggest advance was
anti-lock brakes that came with the SDL
SDL had six cylinder engine, longer wheelbase, 15 inch wheels
standard, and anti-lock brakes (tho I don't know if the very first
SDL's did. The SD had a 5 cylinder all iron engine, 14 inch wheels
(15 inch aftermarkets are available).
The SD's are now so depreciated it is not worth worrying over, and the
SDL is almost in the same boat.
Condition, mechanical structural, and cosmetic, are more important
than options at this point in time.

Probably longer than you will be interested in the car, or its body
will hold up.
Once upon a time, the alternator in my 1983 300SD gave out. I was
outside of Harrisburg, PA. I drove to Pittsburgh, fueled the car and
stayed overnight in a motel.
Next day, I started the car, fueled up and drove to Chicago, being
careful to never turn the engine off and to not use anything electrical;
like radio; air; blower; windows. By the time I got home the electrical
system was flat. I measured 6.8 volts across the battery.
But I got home! The diesel and transmission didn't need anything
electrical, like ignition or fuel pumps to keep going.
The wipers on the headlights, are mandatory equipment (by law) in Sweden,
Norway etc. The reason they are there is so you can clear they headlight
(often). The wipers only work when your headlights are on. Every time you
squirt cleaner on your windshield (head lights on), the headlights would
also squirt cleaning fluid and the small wipers would come on.
Up there it's winter at least six to seven months a year. People didn't go
out clean their headlights after awhile
Hope this answers your question.
