This model had the Chrysler designed climate control servo. They are hard to
keep running unless you get an aluminum one from Performance Analysis. Many
parts are getting expensive for these cars.

I've owned an '80 300SD since new, fine car, comfortable to ride in,
great visibility and simple enough for a DIY owner to maintain and
repair.

Rust and the climate control are the '78 - '80 116's problems. Rust is
obvious, either it's rusty or not. The climate control is very
complicated and expensive to repair so as these cars lose value some
owners try DIY repairs which only make things worse. So if the climate
control is busted don't let someone tell you "Oh a new fuse will fix
that." The cost to make it work could be as much as you're about to pay
for the whole car!

The engine makes 110 HP and is good for 250K miles if reasonably
maintained. It should have its oil changed every 5K miles and its valves
adjusted every 15K miles. A diesel's internal condition can be checked
by a compression test, a worn engine will be difficult to start in cold
weather so have the compression checked if that's a concern.

Most of the cars that you'll see are nearly over the hill - shabby
interiors and lots of miles - be patient if you want a good quality car,
they DO appear from time to time and if that's what you want go for it.
I wouldn't ignore the '81 to '85 300SD, if only to avoid the older car's
complex climate control, otherwise same size and drive train but more
modern body.

The climate control system is not that complicated. It's just a poorly
designed system with a plastic servo with electrical switches, a motor and
water valve. Usually the housing containing the water valve breaks but I've
had the geartrain in the upper portion of the servo break also. George Murphy
at performance analysis has been selling rebuilt servos with a new aluminum
water valve housing. I've been using one of these in my 1980 300CD for years
but I've still had to replace the upper part of the servo another time or two.
I have lots of spare parts from all the servos I've purchased through the
years.

Have you considered buying a 126 body 300SD instead of a 116?

The turbocharged diesel engine in the 300SD produces 120HP.
