This was the very first Mercedes I ever owned, bought it for SWMBO about twenty years ago, it's so basic it didn't have a sun roof nor passenger side mirror .
I just finished a major overhaul of the engine and tranny plus up graded the AC to a Sanden 7 series compressor and larger, cross flow condenser sold by a member right here .
I have less than 200 miles on it and have begun driving it on the freeway , varying the speed all over the map from 40 ~ 70 MPH , I tend to be out in the wee hours of the morning when there's no other traffic to speak of .
As so many mention, this thing has so little power it's either comical or absurd and if one isn't fully aware could even be dangerous but oh, my
HOW DO I LOVE THIS CAR !!! 
.
I took the seat belts out and hand washed them so now they're floppy and smooth like a good quality silk tie, when you release the buckle they
zip back with a flourish like new again (my Foster boys often allowed them to get caught in the doors before) , I replaced all four door latch strikers with the good ones (W126 P/N superseded) so now all four doors close with delicious little clicks like a bank vault again .
I hope my buddy didn't toss out all the old parts, the engine was _really_ worn out from lack of oil changes by the original owner, a nice guy who didn't smoke and always garaged it but that carbon soot in the oil slowly and gently wears _everything_ out ~ you gotta see the cam chain tensioners and shoes, the chain was worn out even .
?! How the heck does the OIL PUMP get bent ?!??!!
.
Only 362,000 + miles, I'll never see a dime back out of this car, good thing I like it so much
