door locks

I have just aquired a 1975 mercedes 300D. I have been looking for awhile for a car like this and it came along. Straight body, no rust, needs lots of little stuff 238k. The biggest problem is the rear door locks are inoperable. I have read thru the forums and understand about checking the vacuum source etc.. and will do that.
1. How is the system supposed to work? never owned one of these cars before
2. My trunk opens (with difficultly) with the key and fuel lid just opens, are these separate from the doors. Only the rear doors don't work, are they the only doors on vacuum?
3. I cannot manually unlock either rear door, is this normal with a vacuum failure?

I paid $1600 for the car, does that seem reasonable?
I would appreciate any advise or tips, my wife and I want to keep and fix it up, keep it original.

Thanks in advance. Vance

Congrats on the cool Benz. If it starts, runs and drives good $1600 is a good price (even better with no rust). Look very carefully for rust, it is very sneaky. I'm working on one now that looks alot like yours.
