At least driing in the forward direction the mirrow will give in to
obstacles. It is mounted with a spring system and with some force you
can alignethe mirror with the window.

If it the springs are hard and the mirror going back to the standard
position the mounting will be ok.

The mirror housing is designed to swing in toward the car when a force hits
it coming from the front toward the back of the car (opposite of what you
described).  I don't know that it is supposed to swing the other way though,
so you might have broken something.  Swing the mirror in the correct
direction and take a look at the innards.  Did it just break a spring?  You
could go to a junkyard and pick up the parts you need off a wrecked car.  If
you search some of the Mercedes websites with message boards, you should
find complete directions on how to take of the cover/shell to access the
innards and unscrew them from the body of the car for full replacement.  I
think it is about $500 if you want the dealer to replace the parts and
install them.

If the mirror is still in the correct place, then I wouldn't worry about it
at all.. Give it a wiggle... make sure it is still tight on the car.

It is hard to break those mirror off the car... bolted in. As for the give,
newer cars allows the mirror to be moved both way to a certain extent.

The mirror housing does swivel both directions, though more space to
flip rearward than forward.

I don't understand what you mean by "hanging there, in the correct
position".  Its correct position is attaching to the door firmly, so
what is hanging?  Can you move the whole housing freely without much
force?  Then either the hinge or the spring holders are broken.  The
hinge has its own part number but MB only sells the entire assembly
(i.e. the whole mirror minus the glass and the shell) which is something
like three hundred dollars.

Ours (96 C280) was broken on the driver side.  Luckily I was able to
attach it back snugly.  It is not as firm as before and hitting anything
may break it again but it stays there (for the last 1-2 years).

The shell has three tabs (near the door side).  Bent the mirror forward
so you can see them.  Once they are disengaged, the shell can slide out.
 The hinge has double frame (so it can flip both directions).  See if
any part is broken.  The spring goes thru the middle.  You need a strong
hook to deattch/attach the spring.  I used the brake shoes tool.

If the mirror does need replacement, a used one is not easy to find.
However, color isn't important since the shell can reuse your existing
one.  If you have plenty time, a left side mirror shares about half the
parts (e.g. the hinge) though I do mean "plenty" of time to work on.

Good luck
