IIRC the 501CM has a better (larger and smoother action) reflex mirror.

Ding dong, the Witch is dead. Which Witch? The Wicked Witch!
I think the major difference between the two is that the 501CM has the
"gliding mirror system" (GMS).
In the previous models, vignetting (on the focussing screen only, not on the
film) would occur with anything longer than a 100mm lens. This created a
minor inconvenience when composing a shot with a longer lens (you had to
guess-timate a little how much was missing from the top of the focussing
screen that would, in fact, appear on the film).
This limitation was a result of the amount of available space that the
mirror had to work in. A longer mirror would hit the rear lens element as
it moved up. The solution incorporated into the 501CM was to put in a
longer mirror that would glide rearward (slightly) before raising up.
If I remember correctly, the 501C did not have GMS. It started with the
501CM.
There may be other differences, but the newer cameras are too expensive for
me, so my experience with them is limited.

The slight vignetting at the top of the focussing screen doesn't bother me
any. Clearly it wasn't enough of a problem to affect my camera purchase
decisions.
The 500C does not have a user-changeable focussing screen. The 500CM does.
(The "M" means "modified" from the original design). The CM's were made
beginning in 1971, but in 1970 they made the 500C with the changeable screen
but did not yet rename the camera. This has come to be known as the
"transitional body," i.e., old name, new feature.
My 500C has a split-screen focus that I like, but I don't know if it was the
original screen. The original screens were supposedly not very bright.
When people said this, I was always confused because mine seemed fine. I
supposed that my screen may have been changed along the way. When I got my
EL/M, though, which came with a bright-screen, I couldn't believe my eyes.
It's so bright you hardly have to use the magnifier in the WLF to focus.
Incredible.
The purpose of all this is to say that you should only buy a 500C if you get
a super deal. Otherwise, spend the extra $150 (on the used market) and get
the CM so you can quickly and easily change out your screen (without sending
it to Hasselblad). If you can get a 500C that already has a bright-screen,
then buy it and don't look back. In practice, I don't think many people
swap their focussing screens in and out very much.
I don't know that much, if anything, changed from the 500CM to the 501C.
Someone else will have to fill in this blank for you, but I think the 501C
was just a successor.
As an aside, I love my EL/M. It is a 500CM with an electric motor attached.
No hand cranking after each shot. Sounds like more bother than it's worth,
but it's actually quite nice. I prefer it. The predecessor was the EL,
which was a 500C with an electric motor. They, too, had "transition" bodies
in 1970/71.
If you've got the money, get a 501CM. If you're a cheapskate, like me, get
a 500CM. If you like convenience, get an electric body (they're only about
$50 more than their non-motorized counterparts on the used market) then post
back here and I'll tell you how to make it run on a 9V alkaline battery
instead of the NiCads.

Please observe that 500C is older than 500CM. While it is perfectly
capable, its screen is not changeable easily. Perhaps you should consider
500CM, 501C, or 501CM.

The screen in your 500 C must indeed have been changed. The original screen
had no focussing aids at all.

Good advice.

The 500 C/M was continued (under different names: first as 500 C/M, later as
"Classic") unchanged when the 'third generation' bodies (503 CX, etc) were
introduced. It was discontinued in 1994 when the 501 C was introduced.
The 501 C no longer had the "camera released"-indicator on the right side,
it no longer had a detachable winding crank, it had a new style release
button (no longer incorporating the 'T'-lock), it had the new style tripod
attachment plate and support ridges, and it can take the (useless) rear body
film masks.
It was sold in black trim only, and only as part of a complete set,
incorporating an A12 film back and the new-C 80 mm Planar lens.

Apropos upgrades: the only upgrade possible is buying the newer body ;-)
And beware: don't just say 501. There are two different 501 Hasselblad
bodies!
The 501 C offers no, or very little (non that would concern me), advantage
over a 500 C/M.
The 501 CM does have the better mirror-arangement, making quite a difference
(though it's the only real difference, and perhaps in itself not worth the
extra expense).
How about a nice used 503 CW?
You'll get all the 500 C/M and 501 C or CM cameras offer (including the
better mirror arrangement), plus TTL-flash metering, plus the possibility to
add a motor wind.
