   The only weapons that _reliably_ (over 75%) penetrated a car door was a .50
   caliber sniper rifle and shotgun slugs (military combat shotgun issue.

I strived mightily to stay out of this one . . . BUT!

Comparing a .50 "Sniper" round (I assume ".50 BMG", and not ".50
minnie ball") with a (presumably) 12ga slug is like comparing (or
lumping together) a bicycle with an UrQuattro.

A 12ga slug has only slightly more "penetration" than a well-swung
baseball bat or tire iron (which is not to say it doesn't pack a hell
of a whallop!), whereas the .50BMG traces its origin to an anti-tank
round, with a target penetration of (as I recall) about 4 *inches* of
armor steel (a 12ga slug will just flatten out on the armor plate,
probably severly smearing any paint job on the armor plate). A .308
(7.62mm NATO) will penetrate almost .5 inch steel plate at 200yds,
while a .223 (5.56mm NATO) puts a nice dimple in that same plate,
turning to "dust" in the process, and a 12ga slug will be lucky to
make it that far and still be able to hit anything reliably.  Any
"regular" handgun load (.38, .357, 9mm, .45) will just flatten out on
that same plate, hardly even denting it. (I am referring to "standard"
jacketed lead core bullets here, not harded tungsten carbide
penetrators; KTW, and the like; SS-109 "steel-tip" .223/5.56mm for
example holds together and "penetrates" much better, but is still no
match for the brute force of a standard .308/7.62mm...)

A .38Spcl 200g round-nose lead bullet, fired from a 2inch "snubbie"
at "point blank" (in this context, means a few feet) stands about
a 50/50 chance of penetrating standard car window safety glass.
A 9mm is 100% effective in the same test. Ditto a .357.

The "skin" of a car door is no impediment to a 9mm, nor a .357
(.45 is not nearly as effective, a .38 even less so); however a
side-impact steel beam will probably stop a .308 rifle bullet.
It all depends on where you try to penetrate the door. Tell me
what you want to prove, and I'll come up with a tailored bench-
mark to prove it... There's a LOT of variation in the RealWorld.

Depending on a car door for cover is pure stupidity. As is (for some
more Hollywood realism) hiding behind a normal wall, or a door, or a
table. Ditto the digging out of a "spent slug" from a plaster wall
coating (unless it just happened to be slowed down by a body or two
first...). Ditto the idea that a body hit with a bullet is picked up
and flung through the nearest wall (or, preferably, plate glass
window).  Depending on an entire car is only slightly less stupid,
although that at least tends to hide the actual "target" behind the
car. As to an engine block, there are some very thin portions that
would provide little challenge to a .357 at just the right angle;
however *in general* the concept of a .357 plowing through an entire
engine block is silly (which is not to say it won't put a nice hole or
crack in the block, effectively disabling the engine). Most likely,
it'll just bounce off in an unpredictable direction. Even a .50BMG
won't be able to penetrate a "whole car" if you just happen to align
just right with a nice steel drive shaft...

Oh good, it's late enough to go home now . . .
