how do you create indentations for the hood and doors. I've seen several tutorials for this on 3d max, and other programs. I'm in the upper beginner skill level.

Could you please be more specific? Do you want to separate doors an hood from the body? Or do yo want to fake this?

if you want to explain both ways that would be great, but i was looking to fake it

Faked door.

That's how it works in a perfect world:

A) Suppose grey surface is a body of a car and red line is the outline of your door, hood, or whatever.
B) Create a pipe with diameter equal to the gap between the bod and the hood using "Pipe" command
C) Using "Split" command subtract the pipe from the surface and delete the pipe.
D) Select the surface (yellow color) that is created by subtraction.
E) Offset the surface inside the body using "OffsetSrf" command, the resulting new surface is shown in blue color.
F) Delete the yellow surface.
G) Create two surfaces that connect the body and the door to the newly created surface (all shown in blue color). This can be, for example, done by "Loft" or "Sweep2" commands.
H) Rendered version of picture G.
I) Join blue surfaces to the grey surfaces using "Join" command.
J) Using "FilletEdge" command select the lines marked by yellow color, and using a small radius create smooth edges.
K) The final result

This is a simplified procedure. In real situation it may not work directly, but that's the ideology; you may have to modify some of the steps using other commands. For example, to smoothen the edges you may need to make a pipe on the edge and cut it away. Also, you may need to use simple lines (surfaces) rather than polylines (polysurfaces) in some cases. That's something I can't say, it differs from case to case.

To actually cut the door it's another story.
