Part 6: Filling in the Rest
So, we've managed to finish up most of the shell of our car. Now is the time to fill in all of the gaps and holes we still have in our car. Some of them are fairly simple to do, as with the spot pictured below. You can even see how I extruded the mufflers.

Now you will want to fill in all the holes. As shown above a few only require an extrusion to make it appear complete. Other places, such as the grille are a little different. Some vehicles have solid big grilles that can easily be modeled. However, other cars have very small detail. If your car has a lot of detail I suggest just using a texture when you start coloring your car. In this situation you just want to make the gap as flat and smooth as necessary so that the texture will look good when it is applied. If your car has a bulky grille, like the Camaro, it is easier to just model it.
I have filled in all of the gaps here.

Now is time to adjust the edges of our separate pieces. These pieces are the hood, the doors, and the trunk. Maybe you have more moving parts depending on how detailed you want to be. Typically, there is going to be a small gap that is around the edges of these pieces. If you connect the pieces you will not see them and your car will not look realistic in the end. To do this we begin to connect all of the edges to the rest of the car like we have been connecting all of the other pieces.
When all of the vertices are connected go into face mode and select all of the faces that are part of the hood. Do not select any more or less faces that what is to be the hood of your car. Once you have done this, press Y. By pressing Y, you have taken the selected area and separated it from the rest of the car. Now that we have done this, the vertices match up perfectly. There is literally zero distance between the vertices. Now all you have to do is make a gap. To do this scale the hood down until the gap looks right.

Now you can just do this same thing with the rest of the pieces. If you want to go through the rest of the car and do the rest of the lines and gaps you can. The more you do, the more realistic your car will become. Here, I have just done the doors, hood, and trunk. Depending on how good you are with texturing and materials, you may be able to create the illusion of gaps. Personally I think a gap will be more reliable and easier to deal with.
