BenD is right, I'm just a hobbyist, and my work would be better
Some say that box modelling a face is the best way, but I tried the vertex/poly technique and like it, I posted my work at CGTalk and was told to use box modelling because my approach is too slow and box modelling should be quick and easy, which I am learning to do. But you can use that technique on cars, guns etc.
There are various tutorials on the internet, for the vertex/box modelling approach I used the Joan of Arc tutorial, google it, its a pretty famous tutorial, its directed at 3DS max, but isn't tool specific.
As for my box modelling I use a Cinema 4D specific pdf file, so it prolly wouldn't make sense sending it to you. (plus you don't want to download)
So my best bet for vertex faces and box bodies, I'd use the Joan of Arc tutorial, it helped me a lot, just do the tutorial repeatedly, and each time it will look better.
