Looking for drawing books.

[Enigma]

I'm trying to improve my drawing skills as I haven't been drawing much in the past few years. I've bought a decent book on how to draw a person (actually it is a book on how to draw american\manga fusion style people but it was the only one that I could find that offers a simplistic way to draw faces, etc...). But right now I am looking for books that offer a decent, simplistic way to draw vehicles, robots, mechs. Anyone know of any?

While not exactly what you are looking for, I found the Dynamic Anatomy series of books extremely helpful for myself when I was younger. As for drawing vehicles, robots and mechs... I would suggest any book on perspective as they basically break down into straight lines all going in one direction to one point. Sorry that is all I can offer, I didn't use to many resources other than just drawing what I saw when I was younger.
