Thanks for the comment emceeONE! I also used to be really jealous of concept/product design artists, but about 2 months ago learned all the secrets. I still have a long way to go, but everything you need to know is here:
Scott Robertson's videos:http://www.thegnomonworkshop.com/store/category/110/Scott-Robertson
Basic Perspective Form Drawing
How to Draw Cars
How to Draw Airplanes
How to Draw Hovercraft
And this product design book on drawing:http://www.amazon.com/Sketching-Basics-Roselien-Steur/dp/9063692536
Those are the two sources that cured me of machine envy, and it's something you can pick up in about 2 months if you study Scott Robertson's videos, and the Steur and Eissen product design book.
