A book I purchased today
Drawing Realistic Textures in Pencil.
I think this book would be helpfull for rendering cars.
Remember check it out first before you buy it.
This book is not a absolute beginers book. It assumes you can do acurate line drawings already.
Just so you know the people at amazon.com all gave it 5 stars.

If you want to see some amazing stuff that makes my graphite car look like a coloring book work check this out.
It is not a car but if the person can do that with a portrait for sure they can do a car and make it look like a black and white photo.

That is not a photo.
I am still amazed everytime I see it.
That artist has graphite mastery, no it's wizardry.
