Thanks for the advice!
I used photoshop to first outline the car and get just the vehical itself in the image.
Then, I imported the image as the texture for a block proprotional to the image size.
Then, I used the the 'cut' tool, and [shift] clicked to make staight lines and outlined
all of the details of the car.
Lastly I make the wheels and suspension.
How do you recommend I create shadows and highlights?
