When taking photos, the first 2 hours and the last 2 hours of the day can really make a difference due to light direction and intensity.  Car angles and curves can hide shadows and bring them to light as well as cause over exposure that can blur images when taken in full sun.  So best to wait till the afternoon or in overcast conditions. 

Taking photos at an angle centered on the front center windshield or front tire give the car a 3D appearance when on a 2D flat surface.  (PRO TIP) Once you have centered the your photo turn the front wheel in the opposite direction this really brings things to life!

Try to avoid grass when possible.  The pigments in the grass even when cut can show up on the wheels and paint causing your 10K paint job to look greener.  Also even blades of grass on the tires can cause blurry image translations even on the best of cameras not to mention it hinders the way we can make the car "float" on the board.
