taking unique auto photography is tough...first wash your car, dirty cars just don't make good pictures (unless they are jeeps) second make sure there is nothing that interupts your car's refelection (like the other car reflected in your door) fourth, as long as the paint is in good condition shoot with the light on the car to show the depth of the paint and enhance reflection. Real auto enthustiasts will spot swirls instantly and move on but will study paint with excellent depth/reflection...i think that is enough to mess around with
