So....some dude gets the camera Ive been saving up for for 2 years....and one of the 5 cars Ive always wanted. God I wish I was you.
I like number 2, try lightening it up a bit though...try a fill flash or something.
Oh, and you might want to get a polarizing filter for shots like #5, the polarizer can be set to remove most if not all the reflected light, and can also be set to do almost nothing.
