I think it would look better with the "Sprite-boy" sticking his creepy face out of the trunk on the '57 Chevy kinda like Freddy Kruger beckoning you to your Death ( Er..Coke) " it kinda reminds me of the old "BeerMachines.com" website (they were on Ebay too) selling Beer themed 60's coke machine? this would fit right in
