Great timing for me as well, I'm also planning to redo mine after 19 years since we built the house. I was actually thinking along the same lines as Dan - white and gray paint split in the middle with some black/white checkered border and then another classic car border at the top. Have also been checking out various alternatives for the floor, but may wait a year or two for that. Was actually checking on the borders and paint today.
Unfortunately I don't have all those machines to put in it like Ken above
. Besides, I've only got a 24' by 26' garage.
