Anyone have photos or suggestions for custom garage floors?

We're getting ready to remodel our detached garage and are trying to figure out what to use for flooring. My husband is starting to collect some old muscle cars as investments and wants a cool looking floor to put them on. (guy thing I guess! )
We've considered Race Deck flooring and acid etched cement. My husband would like to go with 2x2 black and white checker so some sort of tile would seem like the best option but, we're concerned with the maintenance and durability when you have old cars sitting on it. We like the look of Race Deck but are just not sure it will hold up well and I think the maintenance would be a nightmare!
Acid etching is cool and they can do alot of great design with it but The expense might not be justifiable. It's a 2000 sqft detached so need some cost efficient ideas. Does anyone have any ideas or photos I could look at or have experience with a floor that you might have?
