Flooring question

[CarterD2015]

I am in the process of building my first shop and I have no idea what to do with the cement floors. I intend to use the bulk of the space for storage of completed vehicles and use one 20 ft bay with a two post lift to work in. I would like for it to look nice for years to come.

With that said should I use one of the two part epoxy systems, or garage floor epoxy paint or just seal the floor? I am also open to any other ideas.

Tell me what you guys think. Thanks for the input.
