When you get your samples, really look at the locking system of each. Our patent locking systems becomes part of the floor structure when engaged, making them very durable in the garage.
Other things to consider are the tread patterns ( looks, how easy to clean, traction, etc). There is a fine line between being too thin or too thick for the garage environment..I'll try to briefly explain - Too thin and you have major issues with the tiles staying flat under load or over time ( they cup up), drainage & air flow,et , but cheap to make. Too thick, you have door clearance issues and more importantly you have thermal issues where the floors will buckle up with temp swings. One way to tell is if they offer what is called expansion joints, an open waffle pattern insert to try and compensate for design flaws ( popular back in the 70's when our family first came out with large area outdoor sport tiles, until we figured it our a few years later)...ok I getting off track.
Basically, just look over the samples as there is more to it than being square and snapping together, there are many long time members here that both love and don't love modular floors, lots of info here
