I've never had a house with a garage, but one of my friends has one. When I visited her house, I saw some oil stains on her garage floor. How many times have you seen oil stains on garage floors? Probably more than once. Do you know that if you've just made a garage and the garage floor is made of concrete, it is better to coat it with epoxy so that it'll be easier to clean?
