To check the level of your garage floor buy two metre rules, tape a length of 8mm clear plastic pipe to one rule and ensure you have enough pipe to run the distance you wish to check, tape the other end to the second metre rule. Pour water containing a food dye into the plastic pipe, and place one ruler at one end of the garage and the other at a second position.Get the wife/girlfriend to hold one ruler vertical, you hold the other one vertical, water will form a level, read off the difference between the two rulers. Cheap as chips!

That's an idea too!! cheers!
