As a kid, it was easy to say things like, "One day, I'm going to drive a racecar." For many, those thoughts came before the reality of having a mortgage, bills, and a budget set in, a realization that ended those most lavish of childhood dreams. As its name suggests, One Day Luxury strives to make those dreams come true—even if it's only for single day. The company rents out rides by the hour and by the day. Its garage gleams with exotic cars, including a Lamborghini and Audi A8, and classic muscle cars, including a 1978 Corvette. For a little less power and a little more zip, travelers can also hop on jet skis and Ducati motorcycles.
