Pistons and shafts overheat and seize up unless protected by a slick, shiny coating of oil, just like classical Greco-Roman wrestlers. Keep your engine parts from throttling each other with today's Groupon: for $19, you get a standard oil change, tire rotation, and an inspection at Muskegon Brake & Tire (a $49.95 value).

Ratcheting precise automotive adjustments since 1945, Muskegon Brake & Tire is a AAA-approved full-service auto repair and preventive maintenance center. Like administering an aloe-and-petroleum spa body wrap to a car's innards, an ASE-certified technician will drain old cruddy oil, install a new filter, and refill five quarts of fresh engine lubricant. Once each combustion system reaches smooth-operator status, Muskegon Brake & Tire turns its attention to the cylindrical air socks cushioning the ride. A technician will rotate tires and inspect the rubbery topography for troublesome imperfections and tiny secret messages. The entire oil update and tire cycle will take up to 60 minutes.
