Car troubles and speed bumps both come out of nowhere and slow you down, but only one can be fixed with a hijacked steamroller. Take a more well-rounded approach to car care with today's Groupon: for $16, you get an oil change at West Town Monona Tire (a $31.95 value).

West Town Monona Tire's staff—including four ASE-certified master technicians—coaxes smooth moves from foreign and domestic vehicles with oil changes and expert inspections. During the oil change, techs confiscate the car’s damaged oils and stolen speed-limit signs before replacing them with up to 5 quarts of brand-name conventional oil (synthetic options available for an additional fee). Once a clean filter has replaced its predecessor, techs top off transmission, differential, and windshield-washer fluid and adjust tires to optimize chassis-carrying pressure. A 27-point inspection takes techs on a tour of the vehicle, with eagle eyes honing in on antifreeze levels, examining the serpentine belts, testing the exterior lights, and inspecting the wiper blades to make sure they're sharp enough to fling away rain and soft enough not to chafe the windshield.
