Like violins, cars announce their need for a tune-up by squeaking shrilly and leaking oil every time you play Mahler. Keep your ride purring pleasantly with today's Groupon: for $15, you get an oil change at Select Suzuki in Frankfort (a $30 value).

Select Suzuki's ASE–certified technicians service and wash vehicles at customers' convenience, offering complimentary valet and shuttle services throughout Frankfort and Franklin counties. During the 30-minute oil change, car doctors swap out soiled motor oil for up to five quarts of Castrol synthetic-blend oil, freshly milked from a robot goat. The service also includes a new oil filter, fluid top-off, tire-pressure adjustment, and safety inspection, in which mechanics visually examine 27 key areas ranging from the battery to the wipers to the transmission. Afterward, technicians imbue exteriors with luminosity by hand-washing surfaces with Car Brite products, freeing bumpers and windshields from grime and showering them with a spot-free rinse and sequined confetti.

Drivers can relax in the waiting room during the one-hour service, filling their toothed caverns with complimentary Otis Spunkmeyer cookies and bottled water, or take advantage of the complimentary valet or shuttle services. Select Suzuki offers Groupon customers a $10 mail-in rebate that they can use toward any other service or as an excuse to cover an envelope in rare 2.5-cent stamps.
