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 $15, you get $30 worth of car detailing and hand washing at Hickman Auto Spa, located on Kenmount Road.

Hickman Auto Spa buffs soiled sedans in an expedient and personalized service. Feral drivables detangle in the Hercules 5000 ($14.95), an innovative scrub system designed so no moving parts touch the car, minimizing scratches and maximizing the longevity of dashboard Jenga installations. A Hercules basic car wash hand cleanses external auto auras, tires, and rims, and can come accented with a Hi-Glo sealant ($19.95) or paint sealant ($24.95). A 1 Diamond Express ($39.95) adds an interior cleaning, which includes a window washing, a vacuuming of seats, carpet and floor mat, and a nostril-rejoicing deodorization.

Supplementary services in the 3 Diamond Express ($229.95) include the shampooing of under-the-hood tresses, and an FLR stone chip and scratch repair ($79.95) evaporates nicks caused by wayward pebbles and displaced razor fish. Create your own van-mending mélange from Auto Spa’s service menu to personalize detailing.
