A shiny car can blind potential carjackers just long enough to distract them while you steal their bikes. Maintain your ride's sparkle with today's Groupon: for $29, you get six full-service car washes at Skyview Carwash (a $69.75 value).

Skyview Carwash's experienced auto attendants upgrade vehicles' inner and outer appearances during a thorough 15-minute cleaning. The exterior rinse removes mud, insects, and used cucumber slices from cars' countenances, and the wheel wash flosses away gravel and bits of Cracker Jack from tire treads. Technicians then spelunk into vehicular interiors for a thorough dirt excavation, emptying ashtrays, washing windows, and dusting dashboards, doors, and steering columns. Suction-powered vacuums whisk away particles hunkered deep in floors and seats. After the first wash, patrons receive a voucher booklet for the remaining five washes, which can be redeemed for any motor vehicle or horse-drawn Hoveround.
