Like children, cars require responsible care, benefit from regular cleaning, and rarely respond to direct verbal instructions. Keep your baby up to code with today's Groupon: for $15, you get $50 worth of car-care services at Doc Auto on Ocean Street.

Doc Auto owner "Doc" Ken Potts combines his knowledge of technology with his passion for cars at his AAA- and Diamond-certified facility, which is staffed by ASE-certified technicians who service makes and models from compact car to light truck. Doc Auto's 3,000-mile service ensures functionality for further excursions ($49.95), and a tire rotation meticulously adjusts tire position for even tire wear ($19.95). To ensure minimum emissions, Doc Auto's motor menders will perform smog testing and certification (starting at $49.95 for cars made after 1995, plus $8.25 for certificate), or they can flush brake fluids ($89.95) so drivers can maintain control of their automobile friend without having to send it to obedience school. A complimentary brake inspection and motor mint are included in all of Doc Auto's services.
