Like an Alfred Hitchcock movie, an unkempt automobile can elicit terror in all who see it and is an attractive vehicle for vindictive avian wildlife. Fend off fear and bitter birds with today's Groupon to Norm's Hand Car Wash & Custom Detail in Wilmette. Choose from the following options:

The tidy technicians at Norm's revamp sullied automobiles using alkaline-free shampoos and lubricating oils and conditioners to lock in vehicular luster. During each full-service car wash, digits don gentle microfiber chenille hand-washing mitts to bathe and dry auto exteriors, using rubber-tipped sprayers and air guns to target every nook, cranny, and cruddy Dukakis-Bentsen bumper sticker. Glass gleams after attendants cleanse windows inside and out, and vacuums scour interiors, suctioning upholstery, floors, and mats to slurp up dirt and debris. Trunks may also be vacuumed, and tires may be dressed in the latest wheel-based fashions upon request.

A complete auto detail includes all the perks of a full-service wash but takes the pampering a step further, shampooing and styling an updo for interior upholstery, swiping down vinyl and leather, buffing and waxing the exterior, and cleaning between air vents. While the cleaning crew coddle cars, guest can lounge on the outdoor terrace or in the spacious waiting room, replete with a large, flat-screen television, a customer computer, and free WiFi––perfect for emailing an ETA to a waiting garage. Norm’s also offers a free rewash in the event that customers are not fully satisfied with their initial buggy bath.
