A shiny car can blind potential carjackers just long enough to distract them while you steal their bikes. Swipe dirt from your car's back pocket with today's Groupon to Collegeville Car Wash. Choose between the following options:

• For $16, you get three Ultimate washes (a $33 value).
• For $35, you get an Express interior and exterior detail (a $70 value).

Collegeville Car Wash scrubs and scours blemished vehicles to a pristine shine through newly improved services. During each Ultimate wash, mucky automobiles slink through a cleansing tunnel to receive a series of brisk splashes and sudsings. After the full four-level wash is finished, once-weathered road warriors' exteriors are polished, waxed, and dried by both towels and blown air. Wheelbrite tire and rim cleaner delivers a confidence boost to circular paws, then a thorough undercarriage wash removes embarrassing grime caused by late-night drives over jelly donuts. For more begrimed buggies, the exterior and interior car detail addresses every crevice, transforming car mats into persian rugs and cup holders into fine china.
