Neglected cars try to escape their owners by parking in tow zones or running away from their garages to join the demolition derby. Keep custody of your car with today's Groupon: for $13, you get three self-serve Grande car washes at Rio Car Wash (a $27 value). Choose between the following locations: Midlothian and Richmond.

Rio Car Wash's self-serve facility treats filthy cars to a quick soft-cloth bath that's over in three to five minutes. The scratch-less wash includes rain repellent, foam polish, and a clear-coat sealant to keep colors from fading into dust-coated dreams, as well as an undercarriage wash to chip off all the grime, sludge, and CB radio slang picked up from the road. After applications of rim cleaner and tire shine ensure that wheels and their rubbers stay clean, autos get dried off and then open wide to expose their interiors to vacuums, which remove loose debris and replace it with surfaces clean enough to play Go Fish on.
