Like babies, cars are cursed with the inability to tell their owners when they are soiled, often resulting in peeling paint, rusty rims, and embarrassing rashes. Seek the intervention of a car-whisperer with today's Groupon: for $21, you get three RainX Supreme Washes at Copper Cove Quick Wash in Marietta (a $42 value).

Copper Cove, which is open seven days a week, offers speedy care and a variety of speedy car-cleaning services in its cozy, sand-toned facility. Cleanse caked mud flaps and absolve your car of stop-sign-rolling sins with a RainX Supreme Wash, Copper Cove's top express-wash package. UV protectant shields your car's delicate skin from the sun, an under-body flush freshens up its grubby belly, and triple conditioner yields a shining, silky coat of hair. The car-beautifying service also includes a three-step wheel cleanse, tire shine, clear-coat protectant, and rust inhibitor. As your auto undergoes the finishing touches of a spot-free rinse and turbo dry, soak in the sounds of Motown and suck up dust and dirt with self-serve vacuums free of charge.
