A shiny car is great for blinding potential carjackers long enough to lecture them on how you keep your vehicle so clean. Captivate your auto's audience with today's Groupon: for $19, you get a summer pass for three Super Kiss car washes (a $35.97 value) at Delta Sonic Car Wash.

Delta Sonic's Super Kiss car wash pampers four-wheel rides with a gentle, touch-free system specially developed to leave exteriors bathed and unscathed. During the treatment, autos are rinsed with water from all possible angles; a detailed undercarriage cleanse showers even the areas unreachable by crossbreeds of Mr. Clean and Stretch Armstrong. Once fully scrubbed, steeds submit to a clear-coat protectant that shields them from errant weather and guerilla shopping-cart attacks, as well as a rust inhibitor that allows them to survive the swim tests of time. In addition to an expert clean, Delta Sonic offers a free wash within five days of the original should a car "accidentally" find itself re-covered in "circumstantial evidence."
