Unlike cats and germaphobes, automobiles need to be reminded to wash themselves. Drop a blatant hint to your lazy ride with today's Groupon: for $25, you get three Directors car washes (a $57 value) at Celebrity Car Wash and Maintenance Center, located in Flower Mound.

Celebrity Car Wash cleanses star-worthy motorcoaches with a selection of luxurious and environmentally friendly services, including the prestigious Directors wash, named after Alfred Hitchcock's notoriously rust-free chassis. Following a thorough soft-touch bath, the friendly technicians will tickle grit and grime from car windows, wheels, and exteriors, before guarding it against chafing with a microfiber towel-dry. Next, a complete interior purging, clear-coat protectant, and triple-foam polish impart a lasting luster inside and out, and a celebrity fragrance will help give credence to your insistence that Dom DeLuise has been haunting your glove compartment. While car's end their spa day with a tire shine and undercarriage treatment, owners can pamper themselves with free WiFi, Starbucks coffee, and several TV sets, or synchronize their watches to start the clock on Celebrity Car Wash's 48-hour guarantee.
