Car washes were invented to stem the tide of people purposely crashing dingy vehicles into soap factories and lathering up dirty cars to drive them underneath Niagara Falls. Revel in convenient modern-coach cleaning with today's Groupon: for $60, you get 10 Executive Express Exterior car washes at Presidential Car Wash & Detail Center in North Hollywood (up to a $139.99 value).

Presidential Car Wash & Detail Center offers automobile aficionados state-of-the-art technology, certified detailing, and convenient hours to wash their road-weary wagons. The Executive Express Exterior car wash packages an exterior and undercarriage wash with a spot-free rinse and finish. Newly grime-free vehicles soak in pampering applications of Wheel Brite, clear-coat protectant, sealer and Rainbow wax, and exterior and tire dressings leave vehicles with manicured wheels, shiny coats, and wagging bumpers. Open seven days a week, with convenient winter and summer hours, Presidential Car Wash also boasts a number of environmentally friendly practices and products, including a high-tech water-recycling system and a plethora of biodegradable soaps and waxes. Should a ride get caught in a torrential rain shower or a pigeon's coffee spill within 24 hours of its bath, the buggy beautifiers will wash it again, free of charge.
