The unrealistic portrayal of cars in TV shows leads children to believe all cars have squealing tires, thunderous engines, and the guts to talk back to David Hasselhoff. Give your car a new image with today's Groupon: for $14, you get two full-service car washes at First Avenue Car Wash (a $27.90 value).

First Avenue Car Wash treats customers' four-wheeled steeds with the care and attention they deserve. Automotive-purification engineers begin each full-service suds-a-thon with an exterior washdown, where road debris gets sluiced away, leaving a vehicular shell glinting enough to signal Martians that you're running low on milk. Next, First Avenue's cleaning crew will vacuum the car's interior, removing crumbs from seats and gunk from flighty flux capacitors. Finally, a wash technician wipes down the dashboard and cleans the windows inside and out, leaving horseless carriages feeling prettier than a porcupine in a pincushion beauty contest.
