Although dirty cars don't develop a disagreeable smell, the unwashed automobile is more likely to drive itself to France and storm the Bastille. Curtail vehicular revolt with today's deal: for $15, you get a Hi-Tech Works Wash (a $29.99 value) at Matt and Jeff's Car Wash, an award-winning car cleanery in Novato.

The Hi-Tech Works Wash bestows a bevy of bright, shining benefits upon cars and their owners, beginning with a complete clean and spot-free rinse. Following the dirt-busting brushing, cars get the full protection package blasted over the appropriate areas of carnatomy—a “30-day wax,” Rain-X all-surface protectant to wick moisture away from windows, a wheel trim and whitewall cleaning, wheel-trim protection, clear-coat protection to keep the paint job spiffy and crystal-clear, and a tire dressing in either Thousand Mile or ranch flavors. Groupon users also receive a gift card valid for $0.10 off each gallon of gas from Matt and Jeff’s on-site fueling station for six months, as well as the option to get a discount on detailing—call for more information.

A sparkling-clean car sends a clear message to all who observe it—although dust and dirt are fine to drive upon, humanity cannot brook them hitching a ride on such fine automobiles.
