Washing a car, like performing taxidermy on a marlin, keeps it looking the way it did when it first came off the line. Preserve your greatest catch with today's Groupon: for $15, you get one month of unlimited car washes at Green Clean Car Wash in Pine Brook (a $34.97 value).

Green Clean Car Wash’s The Works package drenches motorized steeds in environmentally safe products using technologically savvy equipment. Inside a cleaning cave, buggies are cleaned grill to bumper in roughly 10 minutes, beginning with double-bond Teflon protection and three layers of foam polish richer than mousse made with liquefied yachts. Tire dressing and rim cleaner preserve the effervescence of rubber rollers, and clear-coat protectant safeguards paint from loss of color and respect from vehicular peers. A thorough underbelly scratch riddled with antirust solutions rewards mechanical companions for their faithful service, and a finishing exterior wash removes sudsy remnants and kamikaze mosquitoes.
