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 $29, you get 60 days of unlimited basic full-service car washes at Cobblestone Auto Spa (a $59.98 value). This Groupon is valid at locations in Chandler, Mesa, Phoenix, Scottsdale, and Surprise.

Cobblestone Auto Spa's wash tunnels sanctify automobiles' exteriors with sparkle-inducing full-service car washes. After technicians prep exterior window glass, soiled vehicles roll up to the purifying passageway's entrance to be gobbled up by the automated system, a network of nonabrasive cloths that scrubs away surface slime, smudge, and scratch '-n-' sniff tattoos. Windows get a final wiping once the tunnel tenderly spits cars out, and Cobblestone's staff gives the entire auto a hand-towel dry to remove every last water droplet. To keep the interior equally clean, the basic wash includes a thorough vacuuming and a damp-cloth dusting for the console, dashboard, and doors. Sixty days worth of the above services mean cars can enjoy the long-term freshness they need to hit the road with confidence.
