Car owners like their vehicles the way that parents like their pop stars—squeaky clean. Auto-tune your auto with today's Groupon: for $22, you get three full-service car washes at Fast Eddie's (up to a $44.85 value). This Groupon is valid at the locations in Barrington, Crystal Lake, and McHenry. Trucks, SUVs, and minivans cost up to $2 extra per wash, depending on their size.

Relying on a gentle touch and hawk-like eyes, Fast Eddie's transforms sullied buggies into pristine machines, earning the car wash the Northwest Herald's 2011 Best of the Fox award. A soft cloth massages the car's exterior during each full-service wash, removing dirt, grime, and fudgy coats of Magic Shell. Human hands towel-dry each droplet, making the auto shine like a freshly polished quasar. The dashboard and doorjambs savor a thorough wipe down before a giant anteater extracts crumbs and other snacks from the auto's floor. Before the 10-minute service concludes, a sudsmaster absolves windows and whitewalls of their smudges, enabling vehicular transcendence. Owners can pass the time by teaching their pooches Irish jigs in the dog-friendly waiting area.

Though Fast Eddie's features online discounts, this Groupon offers the best deal available.
