It is important to routinely groom your car—otherwise, it will grow an unsightly beard that will tickle your cheeks when you kiss it good night. Shave off soot and give your ride a much-needed lathering with today's Groupon: for $19 you get four The Works car washes (a $40 value) at USA 2 Go Car Wash in Howell.

USA 2 Go Car Wash pampers bedraggled autos with an automated car-cleansing assembly line. Give exhausted roadsters a chance to relax under soothing jets of warm water as their exteriors are treated with a tricolor conditioner, body bath, and spot-free rinse. Underappreciated auto shells get tickled with an underbody wash, and worn-out wheels get prepped for the runway with a tire shine and wheel cleaner. The automated cleansing frees exteriors of caked-on bugs, road buildup, and lodged mailboxes before doling out a high-velocity dry.

Four The Works washes can keep cars sparkling for a whole season, or they can be used all at once to blast vehicles into an immaculate sixth dimension. Bathing autos in Lustra car-care products, USA 2 Go releases vehicular companions with a clean sheen in about 10 minutes, freeing customers to mosey on their auto-powered way in record time.
