Unclean cars can embarrass their owners when it comes time to pick up carpool members, especially if the rear wheels are trailing toilet paper. Thwart awkward auto moments with today's Groupon at Boxley's Services, redeemable at locations in Saratoga Springs, Burnt Hills, Latham, and Delmar. Choose between the following options:

• For $20, you get two deluxe car washes (a $40 value).
• For $50, you get an exterior-focus detailing (a $125 value). Truck and SUV owners must pay an additional $25.

Boxley Services' friendly auto-body beautifiers have preened and primped Capital Region roadcrafts for more than 50 years. The deluxe wash begins with a thorough hand wash, followed by a tire dressing, sparkling of windows, and interior vacuuming to clear cockpits of crumbs, gum wrappers, and orphaned jelly beans. Alternately, the exterior-focus detailing package eliminates car skin contaminants with a meticulous scrubdown including removal of brake-dust build-up on wheels and polishing of rims. Before reuniting drivers with their four-wheeled friends, detailers swathe auto façades with a thick coat of wax to stave off wayward weather and incontinent pigeons.
