According to Newton's fourth law, the more you drive your car, the more debris it attracts—repelling aerodynamics, the opposite gender, and gravity itself. Smooth your horseless carriage's exterior with today's Groupon: for $7, you get a full-service car wash at Soft Touch Auto Wash in Chicopee (up to a $13 value). Soft Touch Auto Wash is open seven days a week from 8 a.m. to 5 p.m., although operations shut down in the event of rain.

Hatchback stylists at Soft Touch Auto Wash vivify rides during hands-on cleaning sessions. External smudges suffer swift dismissal during an exterior wash that buffs wagon frames clean, while tarnished tires experience lustrous renewal during a whitewall treatment. Inside the vehicle, automotive clinicians provide closure for long-ago lunches by guzzling up crumbs with a vacuum. A dust-eradicating scrubdown gussies up dashboards and interior surfaces. After technicians purge windows of fingerprint mosaics and peanut-butter self portraits, roadsters bask in a final towel dry by hand, clearing them to waltz back onto paved catwalks.
