The car was invented to get commuters directly from point A to point B, which made life easier but destroyed the once-thriving tourism industry of Point C. Visit all points on the map with today's Groupon: for $140, you get a tinting treatment for five car windows at The Tint Shop in Murrieta (a $280 value). This Groupon is valid for untinted sedans and coupes; extra fees apply for SUVs, oversized vehicles, and cars with preexisting tints.

Technicians at The Tint Shop coat car windows in Llumar Window Films, which block out 99% of the sun's UV rays. The two-hour treatment covers portals with an upgraded tinted film and can help to preserve upholstery, reduce glare, and enhance autos' aura of mystery by giving them a Secret Service code name. Backed by a lifetime warranty, films should last without cracking, bubbling, or fading. Removing old window tint requires an additional fee, as it forces stubborn cars to temporarily reveal what's driving them inside.
