Although complete transparency is often viewed as an admirable quality, it can be detrimental to job interviewees, lonely ghosts, and Cinderella’s bunion-covered feet. Give your car an opaque cover with today’s Groupon: for $79, you get side and rear window tinting for a sedan or coupe at Xtreme Vehicle Designs in Noblesville (a $170 value).

Xtreme Vehicle Designs’ fenestration pros draw on 15 years of auto experience to rev up cars’ sartorial appearance and shelter their precious cargo from UV exposure with durable, professionally applied window tinting. Coupes and sedans can kiss sunbeam-stalkers goodbye as a dedicated tinting technician anoints rear and side portals with sheaves of standard LLumar film. Once applied, the proprietary UVShield technology works with a patented scratch-resistant coating to permit entry to a modest 20%–40% of ambient light while bouncing 99.9% of harmful ultraviolet rays away from upholstery, passengers’ dermises, and mobile ice sculptures.

Once Xtreme Vehicle Designs’ crew works its dark magic, horseless riders take a brisk crash course in tinted-window husbandry, which is capped off with a lifetime warranty against film peeling and bubbling. Keepers of large or sun-roofed automobiles can opt to purchase additional upgrades (not included) before zooming off to impress even the most jaded of DMV employees.
