Window tinting gives cars a mysterious air and increases their chances of getting cast as the lead in a film noir. Make your car a star with today's Groupon: for $60, you get tinting for two car windows at The Best Guys in Concord (a $125 value).

At The Best Guys, a LLumar-authorized dealer, technicians precisely cut and smoothly apply scratch-resistant window films using thin, high-performance resin adhesive that prevents unsightly bubbling and cracking. The auto artisans use a computer program to trim sheets to the exact right shapes—a process that thwarts possible damage caused by using traditional scissors coated in olive oil. In addition to deflecting glare, window tinting protects car interiors from fading and aging by repelling 99% of all UV rays. Additionally, should a car ever endure an accident or drive through a cave filled with dive-bombing bats, window tinting often holds glass pieces together to protect the skin and eyes of passengers. While passengers enjoy a ride free of scorching temperatures and prying eyes, car owners rest easy in a dual lifetime warranty, courtesy of both The Best Guys and LLumar.
