Like sequined life jackets and designer dictionaries, tinted car windows are both stylish and practical. Look good in the shade with today's Groupon: for $42, you get tinting for your car's front-door windows from Al's Window Tinting (an $85 value). This service is valid for areas within 20 miles of zip code 33755.

Al Nelson of Al's Window Tinting, who has worked with high-profile customers such as Whitney Houston and Dennis Rodman, dispatches his team of technicians to cover cars' two front-door windows in professional-grade film. Vehicles can lounge lazily in their own familiar driveway, parking spot, or traffic jam as the traveling technicians neatly lay tinted film across the glass. The film—which filters out 56% of incoming heat and 75% of glare—maintains cool, comfortable interior temperatures while protecting seat upholstery from sun damage and preventing drivers from being distracted by solar rays or lunar conspiracies. Originally from California, Al Nelson has plastered his expertise across an admirable collection of windows, from Disneyland's tourist trolleys to the rides of professional sluggers.
