Your car relies on you to maintain it regularly and not to gun it across any rivers, even if there are free Thickburgers on the opposite bank. Keep your vehicular promises with today's Groupon: for $24, you get a Texas state inspection and hand car wash at Don Herring Mitsubishi (a $54.75 value). Choose from the following locations: Irving, Dallas, and Plano.

For more than three decades, the experienced hands at Don Herring Mitsubishi have been repairing and rejuvenating automobiles in the area. Seasoned technicians will closely scrutinize safety items such as tires, brakes, wiper blades, and lights during the Texas state inspection, which covers all emission components to ensure your vehicle maintains proper operation and bowel movements. This deal also includes a thorough hand-washing of all participating vehicles, as Don Herring's meticulously detailed staff vacuums up dirt and plaque buildup trapped in automobiles' interior fissures.

All three locations close at 5 p.m. on Saturdays and are not open on Sundays.
