The hum of a smoothly running engine, the whisper of newly tinted windows rolling up, and the swish of industrious windshield wipers. The ASE-certified technicians at Specialty Auto Sales & Service create this symphony of sounds as they repair and replace vehicular components ranging from troubled engines to phlegmy exhaust pipes. They can also trick out autos with custom work such as tinted windows or high-intensity discharge headlights. In addition to repairs, installations, and basic maintenance services, the center matches drivers with used cars. Its shifting inventory ranges from Fords and Pontiacs to Chevrolets and Saturns, originally developed to zoom around the planet’s racetrack of rings.
