Cars of Atlanta's sleek showroom emphasizes the company's specialty in a spectacular way: various wheel rims fill the shelves just inside the glass front entrance so that the elaborate metal rings can be seen in silhouette by anyone inside who looks outside. Once home to a car repair shop, the space now resembles the hold of a flashy cargo plane. In addition to wheels and tires, other specialties include alignments and high-speed on-car computer balancing, alarm installation and integration of iPods and navigation systems.
