Name that company

I trace my roots back to 1979, when the Auto Shack store opened in Forrest City, Ark. I got my current name in 1987, and debuted on the New York Stock Exchange in 1991. (My shares have risen in value more than 150-fold since then.) Today, based in Memphis, Tenn., and with a market value recently near $27 billion, I’m a premier retailer and distributor of automotive replacement parts and vehicular accessories. I boast more than 6,000 stores in the U.S., Mexico and Brazil, and I employ more than 85,000 workers on four continents. Who am I?
