To start the workday, Aimee Byrley walks around the office and says hello to each of her co-workers. Byrley, a self-titled extrovert, said she functions better when she’s surrounded by her team at Hendrick Automotive Group’s consolidated accounting office in Cary, N.C., which covers eastern parts of the state and Virginia. The Cary office processes nearly 3,000 new- and used-vehicle sales monthly.
