Last week's trivia answer

Founded in 1957 and based in St. Louis, I'm the largest car-rental company in America. I sport more than 7,000 offices (including more than 240 at airports) and will pick up my customers for free. I have more than 700,000 vehicles in service, up from 90,000 in 1990 and 500 in 1970. I rake in more than $10 billion annually. I'm a privately held company, though, so you can't buy stock in me. I've been named a "Customer Service Champ" several times by BusinessWeek and am one of the largest recruiters at colleges. Who am I?
