Summary: August 1 (Bloomberg) -- John Casesa, senior managing director at Guggenheim partners LLC, says the auto industry's recent upturn can be attributed to buyers replacing their old vehicles. He says sales are getting stronger because many potential car buyers chose to hold off during the recent financial crisis. Casesa talks with Bloomberg's Kathleen Hays and Vonnie Quinn on Bloomberg Radio's "The Hays Advantage." (Source: Bloomberg)
