The top six automakers sold more cars and trucks in November than analysts expected, with a healthy economy, generous discounts and low fuel prices luring consumers into U.S. showrooms. Reuter's reported that the industry's annualized sales rate in November was about 17.2 million vehicles, according to industry consultant Autodata Corp. That is the best pace for that month since 2003 and well ahead of the estimated 16.7 million in a Thomson Reuters survey of 41 industry economists and analysts.
