http://www.boston.com/news/nation/articles/2011/12/01/gm_chrysler_nissan_sales_up_in_november/ DETROIT—Chrysler, General Motors and Nissan reported big U.S. sales gains last month, a sign that people are finally starting to replace cars and trucks that they've held onto during the economic slump. Chrysler's sales rose 45 percent from a year earlier, while GM's climbed 7 percent and Nissan's 19 percent. The three companies were among the first to report U.S. sales of new cars and trucks on Thursday. The results underscore projections that Americans bought new cars at the fastest pace in more than two years as they replace aging cars. Analysts expect that the annual sales rate for November could range between 13.3 million and 14 million cars and trucks. That is far better than the rate of 12.6 million through the first 10 months of the year. November sales also could approach the 14.1 million annual rate from August of 2009, when the government offered big rebates for drivers to trade in their gas-guzzling clunkers. Dealers say they've had strong floor traffic all month, with surprisingly high sales for a month that's normally lackluster because of colder weather and holiday distractions. But in November, buyers went to showrooms because of good deals on leases, more confidence in the economy and a need to trade in older cars, said Ryan LaFontaine, a partner in a six-dealer chain run by his family in Southeast Michigan.
