December auto sales at Chrysler Group LLC were up 6 percent. However, the December figures were 1 percent shy of analyst expectations. Chrysler sold 161,007 new cars last month. Truck sales continue to dominate for Chrysler. For example, Jeep sales were up 34 percent compared the same month a year ago. The new line of Jeep Cherokees (mid-sized) and the Grand Cherokee led way for Chrysler. This past December was Chrysler best December in six years. Now that Fiat SpA (BIT:F) will have total control of Chrysler, Chrysler’s slated IPO in 2014 got a great boost from the December auto sales.
