The growth of Lithia motors closely tracks the recovery of the American economy. The Oregon company’s stock cratered in March, 2009, as Americans cut back on spending after the financial collapse. But as auto sales have bounced back, so has Lithia’s stock. Trading below $3 in the first part of 2009, the shares are now above $65. The network of car dealerships in Western States – their eastern-most shop is in Ames, Iowa – saw a 17% increase in sales in the second quarter this year, with revenue climbing to $27.4 million, a 41% increase over the 2012 numbers. --C.G.
