FORT LAUDERDALE, Fla. — AutoNation Inc. reported today that first-quarter net income rose 13.7 percent from a year ago. Revenue also was up 12 percent from a year ago, driven by strong performance in all of the company’s business sectors, including new and used vehicles, parts and service and F&I.

“AutoNation delivered solid double-digit growth in operating income, which drop a 21 percent increase in [earnings per share] from continuing operations in the first quarter of 2013, as we increased profitability in each of our business sectors,” Mike Jackson, the group’s chairman and CEO, stated in a press release. “We continue to expect industry new-vehicle sales to be approximately mid-15 million units in 2013.”

The dealer group also announced that it has signed agreements to acquire SanTan Honda Superstore and Hyundai of Tempe in Phoenix, and Don Davis Toyota Scion in Dallas. The annual revenue for all three stores is approximately $250 million, and together, these stores sold approximately 8,300 new and used retail units in 2012.
