The Ft. Lauderdale based auto dealership chain, which is the largest in the U.S., said the new centers will give them growth opportunities now that U.S. new-car sales have flattened and prices are starting to fall.

The company says it has identified 25 sites in its existing markets to set up the free-standing used car stores. The sites will compete directly with the CarMax used car chain. Five will open next year.
