CarMax Inc. (NYSE: KMX) is getting squeezed by its own rising cost of borrowing money to finance consumer vehicle purchases, weakening consumer demand spreading across the board, declining customer traffic into sales locations, lower gross profit margins per vehicle, and rapidly accelerating declines in the resale prices of trucks, SUVs and other gas hogs already parked on its lots. All these factors mean that CarMax 1Q FY2009 EPS dropped to $0.13, down 55% from 1Q FY2008.

Don't look for improvement in any external factors in the near future. Nevertheless, CarMax senior management has decided to continue with its aggressive expansion program in order to gain market share across the country. Thus far, CarMax has opened six new used car superstores in 2008 with plans to open eight more. The company is also testing a program to centralize its appraisal and car buying programs into five car-buying centers spread throughout the country. CarMax hopes to obtain more of its used vehicles for resale directly from consumers rather than wholesale auto auctions. The profit margin is higher for CarMax on vehicles obtained directly from consumers.

CEO Tom Folliard has suspended guidance for the rest of FY2009 given so many broad-based economic uncertainties, including continued uncertainty in the subprime lending sector. CarMax's income from financing declined $27 million to $9.8 million in 1Q FY2009. The company is facing higher funding costs and higher loss assumptions. Presently the stock is trading right around $16, but will face an uphill battle just to stay in that price range.
