Toyota keeps '07 Corolla prices down.

DETROIT - Toyota Motor Corp. said Friday that it is keeping U.S. Corolla prices almost flat for the 2007 model year despite rising material and energy costs. Analysts say Japan's No. 1 automaker may be fearful of yielding market share to low-cost Asian rivals. The $100 sticker-price increases, well below the rate of inflation, come as Toyota's share of the American market continues to grow, mainly at the expense of U.S. makers General Motors Corp., Ford Motor Co. and the Chrysler Group of DaimlerChrysler AG.
