New auto sales in the domestic market fell for a third straight month in October, led by Toyota Motor Corp. and Nissan Motor Co., data from an industry group showed Tuesday, as a slowing economy kept buyers out of showrooms.

Sales of cars, trucks and buses, excluding minicars, fell 13 percent to 233,922 vehicles in October, the Tokyo-based Japan Automobile Dealers Association said in a statement.

Toyota Motor Corp., Japan's largest automaker, sold 117,642 vehicles excluding the Lexus brand, down 14 percent. Sales at Nissan Motor Co., the country's third-biggest carmaker, fell 20 percent to 31,708.
