Toyota Motor Corp released figures Friday showing it was still the world\'s top-selling carmaker, with the company and its subsidiaries selling 4.91 million vehicles in the first half of this year. The group\'s total sales volume edged down 1.2 per cent from a year earlier in the January-to-June period, however overseas sales rose 2.4 per cent to 3.74 million units partly due to a strong showing in the United States.
