General Motors Co, the largest US automaker, posted a third-quarter profit that beat estimates as demand for redesigned pickups and other models in North America made up for losses in Europe and in Asia outside of China. Profit excluding one-time items was 96 cents a share, Detroit-based GM said, exceeding the 94-cent average of 13 analysts' estimates compiled by Bloomberg. Revenue rose to $39 billion from $37.6 billion a year ago, missing the $39.4 billion average estimate of five analysts.
