DETROIT – General Motors Co. reported total sales of 207,145 vehicles in September, a 20-percent increase compared with September 2010. The automaker said deliveries to fleet customers increased 22 percent.

Retail deliveries were up 19 percent compared with the same month a year ago and accounted for 74 percent of GM sales.

“For GM, all of the factors that say this is a good time to buy a new vehicle outweigh the bad news that appears to be slowing down the broader economic recovery,” said Don Johnson, vice president, U.S. Sales Operations. “We’re well positioned going forward because we have momentum and another wave of fuel-efficient passenger cars launching over the next several months at Chevrolet, Buick and Cadillac.”
