GM second-guesses big sales incentive reversal

The car maker also announces it will reduce its cut-rate fleet sales to car rental agencies by another 100,000 vehicles.

LAS VEGAS (Reuters) -- General Motors Corp plans to reduce sales to car rental agencies by an additional 100,000 units in 2008, capping a three-year effort to cut back on such cut-rate sales, the automaker's North American chief said on Friday.

Separately, GM (Charts) North America President Troy Clarke said he was concerned the No. 1 U.S. automaker had "over-corrected" by throttling back too hard on sales incentives in January in light of the month's 16 percent drop in overall sales.

"I wish we had done a little better on retail sales," he told reporters on the sidelines of an automotive conference sponsored by J.D. Power.
