General Motors reported U.S. car sales in January were down 6% from the same month a year ago.
But GM's head of U.S. Sales, Don Johnson, says comparing the two months is tough. That's because the Detroit automaker boosted sales significantly last January with incentives.
Johnson says the good news is GM increased its market share in the U.S. last month, compared to December. GM had about a 19% market share last month.
Johnson says it's not possible to predict gasoline prices, but for most of 2012, he thinks they'll stay under $4.00 a gallon.
In 2008, when gas prices spiked suddenly, exceeding an average of $4.00 a gallon, consumers flocked to dealerships to buy small, fuel-efficient cars.
