Big Picture
Domestic vehicle sales are slowing due partly to stronger import demand and more largely to slower consumer spending on big ticket items. January domestic sales of 11.7 mln compare to a 12.4 mln average in 2007 and 12.8 mln in 2006. Incentives provide some monthly swing amid the downward trend. High gasoline prices provide the advantage to fuel efficient imports and domestic autos but SUV sales have not shown a strong decline given the larger discounts awarded and domestic preferences. Foreign market share has grown to 23% in 2007 at the expense of U.S. manufacturers. With a 20% weight in retail sales, vehicles provide the monthly swing to consumer spending.
