“This year-over-year decline is not a surprise. The drop of approximately 400,000 units is largely attributed to the production cuts that the domestics announced at the beginning of the year,” Jesse Toprak, Edmunds’ executive director of industry analysis. “We didn’t expect an increase in sales for the year since the cost of gasoline and other economic trends made many people hesitate before buying a new car in 2006.”
