Chrysler Corp., saying it is tired of seeing the image of Japanese carmakers boosted by misinterpreted sales figures, said it will stop reporting its vehicle sales on a 10-day basis beginning in January.

The decision to report sales numbers only at the end of the month would end a longstanding industry tradition of reporting new car and light truck sales in the United States every 10 days.U.S. vehicle sales reports every 10 days are considered one of the nation's leading economic barometers.

Chrysler said the move is a cost-cutting measure, but Chrysler executives have made it clear in recent months that they are angry with way the news media handle the reporting of 10-day numbers and allege that the reporting boosts the image of the Japanese.
