Jaguar, which is headquartered in Irvine, Calif., and Coventry, U.K., put the account, handled by WPP Group's Y&R Advertising and Wunderman, direct marketing agency, into review in early November. The incumbents intend to defend the business.
WPP has a longtime relationship with parent Ford, but Jaguar management has said it will talk to agencies outside the WPP family.
The automaker said it anticipates that the review will be completed by the end of March 2005.
