Ally Financial has confirmed the selection Grey Group units Grey and G2 to handle its creative business, currently split among a dozen or so shops.
The assignment includes traditional advertising as well as digital, direct and retail marketing.
The bank holding company is expected to increase its total media spending to $200 million this year.
The shift came after a review in which there were three other contenders: Leo Burnett in Chicago, Venables Bell & Partners in San Francisco and the primary incumbent, Bartle Bogle Hegarty in New York.
Grey and G2 will handle the business out of their New York offices.
