Fields Auto Group, an automotive dealership network, agreed to acquire two car dealerships Mercedes-Benz & Sprinter of Orland Park and Mercedes-Benz of Bourbonnais from Sun Motor Cars of Chicago. Financial terms were not disclosed. “When we decided it was the right time to sell, we knew Kerrigan Advisors had the most experience with higher value dealerships. They’ve sold more luxury franchises in the Midwest, particularly Chicago, than any firm in the industry,” Dan Sunderland, Sun Motor Cars of Chicago Co-Owner.
