Even as its core new-vehicle markets softened, Group 1 Automotive Inc. boosted profits in the fourth quarter on strength in used vehicles, service and finance and insurance.

Fourth-quarter revenue for the Houston-based dealership group climbed 7 percent to an all-time record of $3.11 billion. Net income jumped 57 percent to $48.1 million.
