Incentives were up nearly 10% in June from last year to boost the summer buying season, according to Dataium. Strong incentives have helped lift Hyundai and Kia over Toyota on Dataium’s monthly Automotive Shopper Intensity index, breaking the Camry’s winning ASI streak. Dataium also noted that July could be the start of a turnaround for luxury makes, as its index showed BMW and Lexus ranking first and second in ASI for all makes.
