Auto sales rose 6.8% in Orange County last year, and are expected to increase 4.1% this year, according to the Orange County Automobile Dealers Association.

The Newport Beach-based association bases its numbers on new vehicle registrations in the county. Its latest Orange County Auto Outlook report said dealers here sold 176,803 new cars and light trucks in 2014, and projected a total of 184,000 for this year.

The report anticipates a “slight increase in interest rates in 2015” but expects the effects to be offset by a hike in employment and wages along with falling gas prices, “which should give a boost to disposable incomes.”
