Automobile dealerships in Gainesville are seeing huge upticks in sales this year, believed to be on the upswing due to lower interest rates and higher consumer confidence. Kelley Blue Book estimated before Black Friday shopping that the seasonally adjusted annual sales rate for November was 16.8 million nationally, up 2.2 percent from November 2013. The annual sales rate reached 17.2 million, according to Autodata, after the shopping holiday, boosted by a host of stronger economic indicators.
