US car sales declined during January, we think the reason is pretty obvious: high incentive in December, low sales in January. Even so, the analysts are pretty sure that vehicles sales last month showed good results, and it won’t be the same for February. Customer confidence, better deals on vehicles and low gasoline prices will raise the demand for vehicles once summer sets. The seasonally adjusted annualized sales rate stood at 17.6 million vehicles for the month as compared with 17.9 million vehicles from the last year. Here's a detailed look at the auto sales of the automakers. General Motors said that its sales dropped 3.8% to 195,909 vehicles in January. Retail sales plunged 4.9%. Chevrolet, Buick and Cadillac witnessed declining sales each. In contrast, GMC brand sales were a bit encouraging. Again, fleet sales surged 1%. Moreover, the Detroit automaker's average transaction price got boosted by $1,200 per unit to $34,500 per unit.
