As aggressive incentive spending continues to sustain a robust autumn, automakers are projected to report car sales growth for November. Forecasts from J.D. Power/LMC Automotive, Kelley Blue Book and Edmunds call for a seasonally adjusted, annualized selling rate ranging from 17.1 million to 17.8 million, which would represent a drop-off from the rates topping 18 million that were posted in September and October. The projections are split on how sales volume will compare with a year ago, with estimates ranging from a 1 percent decrease to a 3.5 percent increase. Automakers are due to report November results on Friday. "While 2017 may have gotten off to a sluggish start, strong sales through the back third of the year are making up for lost time," Jessica Caldwell, Edmunds' executive director of industry analysis, said in a statement.
