About 12.8 million cars, trucks and SUV's are expected to be sold by the end of this year.
That's the highest number since 2008 when 13.2 million vehicles were sold, according to industry research firm TrueCar.com.
GM was the industry leader with 18.9% market share in December, according to TrueCar.
Ford was second with 16.5% and Toyota was third with 14.1%.
The industry still has a long way to go to get back to pre-recession sales totals. Vehicle sales in 2006 hit 16.5 million.
