The last few decades in the auto industry have certainly seen their ups and downs. The auto industry went from selling 17.3 million vehicles in 2000 to only moving 10.4 million units in the “Great Recession” of 2009. That’s fewer sales than in 1993 when the auto industry sold 13.9 million new vehicles. Slumping sales appear to be behind us, thankfully, as 2015 posted record numbers. Some 17.5 million new vehicles found homes last year.
