"Yet after BMW, Mercedes-Benz, Acura, and Cadillac all failed to match the rate of industry-wide expansion in 2015, the first four months of 2016 have revealed that even more top-level premium brands are fading as the market for new vehicles continues to expand. U.S. auto sales are up 3.4 percent in 2016. Mercedes-Benz, Lexus, BMW (the three top-ranked premium auto brands), Acura, Cadillac, and Infiniti posted declining sales in the first-third of 2016."
Is this a symptom of the ongoing recession, or a trend of changing taste?
