Loser – Mazda -16 percent
Now for a look at the brands that fell short. First up is a surprising company, Mazda. The Japanese firm’s deliveries took a 16 percent tumble last month compared to December 2012. They build some of the industry’s most engaging vehicles so this drop is a bit of a surprise, especially since their products are always really well executed. Luckily they finished 2013 with a 3 percent overall sales increase compared to 2012.
