The 2016 Nissan Frontier might be the oldest midsize pickup in the U.S. these days, but that’s not stopping customers from buying them. Nissan announced the Frontier posted a 72.7 percent year-over-year increase in July sales. That’s impressive. July 2016 sales are listed at 7,244 units. That’s far more that July 2015’s number of 4,194. It’s a difference of 3,050 trucks.
