Monthly auto sales are up, but not a lot and not for all automakers.

USA Today reported that the month disappointed some industry watchers and automakers. That’s because February has the President’s Day holiday that automakers and dealers say marks the beginning of the spring selling season.

Slow February, slow year, is the fear.

Among the domestic makers, General Motors and FCA — formerly Chrysler Group — reported increases, while Ford Motor dropped slightly as it awaits full production of its F-150 to resume.

The increases rode the backs of SUVs and other truck models. At GM, for example, the Buick Encore mini-utility was up about 60% while every other Buick tanked. Overall, GM truck sales rocketed 36% ahead of last year.

At FCA, Jeep SUV brand continued to be the headliner — up 21.1% for its best month ever.

Still, based on its forecasts and early reports, TrueCar.com says the month is evidence that the “renaissance in the U.S. auto sector continues into February.”
