The “Detroit Three” all saw U.S. sales increases in March compared to the same time a year ago — a boost after a sluggish start to 2018.

The Detroit News reported that General Motors Co. saw March sales leap 16% compared to a year ago on strong Buick, Chevrolet and GMC sales. The Detroit automaker moved 296,341 vehicles in the U.S. last month. Fiat Chrysler Automobiles NV saw a 14% increase in overall sales to 216,063 units. Ford Motor Co., meanwhile, saw sales increase 3.4% overall, driven by an 8.7% jump in fleet sales.

Tuesday (April 3) also marked the last time General Motors Co. will report monthly sales. The Detroit automaker announced it would begin reporting its sales quarterly along with earnings.

“Thirty days is not enough time to separate real sales trends from short-term fluctuations in a very dynamic, highly competitive market,” Kurt McNeil, GM’s U.S. vice president for sales operations, said in a statement regarding the sales change. “Reporting sales quarterly better aligns with our business, and the quality of information will make it easier to see how the business is performing.”
