But the meagre 0.3 per cent increase masked big gains by many import brands, which overall saw January sales increase 8.5 per cent year over year. That compared with an overall 8.1 per cent decrease for the so-called Detroit brands, DesRosiers said.
"January is always a troubling month for vehicle sales and not necessarily just because of the weather," the consultancy said in a commentary.
It noted that companies can be under tremendous pressure in December to meet specific sales targets and will often go to extraordinary lengths, including the use of aggressive dealer and consumer incentives to bring sales forward.
"We often see double-digit increases in December as sales are pulled forward followed by double-digit decreases in January when reality sets in," it said.
