When I was car shopping last spring ( after totaling my 2013 mazda 3 😩) I saw that the most favorable financing seemed to be available for the larger and more expensive models. Like the Mazda 3 and CX 30 had no special incentives but the CX 5 and 90 had some zero 0 interest offers. I imagine that the financing incentives are similar at different credit levels, so there could be perverse incentive to spend more on a larger vehicle because it’s the only way to get a monthly payment that fits someone’s budget.
