If gas wasn't so cheap, more likely the price of trucks would come down to compensate and the same number of units would roll off the lot. GM makes nearly $20,000 in profit on the sale of a truck. For comparison, a Chevy Trax barely sells for $20,000 out the door. The margins on trucks are huge.

It's a tough situation for buyers. I'd rather have a car 90% of the time, for a lot of reasons, but I legitimately need a truck 10% of the time. A car cannot become a poor truck, but a truck can become a poor car, and so the truck wins.
