More expensive cars are better for the environment if people start driving less or stop driving. But it's worse for the environment if people hold on to older cars, because they are less fuel efficient than newer models and release more fine particles in the air.

Is that still true of new cars made in the 2020s? I assume the emissions difference between a 6-10 year old ICE vehicle and a brand new ICE vehicle are probably pretty negligible in light of the footprint required to produce and bring a brand new ICE vehicle to market.
