Classic American construction, or even better, modular construction.
It doesn’t have to be American built, but a big engine bay with plenty of room around the engine is priority. All modern cars have engines jammed into really tiny engine compartments, and that makes it very difficult and tedious to work on them. Maintenance time goes up, and it becomes more expensive to repair with a smaller engine bay. Naturally, this would either increase the car size (ideal) or decrease engine size (not ideal).
Also, improved safety technology. Currently, safety technology adds a lot of weight to cars. If they can trim that weight down a lot, it would be good for most vehicles to weigh under 3000 lbs. Bigger, heavier cars are safer to the people inside, but deadlier to anyone else that might be involved in a crash with those cars. More weight means more kinetic energy that has to go somewhere, so if weight can be reduced it not only helps with vehicle safety, but fuel economy as well.
