If you do not see those statements as complementary, that is on you, not on me.

Most people who buy cars don't actually give a shit how many cylinders, spark plug configuration, or hamsters are involved in the engine. They want to know that it will work and not cost them too much in fuel, maintenance, insurance, and repairs. They want it to "look good" for their sense of style, and they want it to be a "safe" car.

In order, it's usually price, style, then fuel efficiency (not engine, but whole car fuel efficiency), insurance cost, and everything else. For some people, it ends up being style, price, then everything else.
