That seems disingenuous. No doubt there are some car owners who do care about these things, but the vast majority of drivers would likely be hard-pressed to know what type of engine their car has, or what the differences between rear and front drive are. Most people select cars based on some mix of cost, perceived safety, utility, and by what other people they know are getting.
