There's a lot of features that aren't mandatory, but exist in just about any model so they might as well be. It used to be cheaper to get a manual transmission, now there are very few available, and usually on enthusiast models. Very few cars don't have power locks and windows. New cars generally have a touchscreen entertainment system. etc.
