Options add value, in luxury cars, a sunroof and alloy wheels are pretty much essential, not getting one means negative value on resale.
The dealerships often mark up prices on cars just because... It always amazes me how many people think sticker prices are firm and fixed. I have never purchased a car in my life without getting at least $7k off the sticker price.
There are many walks of life. A self employed realtor, for example, can write off a car lease, and may need to regularly carry clients, so an expensive sedan or big SUV ends up helping them more. People are so used to projecting their own circumstances on evaluating everyone else when it comes to economics, benefits of financial decisions are always subjective.
