This happens anyway, lol. Go to a car lot and you will see the majority of cars available are black, white, silver, and maybe red. Your car will have a stereo. Your car will probably have 4 seats, not 2. Dealers stock the most common configurations and, maybe this is not your experience, but my experience is that they will twist themselves into knots to avoid helping customers make custom orders for exactly what they want, even though the manufacturer has a fancy configurator page where you can do exactly that.
I've never had trouble ordering what I wanted from the options list. That usually means needing to pay more, though.
If you want custom leather seats, you can drive your car off the lot into one of many shops that offer such services, or other customizations. Me, I drove to the stereo shop to put a better stereo in (back when the factory ones were terrible).
There are many reality shows on TV featuring shops what will custom build a car to your specifications.
