Or order it from the factory with exactly the spec I want... but 99% of people are too impatient to wait for a vehicle to be delivered from the factory and most dealerships don't give them that option because they want what's on the lot gone.
I get it. It's easier to shift vehicles if they all conform to some common spec because then there's nothing that makes worlds different. You pick this spec or that spec, end of story.
But I've played this game too many times with dealers and I just can't be bothered any more, which is why I drive an 8 year old Volvo that is good enough. Would I like a new car? Of course, I'd love a spanking new truck, but the glory of driving off the lot with a brand new vehicle that's not quite exactly what I wanted just isn't worth the loss of the 30% of value as I leave the lot and certainly not the tediousness of talking to car sales people for a day while they fuck around upstairs trying to stress me out.
I'll bring my laptop and use your WiFi to work. I'm quite comfortable helping myself to your endless tea or water from your service department waiting room while I'm in your showroom. No, I'm not giving you the keys to my vehicle which is parked outside your lot on the street so you can't box me in, and here's a photocopy of my driver's license which is plenty adequate for your needs, the original stays in my wallet. Now fuck off and do your job and if you're not back here with the keys, ownership papers and plates to a new car matching the spec I specified by the time I'm finished this user story, you won't find me still sitting here. You wanna play games, play them with someone else.
