Is it against the law in the United States for a car rental place to allow a person under 25 years of age to rent a Full Size SUV?

Is it against the law in the United States of America for a car rental place (such as Hertz, Enterprise, or Budget Car Rental) to allow a person under 25 years of age to rent a Full Size SUV?
I'm renting a brand new three-row Full Size Ford Expedition in Los Angeles, California.
I'm 22 years old.
I have a credit card & have tried to make reservations online in advance, but worried I'm going to get denied at the Enterprise rental car desk once they see my I.D. Or somethingā€¦

Vehicle value question?

I have a question I haven't been able to find an answer to anywhere. I've found several websites stating that cars with previous rental history lowers value fairly significantly. Well, what about if the vehicle is the dealerships owners personal vehicle that was never registered and driven with a dealer plate for a year. Essentially I would be purchasing a "new" truck with 68k miles. Carfax shows all maintenance performed every few thousand and is up to date. But I've never experienced this odd situation. Is value still the same? Its a 2017 ford expedition el limited.

Can I put OEM dvd player in my car?

I recently bought a 2012 ford expedition el limited and when deciding I went with this because they came down in price to move it quick. It has all the bells and whistles except the head rest DVD players. But it does have the touch screen system in the front though. I found a totaled 2012 expedition at a junk yard that has these 2 head rest screens for 100$, can I just remove the head rests, or the seats themselves, and put them in? Or is it not plug and play?
