The question was "Is it included in the purchase price of the new vehicle?"
You're saying it's not?
The question was "Is the part available at any dealership?"
You can buy a Demon at any Dodge dealership and get the crate.
Both your questions were answered correctly
The answers to both are Simple No.
The crate is not included with the car at the time of purchase.
No dealership has the crate sitting next to the demon to take home with you.
