It's not just your copy of the game, no copy of the game features the modern Challenger.

But it says it’s available but it’s not

Where does it say that it's available?

I point you to the Master Car List, which contains the following entries for Dodge:

Dodge (13)
Challenger R/T 1970
Charger SRT Hellcat
Charger SRT Hellcat Safety Car
SRT Tomahawk GTS-R Vision Gran Turismo
SRT Tomahawk S Vision Gran Turismo
SRT Tomahawk Vision Gran Turismo Gr.1
SRT Tomahawk X Vision Gran Turismo
Super Bee 1970
Viper Gr.4
Viper GTS 2002
Viper SRT-10 2006
Viper GTS 2013
Viper SRT GT3-R 2015

No modern Challenger on that list = not in the game. The 1970 model will either appear in the Used Car Dealer or the Legendary Car Dealer.
