Why can I not buy a car what is in a DLC pack with credits on Forza Horizon 5

Forza Horizon - December DLC car pack details

www.vg247.com/.../forza-horizon-dlc-december-car-pack-dated-detailed

The screenshot showing "included in this bundle" will only show a few as there are too many separate DLC items in it to list fully as there are 11 separate things in it:

"The Forza Horizon 5 Premium Add-ons Bundle includes the Forza Horizon 5: Hot Wheels expansion, Car Pass, VIP Membership, the Welcome Pack, and the second game expansion once it becomes available.
The Forza Horizon 4 Ultimate Add-ons Bundle includes the Car Pass, VIP Membership, Formula Drift Car Pack, Best of Bond Car Pack, and the Fortune Island and LEGO® Speed Champions game expansions"

But, as noted above, the DLC does not come as part of Game Pass Ultimate...you can buy the Bundle and play without owning the game (ie using the Game Pass version of the game)

They do show in the Autoshow.

DLC Cars

Installing DLC with cars makes each car model in the pack "Free" in the Autoshow and Buy Car menu, a one-time allowance to claim each DLC car for your garage without using credits.

From the FAQ on the Forza site.

if you're trying to buy a car that you have to pay separately for, you can't get it using the in-game economy

Also purchased Forza Horizon 2 Fast & Furious Car Pack which stated "Once the pack is purchased, you are granted a one-time only, free addition of each car to your Forza Horizon 2 garage, with no additional in-game credit cost." However, when checking the
garage in the game, the cars are not present. But, I can access the cars and "purchase" the cars still with enough in game credits. They were supposed to be a free in game addition.

Did anyone answer this issue?
