Downloaded car packs not showing in my cars

Hey guys,
Havin a bit of trouble accessing my downloaded car packs. They dont seem to be accessible through my cars. Can anyone help

If a car pack has installed correctly the cars will appear in the Autoshow/Buy Cars menus for 0 credits where you can buy them for your My Cars collection. Are you saying they aren’t in the Autoshow, or that when you try to buy them from the Autoshow you’re prompted to purchase/install the DLC? Or that you bought the cars but now when you attempt to use them in your My Cars collection they’re either not available or when you select them they prompt you to purchase/install the DLC again?
