NFS Rivals

[SpiritForge7]

Hello all. 

                 I recently started playing NFS Rivals online and bought the ultimate cop pack to go with it. I was wondering if the cars in the pack are supposed to be available with the purchase, or if you still have to work your way through the levels to activate them.

Seems like they would be available immediately for use if you have to buy them but, I cannot use them.

Platform XBOX ONE.
