Why are there no car packs in my garage?

I purchased the Forza Horizon 2 Ultimate - Anniversary Edition download for Xbox one. I do not see any car packs in my garage.

How do I access my purchased cars?


Solution 1:

I had to make sure to go to each car pack in the Xbox Store (go to the main Forza Horizon 2 store page then 'Add-Ons' -> 'See all add-ons' and click Install for each car pack.
