How to use napa chassis pack in game

Playing forza 2 for like 10 mins I stopped and purchased the Napa chassis car pack , it says it’s downloaded and installed but in the game I don’t see the cars in my garage ?! I’ve uninstalled the game and reinstalled it to no luck - I’ve been trying to do this for a week

If you’ve only played for 10 minutes then that’s why. You need to progress a little into the game to unlock garage and auto show access.

You must first complete the "tutorial’ portion of the game. This extends all the way through the first award show at the main Festival Hub.

Once you’ve gotten this far and unlocked the autoshow, you must still visit it and purchase the cars - your first purchase will be for 0 CR and each one after will cost whatever the car is worth.
