Note to read before entering. Take a moment to check do you own this already. The actual Steam license ID for this DLC is 8640. But the store page ID is 8780. Since those 2 IDs don't match SteamGifts (and Steam Store itself) don't see this as owned. Just like Back to the Shop Addon for Crazy Machines 2 for example. Except this one actually shows up in your Steam library listing as an individual entry.

-If you have entry titled "RACE On" and link to the Store is https://steamcommunity.com/app/8640 you already own this.
-Alternative way to check if you own this is with Steam console command: licenses_for_app 8640
-Nobody can own 8780 because there is nothing to own https://steamdb.info/app/8780/ just the Store page http://store.steampowered.com/app/8780/
