Limited Edition Forza Games

Hello I own two rare Forza games I am curious about other rare Forza games so please reply with a picture of a game that you guys own I have Forza Motorsport 5 Day One edition and Forza Motorsport 6 Ten Year Anniversary Edition

I also have the FM6 10 year anniversary edition,
the only other special edition I have is the FM4 Unlimited Collector’s Edition, not sure how rare it is though, you can find all of the Forza Games, including the FM5 Day One Edition, on Amazon. They don’t seem to be limited editions, just a little bit more special than the standard edition.
