My local Target had Forza Horizon 4 Ultimate for $29.98 in the clearance section. It's insane considering the base game is the same price on sale at the same store. I'd assume it's very YMMV but there's no harm in looking.
Forza Horizon 4 Ultimate Includes:
-Early Access (doesnt matter at this point)
-Car Pass (an extra 42 cars if I am correct)
-VIP Membership (VIPs receive 3 Exclusive Forza Edition cars, VIP Crown Flair, VIP Vanity Items, VIP Emote and Car Horn, Free Player House, 2x Credit race rewards, weekly bonus Super Wheelspins, and more)
-Best of Bond Car Pack (10 cars from James Bond Movies)
-2 Expansions for Forza Horizon 4 (Fortune Island and Lego)
