My last suggestion for FH6 after the launch of this game on PC and Xbox consoles is to add 2 New-to-horizon cars into the roster during the game’s future updates via Festival Playlist, Autoshow or a DLC pack that should be automatically free to download for those who buy the Ultimate Edition. The following cars are:
