There was a McLaren P1 GTR in the Forza 6 DLC, and there’s a Zenvo ST1 and Pagani Zonda R in the Forza Horizon 3 expansion. You can’t tormet us collectors like this by having such cool cars in a Hot Wheels DLC but not as actual models :(
Granted, the licensing is probably a lot different for video games, but, you can’t tell me Hot Wheels isn’t long overdue for a Zonda.
