With the mods requesting we all create our own seperate topic I though I’d drop my list here:
I’d like to see cars from previous games return that have for some reason been cut from FH5. Since that are a lot of cars, I’m just keeping it at that, because the devs themselves know which cars those are. Please give us the Lexus IS200/Toyota Altezza though
