This is just not true, at least for Forza Horizon 4. Wheelspins were basically worthless and no wheelspin cars were worth over a couple hundred thousand CR. The true investments came from cars with limited availability on festival playlists.

I’m not sure what you’re referring to. What wheelspin car was worth more than a couple hundred thousand CR? I played the last game extensively and was heavy into the auction house system. The cars worth getting are those who are in the festival or Forzathon shop for a limited time
