Hi Keeley! Welcome back!
I was just wondering. Is it a personal cars.wad or a CSM version?
If a personal one, I would suggest you to extract the wad with wadupdater and look inside if you have 11 differents teams. Because, if not, missing teams will be replaced by existing ones from your wad.
But I don't know what you want to do, exactly: specific season or something else...
