The title might be a bit misleading, but I'm currently running the Community Ultra Pack and was wondering to basically save more car slots by making certain cars unlockable via tuning. E.g. buying a Ferrari 430 Spider and then taking it to the tuner to unlock the 430 Scuderia Spider 16M for the difference of what the cars cost right now (170k for the base 430, 210k for the 430 Scuderia --> 40k for the tuning kit).
Would that be possible and, if so, how would I go about doing it?
