For spirit of Ferrari: We can get 599 GTO in main career for showcase discount, no need for other series. Also focussing only to proceed, we need 39 trophies to unlock next series. Therefore only 75% completion is required. Also calculating from Michael's website 599 GTO can achieve 55 PR for RS upgrades only. Therefore saving gold. I hope I'm right
