I upgraded the Ferrari Enzo Ferrari to 11/31 PR51.2, R$ only, to clear Spirit Of Ferrari. If you buy the Ferrari 599 GTO I don't think you need any upgrades on it or the Ferrari 458 Spider. That was May '15, I don't think Spirit Of Ferrari has changed.

See User blog:RR3 Michael P/My car garage, upgrades and progress though RR3 from May '15.
