You do not need to buy the 599GTO, you only need to buy Ferrari Enzo which can be purchased with R$ and you will manage to unlock Zenith series. To unlock RTLM you need to win 35 trophies in Zenith series and that can be made only with Bugatti Veyron 16.4. You need to fully upgrade it with R$ (PR78,9) and two Gold Upgrades (S3 and T3) to reach PR80 which cost 88GC.

Regarding RTLM I can not help you because I have just finished Zenith series and I am about to start "No compromise" challenge.

Good luck!
