I can't remember exactly what my AMG PR was to beat McLaren boss but I think it was around 812-820. Maxed (885PR) the AMG will take you well into Ch 19. I used it until 5 races from the end and now I'm working on the Mc650 to finish off the underground.
Just revisiting this topic, I've realized that 90 gold loading docks pick is the best value for gold. do it everyday with 50 gold per day purchase and it keeps me coming back to the game. Buying the viper srt at the start though is a good idea for farming currency and after that 90 gold per day. don't spend gold on anything else.just my thoughts..
