I've played all the GTA's and I've had GTA5 since the release and I finished the campaign but could never get into the multiplayer aspect of the game so I deleted it after a month or so when the game was released but I've decided to give it another go.
What are some things I could do / work towards in getting?
Are there any easy money techniques or exploits?
What cars are the best?
These are some examples but I would be really appreciative if someone could give me a breifing haha.
