I have a feeling you are rewarded for getting them all but I doubt it. Unfortunately I can't get the LAST RANDOM EVENT TO TRIGGER It's Simeon Yetarian! The guy you help do the repo business as Franklin. On my Social Club checklist, it says that is the only Random Event left to do. I am sharing to you guys to see if you have any luck triggering it. Once you load up the save, the location is up to the left on the corner. The CAR SHOWROOM at the corner. Please help me out and tell me if you get it to trigger. I'd love to have a PERFECT GAME on GTAV. I am starting to think it's glitched but I hope not. The screenshot map shows the exact location.

It's sad, but this random event triggers only after Complications mission and before Mr. Philips mission. Learnt it just now. I think I'll have to start a new game. Ah well...
