I think so. I just made this work like 40 minutes ago. My friend and I tried it but we had no luck.Was this HOTFIXED? Because when I park my limo to block the garage and then I pick my car it still has the tracker on it. I've started new lobbies too and that doesn't fix it. I think I may be missing a step here (such as buying the rebel before and stuff....I'll try that lol)
EDIT: Managed to get it work.
