Funmw2 is known to be a snooper in the files of GTA 5 and he has leaked information about what to expect in the game, in the past he has had a good track record.
He said that three cars are coming to GTA 5; these are the Massacro and Zenntorno, which are sports cars, along with the Huntley.
The Huntley has been modelled around the Hummer and past GTA games have featured it, so it’s no surprise to see it make an appearance in GTA 5. In GTA 5 the Huntley is based on the latest model of the Hummer and you can see it here.
At the moment we have no idea when to expect the heists, but Rockstar did say that they would be coming this year. They are the one thing that gamers want the most from Rockstar.
