Why can't I find the Karin Kuruma car in the southernsanandreasuperautos.com website? Do I have to do a specific heist/setup/mission or be at a certain level? I'm level 25 in GTA Online.
You have to finish the Fleeca Job, which is the first heist you unlock. You don't have to be the heist leader to unlock it, you just have to finish the mission, either as heist leader or joining someone else's heist.
