1) Pause as you enter the LS Customs
2) Press triangle, then immediately spam right on d pad and triangle (if done right your character should exit the vehicle and you should enter the shark card screen)
5) Wait 30 seconds on the sharkcard screen
6) Exit the sharkcard screen and get your friend to drive the car out of LS customs
7) Change the vehicle access (if you don’t you can’t enter the car even if you own it)
PS: You can change your vehicle access back to everyone if you want it as that once you enter the car.
The godmode will only be removed if you enter an interior with the car e.g garage, avenger, moc or if you return your vehicle to storage via the interaction menu
