Well apparently they're all in the hangars. I purchased these vehicles as Trevor and the Rhino, Crusader, and Barracks are all in the Sandy Shores Hangar. Press right on the D-pad to bring up list of aircraft and vehicles. Helicopters are over at the helipad near Sandy Shores Hanger (if you're playing as Trevor). For Michael and Franklin, the should show up in your personal hangars in Los Santos International Airport and the Vespucci Helipads. You must have the purchased. Each hangar in Los Santos International Airport is $1,378,000. Each helipad at Vespucci Helipads is $419,850. They can only be purchased by Michael and Franklin. I hope this helped!
