How to get the special vehicles in GTA 5

Oh, special vehicles in GTA 5, my favorite subject! You've gotta complete specific missions or buy them. For instance, finishing the 'Stunt Plane Time Trials' scores you a sweet Mallard Stunt Plane. And don't forget the Space Docker - just collect all 50 spaceship parts. If you're rolling in game cash, swing by the in-game websites like Warstock Cache & Carry. They've got tanks, helicopters, you name it. Just make sure your virtual wallet is packed!
