Let me break down the vehicle system for you since it works differently than you might expect. The system operates through a virtual menu where any cars you've bought or earned through missions get automatically registered, and you can call them to your location with just a button press. When you're thinking about storing vehicles, remember that trying to keep stolen ones isn't going to work - they'll despawn as soon as you walk away which is actually pretty important to know.

While you technically can park your owned vehicles near v's apartment garage or other spots around the city, don't count on them staying there permanently since they might vanish when you reload or leave the area. Something interesting to note is that the virtual system actually makes things more convenient, letting you summon different rides instantly instead of having to run back to a physical garage. If you're really set on having traditional garage features, there are mods available that'll let you expand on the base system, but the core game keeps things streamlined with the virtual menu approach.
