I've searched to see if anyone has asked/answered this before but couldn't find anything about it. As we know each character in single player has the ability to store about 6 vehicles by using their dedicated 4-car garage and the garage attached to their safe house.
Is it possible to use the hangars at the airport (LS) for storing cars? That would be ideal and if it is not possible it would be fairly simple for R* to implement I would have thought. Nothing has ever come close to the "Car showroom" garage in San Andreas and the 4-car garages in LS requiring a load screen before you enter is a pita as you can't "cram" more in. I'm surprised by the promise of there will be useful things to spend your money on, yet R* give you a meager 6 parking spaces so you can't even have a decent collection of cars/bikes.
I also noticed when I was retrieving a car from the impound (with the LSPD cars parked outside) that when I drove up to the right-hand side doors (separated from the 2 doors on the left by a pillar) they opened... Did I miss an explanation hint the first time I went there or something as I don't remember which character or car I was using at the time but was surprised that it opened up. Is this an additional way of storing vehicles?
