The vehicles won't be owned by guilds from what they have said in interviews. They will be in the battlegrounds and sounds like they will just be spawned, possibly with a limited amount per area, as needed. That might just change, however when I think of the amount of effort it would take to design a system where you actually owned a vehicle it would be much easier to spawn it based on character abilities.

Another thing to think of is making "Guild owned" vehicles hard to come by people will not take them into fights. Take the game Eve-Online for example. The ships you fly in that game can be extremely expensive to buy and replace so people are usually afraid to go into battle with them. In the first year of the game fights didn't usually last much longer than the time it took the other to realise they're losing and run. There were exceptions of course but the same concept stands.

If you make vehicles somewhat difficult to obtain people won't risk them and you take away gameplay by making people hold back.
