For how long are vehicles "safe" at outposts?

I left my buggy at the Anvil (parked in the garage area, marked as "enclosed" when I left it). Can I keep it parked there indefinitely, or will it eventually get towed and/or wiped by a coriolis storm or server restart even though it's in a sheltered area safe from regular sandstorms?

I'm off doing other things atm in game on the far side of the map, and have some IRL stuff that might prevent me from going back to retrieve the buggy for several days.
