The object (or vehicle in this case) name is whatever u call it when u place it.
I would head over to the editors dept and pick up a vehicle respawn tute.
This only works for SP games (i think), but try it anyway:
;To execute, enter into each vehicle init field: [NAME-OF-YOUR-VEHICLE-HERE,40] exec "Vehiclerespawn.sqs"
Copy this into a notepad and call it Vehiclerespawn.sqs then put it into your mission folder.
;----------------------------------------------------------------
?!(local server) : exit
_vehic = _this select 0
_time = _this select 1
_type = typeof _vehic
_pos = getpos _vehic
_dir = getdir _vehic
#loop
_vehic addEventHandler ["killed", {[[0,0,0],[0,0,0],60,3+random 3,_this select 0] exec "\KEGnoecain_snow\script\destroy.sqs"}]
@!(alive _vehic)
~_time
deletevehicle _vehic
_vehic = _type createvehicle [0,0]
_vehic setpos _pos
_vehic setdir _dir
_vehic setdamage 0
goto "loop"
;--------------------------------------------------------------------------
Now preview and take a LAW to your vehicle and it will explode, burn for a while and respawn wherever u placed it in 40 seconds.
