Vehicles set to respawn, don't respawn

[Fabio(GNR)]

So basically i have created a vehicle, i set it toggleVehicleRespawn to true and the idletime but it doesnt respawn

code:

function start ()  
veh57 = createVehicle (493 , 3707.64453125, -2059.986328125 , -0.15620525181293 , 3.0322265625 , 359.93408203125, 75.569458007813 )  
 toggleVehicleRespawn ( veh57, true ) 
 setVehicleIdleRespawnDelay (  veh57, 35000 ) 
end  
  
addEventHandler ( 'onResourceStart', getResourceRootElement(getThisResource()), start ) 

So whats wrong?

EDIT: should i use spawnvehicle instead of createVehicle?
