This could be useful, if you want all vehicles on your server never to respawn:

pawn Код:

new carro[MAX_VEHICLES];

carro[0] = CreateVehicle(modelid, Float:x, Float:y, Float:z, Float:angle, color1, color2, respawn_delay);
carro[1] = CreateVehicle(modelid, Float:x, Float:y, Float:z, Float:angle, color1, color2, respawn_delay);
carro[2] = CreateVehicle(modelid, Float:x, Float:y, Float:z, Float:angle, color1, color2, respawn_delay);
carro[3] ...

//if you want vehicle never to respawn, use -1 in respawn_delay
//and use this callback

public OnVehicleSpawn(vehicleid) {

  for(new veh; veh < MAX_VEHICLES; veh++) {
    if(vehicleid == carro[veh]) {
      DestroyVehicle(carro[veh]);
      break;
    }
  }
  return 1;
}

I think SetVehicleToRespawn wont work after this, so you need to recreate the vehicle...
whatever, have fun.
