pawn Code:

new bool:KillVeh[MAX_VEHICLES] = false;

KillVehicle(vehicleid)
{
  KillVeh[vehicleid] = true;
  SetVehicleToRespawn(vehicleid);
}

OnVehicleSpawn(vehicleid)
{
  if(KillVeh[vehicleid])
  {
    KillVeh[vehicleid] = false;
    DestroyVehicle(vehicleid);
  }
}

I just wrote that straight into the forum. I use something similar to that in my mode and it works fine. No timers needed.
