Immobilizer is standard on all models.
The alarm I believe it is still included on some models. Maybe only the GT? Aftermarket remote start guides reference wiring into the factory alarm to disable it during the remote start sequence. There is just no clear answer as to if the car has it or not. You can tell by rolling a window down, locking the car, then after 30 seconds manually open the door. The alarm only monitors the door triggers, there is no shock sensor, or proximity sensors.
