In Keep Calm and Carry On , Dean leads a resurrected Mary Winchester to the Impala which is in the bunker's garage. Mary recognizes the Impala as her husband's car and treats the Impala in a similar manner to how Dean treats the car. While examining the Impala, Mary stares into the backseat with a huge smile, presumably remembering fun times with John in the backseat. Later, while driving, the Impala is rammed by Ms. Watt with an SUV, leaving a dent in the rear right quarter panel. The Impala is temporarily knocked out of commission by the hit, but remains driveable and the Winchesters and Castiel drive off in it after killing Ms. Watt.
