The 1977 Cadillac Sedan de Ville was Walter White's car for the final day of his life ("Felina"). It was sold to him by the arms dealer Lawson ("Live Free or Die"), primarily for the illegal M60 concealed in the trunk. It was collected from a Denny's parking lot and used to transport Walter to his old home ("Blood Money"), Skyler's Apartment and the White Supremacist Compound. It was last seen abandoned in the compound, severely damaged from machine-gun fire, presumably to be later seized by the arriving Albuquerque police.
