Dean Winchester drives a black 1967 Chevrolet Impala. Having been passed down to him by his father, John, it is Dean's most prized possession, with actor Jensen Ackles feeling it is Dean's "life" and "sanctuary". The brothers travel in it throughout the country as they hunt the supernatural, and the trunk holds various weaponry and their fake ID's. In the first two seasons, it has a Kansas license plate with the number KAZ 2Y5, a reference to the Winchesters' home state of Kansas, and the series premiere date of 2005. Towards the end of the second season, the car sports a new Ohio license plate (CNK 80Q3) to aid the brothers in hiding from the FBI.
The origins of the Impala were first depicted in the comic mini-series Supernatural: Origins, in which John Winchester takes ownership of the car from Mary's uncle after accidentally getting him killed during a hunt. However, fans responded negatively to this, as John is shown with the Impala in the teaser for the pilot episode, which is chronologically set before the comic series. Due to this, the comic was altered for the trade paperback version, with the Impala's true origins later being depicted in the series' fourth season. Having been sent back to 1973 by the angel Castiel, Dean convinces his father to purchase the Impala over a 1964 VW Van. The car's origins were further explored during the season five finale, in which a frame story surrounded the plot of the episode tracking the Impala's history from its manufacture, through several previous owners, up until the present day. According to Chuck Shirley, the brothers have "made it their own", and they are shown as kids sticking an army man into an ash tray that remains there (Sam), putting blocks into the heating vents (Dean) and carving their initials into the car. The Impala later proves important when seeing the old army man allows Sam to overpower Lucifer during the final confrontation. According to Chuck, as they have the Impala, the Winchesters never consider themselves truly homeless. In the seventh season, after two Leviathans go on a killing spree in an identical Impala, Sam and Dean are forced to put the car into storage and use various other cars as they are too identifiable with the Impala. Dean later pulls it out of storage to confront Dick and has the demon Meg crash it into Sucrocorp to create a distraction. During season 8, Sam and Dean are once again using the Impala as their car.
All of the cars used in the show are stock 1967 Chevrolet Impala four door hardtops. They feature Chevrolet small-block engines, recolored interiors, custom seats, and nonfunctioning radios. Other than the one used in the original, all of the Impalas had to be painted black for the series. One of the Impalas used features a detachable roof and doors for up-close shots, and is capable of being separated in half.
