The Impala is Dean's trademark black 1967 Chevrolet Impala. It was passed down to him by his father, who bought it in 1973 after a future Dean convinces him to buy it over a 1964 VW Van in the episode In the Beginning. According to Dean the car has 327 Engine and a Four Barrel carburetor. It bears a Sedgwick County, Kansas license (though their hometown of Lawrence, Kansas is actually in Douglas County) plate KAZ 2Y5, a reference to Kansas, the Winchesters' home state, and 2005, the year the show premiered. Starting in the episode 2.20 What Is and What Should Never Be, the car sports a new Ohio license plate (CNK 80Q3).
