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).
The trunk holds an amass of weapons that are modified and crafted to aid The Winchesters in their hunting activities. Dean refers to the Impala affectionately as "Baby."
