The Impala is Dean Winchester'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.

Altogether, at least nine separate 1967 Chevy Impalas were used in filming Supernatural, including one of the original iterations which was totaled at the end of the first season. While in the show, the car was rebuilt, the actual stunt car was completely destroyed.

The narrative is made up of two stories, roughly equivalent to the first two chapters of the Book of Genesis. In the first, Elohim (the Hebrew generic word for god) creates the heavens and the Earth in six days, then rests on, blesses, and sanctifies the seventh (i.e. the Biblical Sabbath).
