The 1967 Chevrolet black Impala had a breakdown and since you were in the middle of nowhere and it was pretty late at night you, Sam and Dean decided to just stay there until the next morning. Dean called Bobby too just to let him know and maybe he'll send help.

Now all three of you had managed to get into the cramped space of the backseat, since it was probably the warmest and most comfortable option at the moment.

Sam was half leaning against the car window with you laying against his chest. His arms were gently wrapped around your waist to keep you from falling while Dean's head was resting on your lap. One of his legs was hanging down the seats, like his arm. It wasn't that comfortable but it will do for the night.
