The Impala, of course, has all the things other cars have… and a few things they don’t. But none of that stuff’s important. This is the stuff that’s important: the army man that Sam crammed in the ashtray - it’s still stuck there. The Legos that Dean shoved into the vents - to this day, heat comes on and they can hear ‘em rattle. These are the things that make the car theirs - really theirs. Even when Dean rebuilt her from the ground up, he made sure all these little things stayed, 'cause it’s the blemishes that make her beautiful.
