Place it right at the reveal cut in your edit, after a short build-up shot of the car approaching. Follow it with the bruh sound effect for a second reaction beat, or keep it solo before cutting to comments or close-ups.
About this sound
This is a two-second German voice clip of someone blurting out a shortened, colloquial question about what kind of station wagon that is. It sounds confused and amused, like a spontaneous reaction to an odd car rolling into view. The disbelief feels instantly relatable, which is why it works as a quick baffled reaction in car memes.
