Deathproof (both parts) was one WEIRD, screwed up movie(s)... although I certainly wouldn't expect anything less from Quentin Tarantino.
And I noticed the "modification" on the Challenger too when they were playing "Captain's Mast", guess that was the only way they could keep the straps attached to the car.
And when I become President, I will enact a law similar to the endangered animal species act that classic cars
cannot be destroyed for entertainment purposes. They've got CGI now, there's no need anymore to destroy a classic car merely for entertainment value. Would you vote for that?
