Ford Mustang has come a long way in terms of material and build quality, but it seems there’s still plenty of room for improvement! Here’s a prime example for you. This V6 Mustang 2011MY literally starts disintegrating itself as the driver passes 120mph. And at 135mph the driveshaft lets go. According to the uploader of this video it’s resulted in a hole in the metal floorpan, major exhaust system and muffler damage, broken transmission shifter, broken parking brake, broken interior plastic trim parts. American cars eh?
