100% serious. I didn't get much out of the video. Just sounds like another LS engine with an exhaust on it. With all the carrying on and comments, I was expecting more from it than what I saw. Like, WOT pass by, sliding around curves, rapid accel/decel, etc. Not a short clip of a couple curves, an unstable rear end and some chirp.
