I second what was said already, and agree that it starts out pretty good, but trails off in the second half. I think you should rework your camera angle, and maybe do it from higher up and or edit it a bit to the sound you are using. I noticed a couple of intersections between the wheel and the body and there is a funky jerk when it gains traction again. Really cool though man. I animated an suv doing the same thing once, and found out that animating things like that by hand are hard actually. But keep pushing it, it looks great.
