I liked that car and what they did to it, but there are several things that bother me in that video.
First of all atleast 2/5 of the length are commercials, and the way those mechanics advertize the products, is awkward. It also seems overly dramatized, and doesn't look very well produced.
One good thing about that is that they give enough information about what they are about to do, and how it affects the performance.
