Motor Trend already has a similar segment on PBS for years. It mostly covers vehicles that are fairly common in the US, to keep the viewers interested. There are many other similar programs on SPEED channel that cover expensive and exotic automobiles around the world. I don’t remember seeing any such program on the big 4 networks (NBC, CBS, ABC & FOX) though. May be NBC is trying everything they can to gain more primetime audience; it used to have the largest primetime audience on Tue, Wed and Thu. These days, Thu is the only day they can boast of such a feat.
Personally, if they put the show on, I will probably watch it. In the US, most people watching these types of shows are usually from the Midwest; the big truck buying crowd. Let’s see if NBC comes up with a correct timeslot to make it a reasonably successful show.
