I find it hard to watch the Car Show without wanting it more to be like Top Gear UK, and I think many of my criticisms of it are, well, because it's not TG. I know this is kind of an unfair criticism, but TG is realistically the benchmark in this genre.
I think the Car Show is good but I'd like to see longer, more fully-produced segments - the show feels like a patchwork of a bunch of tiny bite-sized pieces and it makes it feel long at times, without much in the way of depth. Some of the individual segments are also not produced in an entertaining way (e.g., the Dan Neil dirt racing piece). I would like to see them mute the audience when they play the pre taped bits - it sounds like a laugh track.
All of these criticisms aside, I do like the show and hope it's successful enough to make it for a second season.
