We have Motorweek based out of Maryland. It's pretty good but still a very basic local show. Public television is the only station carrying it and it's not shown on a regular basis. One thing I hate about America is its infernal love of SUV's and pickups. There are all kinds of truck shows on TV soooooo I have to cross the pond to get good car shows.
Plus, and this is a big one, Europe gets so many more iterations of cars that we don't get over here. Other than gas prices, you guys live in a auto utopia.
