CC, C&SC, Octane, AOC News, Jaguar DC News, Austin Healey News, occasional others include Classic Car Weekly, Modern Classics, Classic Cars for Sale etc.
I also think I might cut out one of the first 3 and often think it might be Octane because they tend to feature high value exotics which are not my thing, but then they do have some interesting articles and for the relatively low cost of their subscription I think what the hell.
