So, I happened to pass by a local Mazda dealer and tried the CX30 for size. Oh dear, the headroom is not much better than the 3. I'm 6 feet 2 and my head was only about half an inch below the headliner and this was on the seat at it's lowest setting with a reasonable recline. Going over big bumps or speed humps my head would be hitting the roof. The CX5 is the only Mazda I can fit in for height now.
