I test drove a 2016 Edge Titanium with the 301A package. I drove it home to show my family and my teenage son felt like the roof was too low. He's only about 5'7" so I was surprised. It may seem lower than it really is (he still had room above his head) but I went back to the dealership and it looks like the Vista roof takes about 3 inches off the height in the back seat.
I just wondered if anyone had issues with passengers in the back with the Vista roof.
