I'm 6'5", and my 2017 is plenty comfortable. It more depends on your girth than your height. The mustang's seating cockpit isn't overly wide, so a 6' person weighing 300+ pounds isn't going to be as comfortable as me at 6'5" and 220. At my height, I still have to move up the seat from the farthest back position to comfortably drive with the clutch on my GT.
