What about the Cirrus SR20/SR22?
I have been instructing on this aircraft and I would say its about the same as a DA40. Both are like an average saloon car. My head is 2 inches above the roof line so some juggling is required. Never had any trouble in a 150 though!
Even with the seat all the way back and starting to tip backwards (which is a rather weird and uncomfortable design)
Welcome to Napoleonic aircraft!
