That's so funny.
I am 6'8" and I just waiting to receive my MINI convertible.
After trying so many cars, I had two options. or go to a hi-end very expensive car like BMW 5 or 7 series, Audi A6 and A8 or big SUVs. I tried the MINI after a friend said that I would fit. I never believe him, but after I tried I was impressed in how well designed the car is.
The funniest thing is to see the dealership sales people seeing me asking for a MINI. They said I was on the wrong dealership and they were amazed as I was to fit so well inside.
One thing I noticed is that the hard top with sunroof is small for me. but without it is fine. other thing is the convertible is great headroom with the top up obviously.
