Hello Mark,
I own a 4/4 Sports since a few weeks. I don't think your stature will be much of a problem. But than, you anyway want to test drive the car before you decide to buy it.
Even so I am just shy of 6 feet, I have rather long legs. I find the leg room in the 4/4 comfortable enough, but the steering wheel (the standard type ex-works) has to in the upper-most position to avoid permanent contact to my knees.
