I'm just over 6' and heavy build and fit into the Plus 4 sport ok. I would also look at the hood arrangement whether its a traditional hood or easy up hood, as the easy up hood takes up more of the rear parcel shelf, having said that you have to find somewhere to store the trad. hood itself. Whilst the easy up hood arrangement encloses the 3 sides of the rear parcel shelf forming more of a higher barrier to the rear, the trad hood arrangement leaves the rear of the car much more open, lower and more exposed
