Hi lawyer80, firstly ignore Pablo's comment (sorry Pablo you're under qualified for this question
). I'm 6'5 1/2" in bare feet and have driven all the modern Ferrari's as well as a lot of the older ones. Some are good others not so.
Things to consider are not just height but leg to torso ratio. Not everyone is the same so this makes a big difference in the different cars. Also you need to drive the cars not just sit in them because fitting is one thing but your lines of vision are another.
In saying that, you will not have a problem in the FF and F12 which have loads of head and leg room plus a more spacious cabin than previous models like the 599. The 458 Italia is a sports car (as apposed to a GT car) so has a more cosseting and focused cabin, but with race seats (which are more comfortable IMO) is very comfortable for me. The Spider feels a little tighter but it's not so much a headroom issue but where your eye-line is with the top of the windscreen which is slightly different than the Italia.
So take a few test drives preferably in cars with race seats, play around with the positioning and lines of vision and go from there.
If your set on a spider then see how you go, but if not the F12 is the car to go for IMHO as it is bigger, faster and cooler (is it a GT or is it a sports car?) than the rest. Will I follow my own advice......well no, the 360 spider will eventually make way for a 458 Italia with race seats
.and from there who knows.
