No idea but I’m 5’8” and I found the seating position in my 355 very odd even with a Hill Engineering wheel spacer. Italians are clearly different to us!
I'm 6'4 and have had 355's, air cooled 911's and two 308's. Tight but not unusable. Modern cars are like limousines by comparison especially V12 Ferraris.
I see all you lanky lugs start at 355s let s see you try out rhd 308 and 328s
Owned both. 308 has more room as the seat sits lower. 328 has a more padded seat which limits headroom. Tight fit but certainly not unusable. I preferred the 308 anyway for multiple reasons.
