Hi Frank, As mentioned by others the Maranello's are among the best for the tall guy's and at 6'5" I should know. Plenty of leg room and not hard to find a good position with the combo of adjustable wheel and electric Daytona's. The carbon race seats are a touch lower giving more head room but have less adjustability.
For me, I wouldn't go for a GTS in the 308/328 because with the roof off it restricts legroom when stored. No problem driving the berlintta's, although I've been told I look like a "bear in a bottle"! 355 and 360 are roomy at head and shoulders although the legroom is on the limit, another couple of inches would be better. The F430 solves that issue and I find it great, although wearing a helmet in a Scud with the legal roll bar isn't too comfortable. The 599 is similar to the Maranello's but the best I've driven is the FF by a mile.
Current Fcars: 360 Modena
Gone but not forgotten: 360 Spider, 575M, F430.
Other stuff: '71 Holden GTS Monaro, '80 BMW Alpina B9, '74 Porsche Targa, Caterham, MB CL500, Land Rover Discovery.
