The P5 has just the right combination of all the things required for tall drivers. Just like slug420 said.
The steering wheel is right in front of the seat, you be surprised how many cars it isn't, and it is small and lifts up out of the way. The rails could maybe push back one more click but its still manageable.
The seat cushion height is adjustable, something you never see on compact cars. Making the back of the seat lower and the front higher seems to work for me. It gives me the needed head room while still supporting the lower part of my hamstrings.
I just got back from a 4 hour trip to Burlington, VT. I could have gone the whole way w/o stopping I was so comfortable, but I was using the cruise control so I could rest my right leg.
My only complaint is that I can't seem to get the seat all the way back when the back seat is down. (and yes i did flip the bottom cushion and remove the head rests).
