My daily drive is around 350miles and have been using 07 G35 sedan, very comfy along with 19@ wheels and aftermakert springs.
Coming to the Z seats just kills me afters the trip mainly on the thighs, they start aching LOL...usually i keep the seat at the lowest mark not sure if thats the reasons and on top of that road noise plus the FI drone on 80-90m/hr speed
for city driving or short trips I love it.
