mate i am 6"1 and i find the size no worries!! the only thing is maybe leg room but only annoying if driving 1000's of KMs. i also have 6x9 in the doors i and i dont feel cramped..... if you are goona buy a ute diffentaly get rid of the big clown steering wheel put on a nice small steering wheel from super or autobarn, this will free lots of room up.

my head doenst get near the roof either, i find the ute to have good amount of room unless you are say 150kg

p.s i am about to put a boxed sub in, so there is plenty of room for lifes little luxuries
