hmm, id have to say id go for a jap spec s15....they are sex on wheels. id only get a 34 if it was a GTR.
edit: my mate is lookin at s15's, we chekd one out in a car yard...he got into his comfy driving position, and his drivers seat was touching the bak seat. so basically, he'd have room for one peron in the bak. they are small...if u are really goin to need the room taxing ppl around then 34 is probably the wiser choice. but if ur short, it should be fine, hehe. personally, i dont care about who i can fit in the car, id just get the car that i wanted.
