The newer tacoma has more interior room and a bigger engine. You CAN get a 6 speed tho <img src="/forums/images/graemlins/smile.gif" alt="" /> (unlike the 04' where it's auto only for d-cabs). Interior is nicer in the newer trucks as well. I'd take the newer one if i had a family, more room/space, plus it's available with a 6ft bed, where the 04' is only 4 ft....
