From 2002~2009 shape is same just cosmetic changes plus from 2002 to July 2005 engine options were 2.7 petrol,3.4 petrol and 3.0D in TX,TXL,TZ and TZG trims were available after July 2005 2.7 was upgraded, 4.0 petrol replaced 3.4 and Diesel engine remained same
The best combo is if you find a clean TZG either 3.4 or 4.0 it’ll be best among all
