thanks alot every1.
The pre 06 GX models were different in alot of ways compared to the facelifts.... They used the 5L-E and 1kz-te engine, which was later replaced by the 1kd-ftv D4D. The interior trim was different, noticeably the unavailability of passenger airbags. however, do not confuse the interior quality of a prado to that of an xli 
its possible. thats y, its better to check before hand if the car is equipped with a passenger airbag.
