Mines a 98 model and yes i don't believe it had 45000km on it when i 1st bought it. Steering wheel and gear knob was very warn.
I've come to live with the fact that any skylines imported from japan does not have genuine KM's, like maybe some do if you can monitor the whole thing from start to finish.
I still need to check my timing belt which is supposedly done at 100 000KM's, i just gotta wait until i reach 100 000kms
