Usually you hear do your homework before making purchases like this,
in this case it's along the lines of a research paper.
Gotta check everything, ensure maintenance history is up to par.
At that mileage about everything thing that can possibly be changed should have been changed already.
In other words the list of items changed is probably longer than the list of items not changed.
And in a vehicle like this we're talking even the drivers seat. There could be some serious wear so it may or probably needs to be changed.
These vehicles last very long when taken care of.
