Hello, just purchased 2006 manual transmission AWD X-trail. Has 175,000 kms. Female owner since 2009 and did "everything that needed to be done, when it needed to be done". Seems it has been taken very well care of. What would you do if you just bought this, could you get fluids flushed and/or spark plugs changed? I can't see any records of any tune-ups like this, just regular oil changes...
