Disco II purchase

I have been researching plenty on Disco II's in my area for purchase for my girlfriend.  DiscoMike, you have been helpful before so I was wondering your thoughts on this vehicle.  I am hoping to negiotiate for a better price, is there anything you can offer me on this vehicle as leverage for this.  Also, I was planning on pulling codes on this after I test drove it but am having a hard time finding error codes online.  Can someone point me to a site or something with the listings?

Here are more pics of this Disco.  Also My girlfriend REALLY want to 3rd row seating option, so that a factor in this otherwise the options would have been greater.

Can I ask why she wants the 3rd. seats?
Not there is anything wrong with them, they just limit the amount of rear cargo room.
How many miles on this truck?

She often sits for a few kids and sometime her and a few other will take the kids out. She has a child as well. She doesn't want a minivan, but like the ability to throw some more people in the car. The 3rd row seats flip up or something right? Yeah, we know it limits the options but she is willing to deal with certain things. She definitely wants black ext and wants 3rd row seating. She loves the look of the Disco's and I guess her friend has one too and she wants one as well. Plus the 4WD is also a requirement.

This one has 73k on it.
