176k miles. It's had a very long list of maintenance done in the last few years but nothing major except the 5-spd swap since it was originally an auto. It does still have the 3.46 rear end which makes the revs pretty high on the highway but that's a problem for a later time.
The PO did a head job and HG on it a couple years ago and has done a few track days with it since and during my test drive, it seems solid. My goal is to swap the entire drivetrain out for either a ZHP M54B30/6spd swap or a S54/6spd swap but I'm needing to dig into it further before I decide which to go with. I had a ZHP years ago and really liked that motor. I'll be buying a full donor car for whichever swap I do but that likely won't happen this year as I really don't have time currently to take on that kind of project right now with our infant.
I did stumble across this earlier today which is the same wagon when it was for sale ~3 years ago.
