One photo. Almost no info. As far as I know there were never any Super High Output Taurus wagons offered from the factory. So this has to be a conversion. https://seattle.craigslist.org/kit/cto/d/olalla-1994-ford-sho-taurus/7250773750.html
I don't remember a SHO wagon either but it sounds like a good idea. If reliable, this could be fun for $2,200.
Coming from the Great Northwest, you would hope this wagon would be rust-free (or, comparatively rust-free compared to the rust belt). An SHO engine in this wagon would be a hoot and-a-half.
There were no SHO wagons. There have been a few first, second, and third generation conversions through the years. Judging by the crap in this guy's yard and the lack of pictures and description I have a feeling most people would be pretty disappointed when they went to look at this.
Maybe he should have waited for the clear coat to finish peeling so the hood and roof looked smother, that wet picture makes it look really rough. But for $ 2200 one might luck out and find a gem under there,
It's possible it was done properly. Somebody did take the time to swap the SHO front bumper cover and headlights. I just look at that picture and envision drywall screws holding interior panels together and who knows what kind of mess under the hood.
