I think you're all trying to read too much into it! It looks to be EXACTLY what the ad says it is, ie: a Kingswood Ute with GTS dash, guards and a Prem front.
It also looks to have been resprayed in 2pack and having Prem wagon sill strips is just an easy way to hide the fact that the sills are either stuffed or are full of bog.
At $4,000.00 it is not a bad price if the car lives up to the photos.
