Hello Kane. A HQ Kingswood station wagon is pretty rare. It depends on what you want to do with it. Restoring it to original can take months to find parts and such. Plus if it is rusty as hell you will need to get that done and then get the colour code for the ORIGINAL paint job, and respray the whole thing.
My opinion, I would keep it and do it up for a bush basher. Not worth the money or headache
