On the plus side, if you can talk him down a bit and the driveline and hang-ons (radiator, exhaust etc) are all good it may be worth buying to then stick all that stuff into a 6cyl HJ ute or van. Looks like you have good seats, dash and wheels too. It has a decent tailgate on it too if the new car needs it. Onsell the HQ front, GTS guards, doors and you'll even sell the HQ as a rolling body for close to $1000. Just another alternative to think about. Some Torana hatch owner will want the T-bar handle.
