Hi Doug
The big question is - what is the status of the vehicle after it was assessed. Is it classified as repairable or not? Not sure about the rules for in the land of banana benders; but in NSW it can't be re-registered if it is a statutory write off, so that should be the first decision point.
I had a similar situation after hitting a roo with our VY SV8; similar damage just to the passenger side. When it was taken to the smash repairers for assessment it didn't even get off the truck. They turned it around and sent it back to us assessed as a non repairable write off. I was able to purchase the ute back from the insurer for $300. For $300 we had access to a drivable car with known issues.
From a $ point of view repairing something that bent and that old, on a simple cost v risk basis, makes it not worthwhile. But it all depends on how much love you have for it and how deep your pockets are.
If it is classified as unrepairable you only have two options. Buy another or buy a project. If you decide on a project you have another two options - a shell or a runner. We found a shell and started ground up - but a runner would have been a better starting point. I would recommend that route to you if you can. It will save you teething problems; like I am currently experiencing with computers etc.
I know what you mean about the quality of vehicles around - I definitely ended up with a ute with meth bags under the seat (literally) as our project car. Having said that the body was straight and despite being painted with a paint brush and rattle can the interior was sound and in reasonable order. From there it is just time, money and love.
A bit long winded - but I trust it helps you with your decision.
