I'm not sure if the Honda Repairer at Astoria Honda is an "approved" or an actual Honda repairer. They seem to work only on Hondas anyway, and are based in the dealership service and parts area. Would assume there would be one in NSW that's similar. I recommended them, because for a bump in the door, the amount they wanted to charge me (8k worth! for a bump in the rear passenger door) because they were insistent on replacing everything, and repainting the panels that weren't involved but surrounding the door. Saw their work though, it was clearly up to standard. But the main reason I recommended them was that they charged an arm and a leg, just to screw the insurance company over. I reckon they would charge 30k on OP's car if they saw it. Make them think twice about not writing it off.
