<prompt> Human: My car how been in its second major accident. The first time they repaired the car it took over 3 months to get the car back and the work completed was poor no coolant almost dry, window had a gap so when I drove over 80km it whistled, tubes were not tightened and they popped out etc. My repairer has written off the car because the vehicle will not be safe to drive no matter what work is done. RACV still want to repair the car. They are pushing the matter because I have an agreed value, roughly 10k more then if I was to sell the car.What can I do to push them to write the car off?Edit: it has been over 5 weeks since I made the claim  <response>: Legal expert required but my opinion would be the repairer is the subject matter expert, they fix cars as a profession, the insurance company make money from people that spend more on insurance than they claim. They may be able to seek a second opinion but then so could you
