Seems like I will have to take this matter further. In accordance with Toyota's repair guidelines is the structure of the car is bent then those items affected will be required to be replaced. My insurer has notified me that they repair cars to industry standards, however under the NSW Fair Trading Motor Vehicle Insurance & Repair Industry Code of conduct which is put in place by NSW legislation must comply with the following: "Having regard to the age and condition of the motor vehicle, repairers will carry out repairs (and insurers must not require them to do otherwise) that: *are in accordance with the manufacturers' documented technical specifications, including those supplied by other industry recognised agencies or authorities, or any lawful mandatory specifications and/or standards, or *use methods that are consistent with vehicle warranty conditions, or *in the absence of the points above, are in accordance with accepted industry standards and practice." So basically there is a manufacturers technical specification which states "Structural parts are designed to perform in their original shape. If parts are deformed in an accident, or if the deformed parts are repaired and reused, the parts may be unable to perform as intended. It is necessary to replace the part where the kink has occured." There are a number of compenents that are high tensile steel in the vehicle and the manufacturer states that they should be replaced if damaged. I think I have cought the insurer off-guard as they have notified the smash repairer not to commence repairs and they are going to be in contact with me to discuss the matter further. They did mention that they were going to consult their technical staff (who to my knowledge do not exist anymore) and they were going to consult Toyota on the matter.
