i wouldnt be surprised about the insurance company. they screw them down after they award them the job. thats why most people use 2nd hand parts with repairs. insurance companies encourage it.
Just cars tried to tell me the that consistant quotes of $2900.00 for a genuine supra bonnet is false and they could get them for $400.00. I spoke to contacts at Toyota to tell me what their buyers cost was without margin and we could only squeeze it down to $2100.00. After i sent JCI a letter they then agreed to it but went straight to the repairer and told them they would provide the bonnet and deduct that cost from their quote. We've had similar issue with my boss's audi Q7 that was resprayed after some peasant keyed it.
Remember KMF is a single man operation. Its a small workshop so it could be just bad timing. thats why i would say wait and orgainse a quote first.
Out of all the shops of dealt with along the way he so far takes the win for communication, pricing and results. He is very honest even if something goes wrong!
