I'm currently in the process of getting my Triton repaired after being rear ended in slow moving traffic. Unlike a claim on car insurance, I am having to do all the leg work myself. I have to obtain quotes and submit them for approval. I also have to claim my excess and uninsured losses from the other insurance company.
I suspect it will take months rather than weeks. Unlike a car, pattern parts are not readily available and new parts are expensive. The quote will no doubt be contested by the other insurance company, adding to the time and hassle.
