ok, for starters, you don't have to find sht unless you have a deal going with your chosen repairer,
HIS insurance company buys them direct from toyota, and who cares how much THEY have to pay for them. i cant believe he claims it wasnt his fault, but admits to "looking behind his chair at the time"
dont stress too much, as it was a work car it is almost certain that it was insured, as opposed to getting hit by joe dunnydore in an Xsomething falcon.
