In similar cases the RAC have refused to do it on the grounds that it is merely transport and not an emergency. It will have already accumulated recovery and storage costs which may well be more than the value of the car.
If you involve your insurance company they will load your next premium. My advice is to do a deal with the recovery people and scrap it. Buy another cheap car and transfer the insurance without telling them that the first car was stolen.
Maybe He had notified the Insurance company as soon as he noticed it was stolen?
