Our 2011 VW Golf was brought in to a local panel beater for damage as a result of an accident - the damage was cosmetic only, we've been driving around with it for months before getting it fixed. On the day we're supposed to pick up the car, the repairer told us the car wouldn't start anymore. An electrician was brought in by the panel beater as his initial diagnose was that it could be a sensor issue. The electrician couldn't find anything. The car now sits at the panel beater, waiting for us to decide what to do. The car is 4 years old and never had any issues. NRMA said we have a few options:
1) We can get it towed to one of their service centres
2) We can select our own repairer and get it towed there
NRMA told us that if the damage is a result of the accident, they will cover it (unlikely since it's been months since the accident).
If it's negligence because of the panel beater, they are happy to mediate but that is about it. The other possible outcome is that it's normal wear and tear (which I find hard to believe) and that it will be assessed as such. I'm not sure what to do because our own mechanic (that normally does our servicing) is not available for another 10 days. Also, NRMA said we have to pay for the car to be towed away unless their assessor comes to the conclusion that the current fault is because of the accident (again, unlikely IMO).
Any advice on what to do? Obviously, I prefer the car to be brought into a fair repair shop that won't charge the world and, if it's related to negligence on behalf of the panel beater, will help me showing the NRMA and the panel beater accordingly. Also, we don't have car rental insurance so every day without a car costs us money.

Have you asked what the panel beater thinks it could be?
Panel beaters can be dusty and dirty places. I would first think that it could be an electrical issue somewhere caused by dust particles. I know you had an electrician look at it, but still. If the car required a respray in or around the engine bay, that could also contribute to it not starting.
If you can wait, take it to your mechanic. If not, go with NRMA; after all you do pay them a yearly fee. Once you find the problem, then decide whether the panel beater has contributed to the fault.
I would also ask the panel beater to note on the receipt of work completed that the car does not start upon pick up.
