Ian firstly sorry about your mishap

Secondly you need to inform your insurance company. Tell them the vehicle has been damaged by the dealer and that the dealer are sorting it. It will not affect your premium or no claims, but if there are any issues with the repair quality you can then get your insurance company involved. Also should YOU have an accident in the vehicle at a later stage, and the insurance company find out the vehicle had an undeclared accident in your ownership they may decline to pay out.

Thirdly, find out who the dealer are using, qualify them and if you are unhappy then tell the dealer where you want it repairing.

My local dealer uses an independent body shop which is fully BMW approved and they are absolulety superb ( ok twice for me )

Let them assess, and once you know the full extent of the damage and repairs then the time comes for a calm adult conversation with them about the way forward

If the repairs are done right, following a low speed shunt, then you should never be able to tell
