Authorized MINI repair shops vs. general repair shops

[ejel]

My Mini Cooper had a minor accident where the other car backed up and bumped into my car. The adjuster estimated that the hood has to be replaced, and repairs are required for front grille, head lamps, bumpers, amongst some other parts.

My question is: is there any difference between authorized MINI repair shops and non-MINI repair shops in terms of repair? Since the closest MINI shops is ~3 hours away, I'd consider bringing the car to some nearby shop if how they do it is identical. However, I have no problem bringing it to a MINI shop if the work/parts is supposed to be better.

Your input is appreciated.

Retain your paint warranty.

If the car is less than 4/5 years old, I would only go to authorised MINI repair shops.

Thank you for your input. Do you mind elaborating on what are the major issues that you would prefer authorised MINI repair shops?
