Is it necessary to get my Volkswagen Passat serviced at an authorized dealership?

I've been hearing mixed opinions about whether it's worth it to get my Passat serviced at an authorized dealership or if I should just go to a regular mechanic. What would you suggest and why?

It's always best to get your Passat serviced at an authorized dealership. They have the specialized knowledge and training to ensure that your car is properly maintained. Plus, they have access to genuine Volkswagen parts.

I've had my Passat serviced at a regular mechanic and it's been completely fine. Just make sure they are experienced with Volkswagen models and use quality parts.

I personally always go to the dealership for my Passat services. They have a better understanding of my car and I trust them to take care of it properly.
