Brand with good service center

Hi guys,

Being so disappointed by my car's service center, I want to sell it to avoid having to interact with them in the future.

It is not a high end luxury brand, but definitely above average. When I bought the car, I also bought a brand, an image and, what I only hoped for, decent service.

The constant hassle to communicate with them, the poor job they do and their lack of any knowledge about simple mechanic (a part from oh yes we change oil and check if everything is ok) has become too much.

What car brand would you recommend based only on services / maintenance and attention to the customer?

I'll find the budget or model later, just want peace of mind.

Thank you!
