When it comes to buying a car, one can only do so much research. A lot of the trust and work lies with the dealer, and consumers take a leap of faith when they choose who to work with.

That’s why Buick dealerships strive to really meet expectations and go above and beyond the call of duty – as evidenced by J.D. Power’s annual Customer Service Index, a measure of dealer service, which put Buick at the top of the list for mainstream vehicles.

This means that in general, you’re more likely to have a positive experience at a Buick dealership than elsewhere. You can check out the rest of the list here. As you can see, a few luxury brands top Buick, but Buick reigns supreme in its class.
