They had the parts in stock. I spent a lot of money here in parts. They lent me the scan tool and printed out my trouble codes. They also showed me how to clear the codes when I finished. The interior was well kept, and the front parking lot was clean. I normally buy my parts via Rock auto but when I'm in a pinch I tend to go to O'Relly's vs Auto Zone.

Plus she was very friendly and kind, which is why I am rating this store 4 stars. We are pretty much useless in maintaining or anything to do with our car, other than driving it, so we were very, very grateful for the help.

If there was an option for negative stars, Granite Motors would deserve it…read more We brought our daughter's 2016 Buick (with give or take 75,000 miles) into their service department because the check engine light kept coming on. The service writer told us the turbo was the problem and that it was covered by warranty. We were shocked, so we asked THREE different times if he was certain. Each time, he confidently reassured us it was covered. Based on that guarantee, we agreed to move forward and even requested pricing on additional maintenance. By Monday, after hearing nothing, we called--only to be told: "You're going to be upset with me." Suddenly, the story changed. Now the turbo wasn't covered. The excuse? He "fat-fingered the VIN number." This wasn't a one-time slip-up; it was repeated misinformation given three separate times. That's not just sloppy--it's outright negligence. Even worse, the service manager and dealership manager admitted fault, yet the best they were willing to offer was a measly $230 off labor. Then, instead of making things right, they started avoiding us altogether. At one point, their response was literally: "Well, you're more than welcome to come and get your vehicle as we don't have to do the work." That statement sums up the culture at Granite Motors: zero accountability, zero integrity, and zero respect for customers. They admitted fault and still refused to honor their word. That's not customer service--it's a bait-and-switch backed by arrogance. We will never do business with Granite Motors again, and we strongly urge anyone considering them for sales or service to take your business elsewhere. There are plenty of dealerships who actually stand behind their word. Granite Motors is not one of them.
