This dealership does not care about their customers. Once they get the sale you’re pretty much not important anymore. The service department is even worse. They did not reset my tires after rotation w Once they get the sale you’re pretty much not important anymore. The service department is even worse. They did not reset my tires after rotation which resulted in me almost having an accident and then took zero accountability when I brought it to their attention. I would never buy a car from here again. The service was bad but the car was even worse. Less than 6 months I began to have countless issues. With tires, breaks, and my check engine light turned on as well. But General Motors decided on their own that this didn’t pose any safety issues. Please don’t buy a car here. It really was a terrible experience More

Advertised false price, tired to add $4k once we arrived. Spent 8-10 hours before settling on advertised price. We were promised 2 keys then lied to and ignored fo1.5 months. Finally promised 2nd key only Spent 8-10 hours before settling on advertised price. We were promised 2 keys then lied to and ignored fo1.5 months. Finally promised 2nd key only to have my wife drive 1.5 hours to pick up key and have 1st free oil change done. 5 hours of being told Sierra can't find paperwork before key FINALLY handed over. My father raced Covettes with factory sponsorship in the 50's & 60's and I have been a GM guy my whole life. Terrible customer experience. More
