I brought my gmc Acadia in here for warranty work. They performed an inspection on it. So, it was already on the car hoist. They got for 189 dollars for "looking" at my exhaust system. Hell I could've looked at it myself. Beware of what you tell them to look at because everything is an additional fee

Went to get car worked on before warranty expired and everyone was great and Taylor kept me informed throughout the process. No complaint and car is running great.

Pierce alwine was very helpful and honest

The technician is always in contact as the services are being done with my vehicle and they take pictures and videos of problematic issues they come across and ask if they want them taken care of and if it is OK to let go for time being but needs addressed at a later time. Staff is very courteous and friendly and lets me know when my services are completed. I've been to other dealers in past but no one can compare to Gurley Leep GMC service department. Best in the business, they will always have a customer with me!!!

Service employees were nice to work with. I went in for a recall on my driver side air bag and my entire car got inspected too, all at no-cost.
