Eddie was very thorough in explaining the 45,000 mile service necessary even though I only had 39,000 miles on my vehicle. I have complete trust in this GM dealership.

Eddie did a great job and looked after me well. In and out in under 90 minutes after a multi point inspection, oil change, tire rotation and car wash.

I have been dealing with Performance GMC for close to 3 years now. Nothing but great service with both Service & Sales departments.

Junior was fantastic - start to finish! He kept me in the loop throughout the process and was very warm and professional. Car was fixed promptly and even worked with my schedule to support pick up. Such a pleasure and thank you so much!

These surveys are annoying, I have purchased your product, I have used your services, isn't that enough. It seems you hold your dealership and your employees hostage and your customers hostage by requesting to complete these surveys
