I bought my car in for diagnostic review due to an issue
I bought my car in for diagnostic review due to an issue with loud roaring noise when I drove my Buick Verano above 50 miles an hour. Cristina was my service representative and she provided excellent customer service. Cristina smiled when she created me and made me feel comfortable as she listened to me. I felt she appreciated my business and was interested in resolving my car issues. She called and texted me on any developments, as well as returned my calls the same day. I was very pleased with her friendly and competent service.

Great dealership.
Great dealership. Bought a GMC Acadia from this dealership and the sales was assisted by AK Mirabi who was very much customer friendly, customer focused and very much helpful throughout the sales and vehicle handover. His assistance for the sales is truly appreciated. Karime Nava was the finance manager who ran through the finance process and documentation and she was super helpful getting the great deals on the APR and extended warranty packages for a great deal. Truly appreciate her assistance on the finance side. Had a great experience with the Group 1 GMC North dealership during my Acadia purchase

My overall experience with Classic Elite was very good! The people were great. My service advisor was Holly Widman and she was great to work with. The only drawback was the time it took.
