The way buying a vehicle should be. From sales, test driving, trading a vehicle, to financing, the process was great.

DealerRater Apr 24, 2025

I had an amazing experience. Jim and Tony were great! They were really patient and I wound up in a new vehicle

DealerRater Apr 24, 2025

I had an appointment for an oil change and tire rotation and it took over 2 hours to complete. HOWEVER, they recognized how long how I had been waiting and did not charge me for the service. I did not purchase my vehicle from Mandel but they will be my go to service department.

DealerRater Apr 21, 2025

Susie is by far the best service attendant that I have ever experienced. She keeps me updated and informed. She doesn't double talk or seem fake. She seems to have a genuine approach to customer service that is refreshing.

DealerRater Apr 20, 2025

We bought a used car here and the experience was very professional and pleasant. Thanks

DealerRater Apr 19, 2025

Always the best to deal with, specifically Daniel and Patrick, and Jamie in service. Clean and very professional.

DealerRater Apr 19, 2025

No complaints at all. Customer service has been excellent ✅ I’ll make the drive every time

DealerRater Apr 19, 2025

The experience at Mandal Buick GMC pre and post sale was exceptional!! Truly appreciated everyone from sales to finance!!

DealerRater Apr 19, 2025

Most unprofessional non- organized un trained bunch of people. No one knows what xxxx is going on. I have bought several cars from there but never again.

DealerRater Apr 15, 2025

Honest and fair. Willing to work with you. Felt they understood where I was at in the price point

DealerRater Apr 14, 2025

Overall I usually have a good experience at Mandal but this time I had to wait 2 and a half hours for a simple oil change even after I had an appointment and showed up 30 minutes early. The did give me a discount for my trouble which was nice and unexpected.

DealerRater Apr 14, 2025

Worked with Jim Crampton and Mr. Tony was a great overall experience. I will highly recommend them to friends and family.

DealerRater Apr 14, 2025

Always on time. Good communication with the staff and a comfortable waiting area. Im a repeat customer three times now.

DealerRater Apr 13, 2025

Thanks Bri and Tony!!! Plus the others who played a part in me getting my car!!! Thanks for making me comfortable!!! I Love my car❤️

DealerRater Apr 13, 2025

I would have given a 5 but the wait time is way too long. I think 8 hours is excessive
