I arrived shortly before lunch to get an oil change and tire rotation, but I didn't have an appointment. The person that greeted me said they could do the work but it might take up to an hour and a half. That was no problem for me so I was shown to the waiting area.Although it took about two hours to complete the work, the waiting area was not crowded and the wait was not a problem. The service writer let me know the vehicle was ready and asked how I was going to pay. Apparently, the credit card system was down, but they offered another way to pay with my card. An email with a payment link was sent to my phone and the payment was completed quickly.The overall experience was great, even though I had to wait a bit longer than expected. Everyone I spoke with was polite and knowledgeable. I don't think I could expect much more.

Service was very good. Susie (service representative) went over and above to make sure that anything that could have been taken care of under warranty was taken care of. I was keep in the loop of the progress of my service. I was not pressured into getting services that is didn't want at the time but was made aware of my vehicles service needs.

We had a wonderful experience at the Bob Mandal dealership! Our salesman was so nice and very knowledgeable on the vehicles. Everyone from sales manager to finance guys were awesome. I have to say it was the least painful car buying experience we've ever had! The dealership was very clean and someone was constantly working to protect guests against Covid-19. All in all great experience

Bobby Gordon, Jamie Minkins and the entire Mandal team are the very definition of excellent customer service. From the time my appointment was booked, until the routine maintenance was complete, they kept me informed every step of the way. In addition to routine maintenance, they even took time to explain the issue with my DVD head rest set; most dealerships would have fixed it, without explanation. I can honestly say, I have never experienced such a level of caring and honest from a dealership. I am glad that I am a part of the Mandal family!

the finance paperwork did not show downpayment requested on the on-line credit app but we moved forward anyway with the purchase and without amending in the interest of time. Also, the car was not perfect as we discovered scratches on the hood of the car after we got home. The detail department said it would need attention from the body shop but no resolve has been clearly defined.

Nicest people you could ever meet to purchase a vehicle. We have 3 from Mandal and wouldn’t go to anyone else.

My mother recently purchased a vehicle from Mandal and raved about the level of service she had during and after the sale. She was right. Mandal made the buying process as quick and easy as possible - something that was very important to me. Jim C. was an exceptional salesperson (also recommended by my mother) - he was very friendly, but straightforward. I felt like he wanted to help me find exactly what I was looking for, rather than just make a sale. Would definitely recommend this dealership (and Jim C.) to anyone in the market for a new vehicle.

Good afternoon, My experience at GMC was GREAT from start to finish.  I am very satisfied with the service I received.  Setting up the appointment was smooth and welcoming.  Upon arrival the young lady was very polite and professional.  The environment was clean and seating was adequate for social distancing.  Checking out was a breeze and the staff was very knowledgeable about my car and answered all my questions and concerns.  Thanks and I will be returning for repairs soon.
