Our Reviews
Great customer service, they are very helpful and friendly. Never had a problem with ghem
October 2024, I went to Mandal Buick GMC knowing exactly which vehicle I wanted and I was pre-qualified. They didn't use the companies I was pre-qualified with but instead caused 3+ hard inquiries then tell me GM Financial offered me the best interest rate at 8.45 percent. I asked if they are sure because I've never received anything but the best possible interest rate and they insist it was the best. I now know better because only 6 months later I refinanced the vehicle and currently have a 3.49 percent interest rate. I should have taken my dad's advice as he said if they give you a good deal on the vehicle they're going to jack up the interest rate and apparently that's what they did in my case because my credit score nor anything else about me changed in 6 months. In addition to this I regret that I purchased my 2024 GMC Terrain from Mandal for several other reasons the biggest being they have made it very uncomfortable for my husband or I to go there. During my purchase they made it as if I had a choice to get Auto Butler or not but a couple months after my purchase I tell them I do not want Auto Butler. My receipt says I paid $1,099 for the auto Butler but when I asked for a refund they claim they increased my rebates for Auto Butler to be free to me. This was not explained and I do not have anything showing I was given a rebate for $1,099 on Auto Butler and they claim that I can't get a refund because it can't be taken off. As far as I know it was never applied but if it was the $1,099 is supposed to be for every 6 months application for 5 years which is what I do not want and it is not right for them to not refund me. Additionally, if I did decide to use it, my husband and I feel highly uncomfortable going to this particular dealership and it can only be used here. In addition, when I bought the vehicle, nobody told me that I cannot get it serviced under warranty at the dealership that is closest to my house. Several months after purchasing, I attempted to bring it to the dealership closest to my home and was told they're not allowed to do warranty work on my vehicle due to a contract they have with the selling dealer to not take customers away from each other. I said well your refusal to work on my car under warranty is definitely not going to force me to bring it to the selling dealer because they have made it so uncomfortable for me to do business at the selling dealer, I'll drive an hour away to go to a GMC dealer in another state or drive an hour to the next nearest GMC dealer within my state.
KD MADE OUR PURCHASE OF THE 2025 GMC TERRAIN THE MOST PLEASURABLE EXPERIENCE WE’VE EVER HAD. HE WAS KNOWLEDGABLE, COURTEOUS AND EXTREMELY HELPFUL.
We waited for our car. They never came to tell us it was ready. Went and ask when we seen our car sitting outside the window.
Excellent rebates and fair prices. With rebates you need to finance through GM however the deal i got on my new sierra was way to good to pass up. Plus, they offer great trade value. This dealer is all about selling volume and not in the business of Deception. Sales team is great
Great service, very knowledgeable throughout the entire process. Definitely 10/10 experience on my 1st new car purchase.
KD made the car-buying process easy and enjoyable—outstanding service and we love our new car!”
Laken was great to work with. She was understanding and made the overall process easier.
It's where I bought my 1500 truck so I had the service done on it and my 300
If my experience wasn't the absolute best this would not be my 3rd vehicle purchase. I appreciate the staff.
It was a truly great experience from first phone call to picking up my vehicle.
Fast, easy, and painless. Great prices and trade in value. I love everything about them
I had a very pleasurable experience recently replacing and upgrading my GMC Sierra 1500. Aiden Harrison and Patrick Magee were terrific to work with. I would recommend them highly!
Outstanding Dealership . Every detail was covered by our sales person and our financing advisor. Great job guys.
Professional service as expected with a huge smile on their face at that! Thanks for a wonderful service department!
