Our Reviews
Awesome experience from start to finish. I have purchased a lot of cars and this dealer is definitely at the top of my list. There were no last minute "surprises". My wife even commented of the little bags they provide you to help transfer your belongings from your old car to the new one. That was a first!
Everything went smooth from our initial conversation with Jalen all the way through closing the deal with Shaq and followup support has been excellent.
By far the best dealership we’ve been to. Marcus was a pleasure to work with. He will be our contact for new purchases in the future.
Very professional staff! Our salesperson, ROC, was awesome!!! Thank you, Mullinax!
The staff was very friendly and helpful and the process was not stressful and Shaq and staff really was helpful and very friendly and easy to talk to
Everyone that we dealt with at Mullinax Cadillac,GMC was exceptionally friendly and courteous. I would certainly recommend them to anyone.
They were a big help. Explained everything about my new car which was a big help!!
Mr. Willie and Freddie were both beyond amazing during my purchase process. I’ve never had an easier experience. 10/10
We stopped by just to look at cars... Roc greeted us outside. Answered all our questions... We ended up buying a car! A huge thank you to Roc for being so awesome!!!
We were traveling from FL to IL and had problems w/our battery. We called to see if we could get our truck in and Ebony told us to come right in. John K. worked us in the same day so we could get back on the road. Ebony and John as well as the service staff were truly amazing and saved us from having to stay in a hotel and got us back on the road in less than 2 hours!! We are so grateful for the service dpt at Mullinax Montgomery!!
