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.

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.

We are so grateful for the service dpt at Mullinax Montgomery!!
