Friendly and fast service.
Friendly and fast service. They did an excellent job helping me find a reliable vehicle within my budget. Devante Titus was very helpful and professional and made the process painless.

Let me start by saying I have the AT4 model with the Duramax 3.0L diesel. I had a 2024 Elevation with the 5.3L V-8 that I bought to pull my 22’ camper. While the Elevation pulled my camper fine it drank the gas like it was on a binge. And with a 26 gallon gas tank it seemed I was filling up every couple of hours. After one trip to Nova Scotia I knew something had to change. I pulled my camper out west to Yellowstone and back through Arizona. It pulled like a champ and fillups were a lot more manageable. Even driving the speed limit out west I still got four to five mpg better than with the gasser. I liked the Elevation but I love the AT4. Way nicer ride and great handling. I get 30 per gallon of diesel on the highway if I drive the speed limit but I got it to tow with. I added a Titian replacement fuel tank so I have 43 gallons instead of the 26 it came with.

Drove about 2 hours one way and it was worth it! Sales guy was very upfront about the vehicle was not pushy about anything and was very knowledgeable about the suv we were test driving to then purchase

I bought this after going to the dealer just to look at colors. I had a 2016 Chevy 1500 LTZ that I loved. There was my down payment and took this Denali home. Only 2 options. Paint and moonroof. I thought my chevy with 3.42 gears was quick. This one goes with 3.23's. The ride is great. Fit and finish are perfect. My only complaint is this Bose/Apple play radio is not what the 2016 Bose was.

Overall I am very happy with my new Truck. GMC however needs to address their software glitch where the display screen intermittently stops working or the audio cuts in and out. I keep hearing a software update is being worked on but that was a while ago?

I have the 1500 double cab with standard bed.
I have the 1500 double cab with standard bed. The reason I have this vehicle is I really like the 6.5 foot bed. The crew cab with same bed is just too long. The things I dislike about this model is that it only comes in the SLE model. For the 2025 that means the external mirrors do NOT have a power fold in and it does not have a seat memory for more that one driver. The power fold in for the mirrors is extremely important to me.

Great service department
I would like to send a big thank you to Ashley Couto for continually providing me with exceptional service. My truck has been in many times over the years for regular maintenance and service and she never disappoints! She takes the time to make sure everything gets fixed and advises me on the unseen issues. She’ll call me and say , we noticed this or that and asks me if I would like to fix it while it’s there and I usually always do! Ashley is one of the reasons why I would definitely keep buying vehicles from them!

Jon A was a gem to work with.
Jon A was a gem to work with. He bent over backwards to find deal/price that suited me. He drove my car home that evening, so I didn’t have to find someone who could meet me at the lot later in the week. He researched and finally bought a charging cord for my new, leased EV (didn’t COME with a cord!! What’s up with that, Kia??). Couldn’t have been nicer and more helpful.

I went in knowing exactly what car I wanted to test drive
I went in knowing exactly what car I wanted to test drive and had an appointment with Jean (John) Venant on December 27th. The car (2024 Mazda CX-5) was waiting for me when we arrived. Our salesman was a great guy & seemed knowledgeable about my particular vehicle. It didn't take me long to decide to buy the car on the spot. Baltimore in the financing department fought very hard to get me the best rate/deal available. They even gave me far more for my trade in that I was anticipating. Everyone throughout the (seemingly painless) process was great to work with. We felt very valued. My only "complaint" is the sticker shock I had when I saw all the "dealer fees" on the bill of sale. Many things (window tint, fabric protector, etc) were all things that you only typically see when buying a brand new car and not when buying a used car. And, with any used car purchase, I made sure to get the extended warranty. That's just smart no matter which dealership you buy from. However, I am concerned a bit to read very mixed reviews of the EasyCare warranty company, as it seems they only approve HALF of the claims submitted. Fingers crossed.

The experience was great at southern Chrysler Dodge Jeep Ram Chesapeake. My salesman, Anton was very up front, honest and easy to talk with. He got the job done in no time! John got my contract together. He too was great to work with. The environment was good. I didn’t feel rushed or pressured and they were very patient with me. I’d definitely go back and recommend others to go as well. Thank you guys for everything!
