2022 GMC Sierra SLT 3.0 Duramax
My 2022 GMC Sierra 3.0 Duramax pickup truck is a good truck. I work on a farm and I also drive an hour to see my girlfriend. For the farm, it has excellent towing capability and for the hour long drive to go see my girlfriend, depending on the weather for traveling, I can get up to 35 miles to the gallon!

Everyone there from reception to sales and finance were
Everyone there from reception to sales and finance were so welcoming and helpful. Seong was the kindest and patient through every part of the process. He was accommodating with my circumstances and made sure that I walked out of there happy. I then got to meet Kevin from finance. He was super kind and made sure I had everything I needed before I walked out of the building. I can't recommend this team enough. I love my Bronco!

Robert and Nathan, the two automobile salesman, were great. They were helpful, patient, and nice.
Like the truck but also disappointed
Got the duramax diesel and getting 24 city and 32 highway is very good. Truck drives nice and is very comfortable. My 2 issues with this truck is the backup camera at night is useless (very dark) and interior lighting is not very good. You would have thought a 78k truck would have footwell lights, but it doesn’t.

Only dealt with them via text. Very responsive to our needs. Decided not to buy anything at this time.
Pleased that I made this purchase
Waiting for the Refreshed 2022 AT4 was well worth it! With all the manufacturing issues today, building and shipping was slow, but understandable. Love the truck and the features! Fit is perfect and quality is #1. Pricing was too high but all vehicles are running this way. You get what you pay for and this truck is perfect! I have owned many trucks and this by far is the best. The latest features are beyond most other makes and GM has thought this truck through from front to rear.

This was an online purchase with salesman Roq Micheal’s. He was very helpful and made this online deal flawless. Reached a purchase price with Jonathan and felt confident to put down a $1000 over the phone. We had already did test drives in Chattanooga TN. ALM couldn’t even be beat even by Marshall Mize Ford. Great job ROQ.
Looked at more expensive truck with less options, bought
Looked at more expensive truck with less options, bought the GMC SIERRA AT4 Turbo Diesel 6. I now only put fuel im once a month. And long distance trips are easier due to better fuel economy. One of my best investments ever.

Just a GREAT experience from beginning to end!!!!
Today was the day to pick up my car! A week ago, after just a day of discussions, Sammy and Aaron made what had been a terrible mistake I had made a couple of months ago into a WONDERFUL sales experience! And THIS during a pandemic when I was having to try and correct my mistake while sheltering in place at home. You see, I have always driven foreign vehicles and SUV's since 1999. And there have been a lot of them, just never an American car, except for my play Jeep. But, our family needed a larger vehicle and we had decided on a Navigator. In January, we went large and purchased a Navigator. Unfortunately, we didn't go large ENOUGH... We needed a Navigator L to accomplish our needs. You can imagine the pain of this realization given the depreciation that takes place the moment you drive a car off the lot. AND I didn't figure it out for over a month. Well, I had spent almost 2 weeks negotiating with the dealer I had purchased my previous vehicle from as well as EVERY OTHER Lincoln dealer in the Metro-ATL area...All not willing to help me with my problem and at the end of the day leaving me to feel as I was going to have to live with my mistake. Then Sammy called ME! And within one day we had worked out a deal for a trade that I could very definitely live with. In fact, one that I could even be excited about. And the pricing for my trade (granted it was almost new) was done site unseen. AND when I got to the dealer there was NONE of the haggling or you didn't tell us about this, etc. Just fair-mindedness, and during these dangerous times...A SAFE environment! I couldn't have asked for more. And when they needed to do some work (tinting, clear-bra, etc.) work to my new vehicle, I was immediately placed in a wonderful loaner until my new vehicle was ready. SO MUCH Better than my last experience. These guys are doing it right and have earned by service business. Yes, It's a long review, but these guys deserve it. I look forward to meeting my service adviser and working with these guys for years to come! AND I can't wait try the Pick-up and Delivery Service!!!!!
Nicest, best performing truck I've ever owned
My truck has a great appearance, inside and out. It is a pleasure to drive; and rides and performs great. It is the best truck I've ever owned.

Great Service from Sales Crew
The Motorpoint sales crew was very courteous and Rossy B. was very knowledgeable about the Tesla I was interested in. This was one of many things which made me very comfortable with my purchase along with a follow-up call to make sure everything was fine with my new purchase. Rossy answered all of my questions, including the ones I didn't know to ask. Top notch service which gives me the confidence to recommend them to friends as well as furture purchases for me and my family.

I came from Columbia SC to look at a Jeep Sahara I saw online. Greg greeted us at the door and got us into a test drive and then purchasing the vehicle without any issues. He was friendly, efficient, and made my car buying experience a breeze. I would recommend ALM Marietta to friends and family, and ask for Greg!!!
Surprised myself and bought a GMC
I needed a new pickup and while I wanted a Ford F150 I could not find one set up how I wanted. When I did the Ford dealers didn't want to give what I felt my trade in was worth. I got what I wanted and got a great deal on a 2024 GMC Sierra 1500 Elevation. It is even set up better than the F150's I was looking for and at a better price. I'm very happy with my purchase.

I will begin the 5-star review by naming all the wonderful people we have worked with at this relaxed yet professional Delarahip: Fabian 🤩 Robert aka “Bob” 😎 Will and Dylan 👍 👍 It’s not common for me to say, “I just don’t know where to begin…” when it comes to excellent customer service, professionalism and patience. This team is well informed, willing to help, did I mention patient?! We all know how it can be when you go to a Dealership…salesman can be pushy because the product is likely subpar. Well, that wasn’t our experience AT ALL. They made us feel like they truly wanted to find out our needs so they knew the best way to accommodate our family. They Delivered!!! Additionally, when you purchase a brand new car with all these amazing features, it’s not uncommon for it to have some hiccups as you get used to the systems. Well, we didn’t have to work through the hiccups alone. “Bob” 😃 along with an amazing service tech, FaceTimed me…yes he FaceTimed us in order to be able to walk my husband and I through our CarPlay mistake (my words NOT his of course. It was our mistake) 😉. Additionally, Fabian is a chill, yet extremely professional guy and we LOVE working with him as well. He listened to our concerns, determined the best way to approach and he executed … He Delivered! Thank you Fabian for being amazing. Dylan and Will, our very first point of contact. Great listeners. Patient. Eager to please. We thank you Hendrick Family. The Kitchens Family.
Great truck!
I bought my 2020 with 36k miles a couple of years ago and I now have 60k miles of trouble free very enjoyable driving. It was expensive, but worth every penny. The ride is so quiet and comfortable my wife and I prefer traveling in it instead of our 2018 Acura MDX which we also love. The 5.3 V8 has plenty of power and towing ability. The multi-function tail gate is genius, I hope to never be without one again. We so enjoy all the bells and whistles, especially the wireless phone charger. So glad I bought this truck!

My salesman, Dave, was outstanding from the very beginning of the contact and sale. I believed he was honest and represented the company well. He and I agreed on a price over the phone, and I accepted it. Before the purchase was completed, I was engaged by another dealer with a lower price. However, I chose to stay with Dave because of his integrity and my belief that a deal is a deal.
"THE" GMC Truck!
I have a 2023 GMC Sierra 1500 Denali with the 3.0 Diesel engine. I have 20,000 miles on it at the time of writing this. Never owned a diesel before and now i don't think i will own another one without it. I LOVE the engine in this truck. Only complaint would be that it likes DEF fluid while towing so pick up some extra DEF before you head out to tow something. Put about 8K miles on it this summer without adding any DEF fluid. seems to use a little more in the winter or when towing. Very quiet for a deisel and the fuel economy is awesome. Driving 70 mph down the freeway this truck gets about 30mpg, Drive 55mph on regular highways and this truck gets almost 40mpg. All around driving for me is about 26mpg. I used to fill up twice a week with my gas motor and now only once a week. Wireless Apple Carplay works great and the voice texting and mapping is a big plus. I also have the new SuperCruise feature which is awesome. Get on the freeway and set the supercruise on and the truck drives itself until i get to my exit (about 28 miles from home to work). Bose stereo is out of this world and all the storage is great to. I have a swingout bed toolbox, aluminum roll up tonneau cover, Lighted black GMC front emblem, Gloss Black 22" wheels, All Black decals and my dual exhaust bezels are black as well. I rotate the tires and change the oil every 5,000 miles. Couldn't ask for a better truck. Might get the ultimate next time as that has the messaging seats which i kinda wish I had.

Awesome trucks
I've only had this truck for a month and a half and have had no issues. The interior is just plain awesome. I really like the multi function tailgate on this truck, it's very handy loading stuff into the box and the step really helps when you want to climb into the bed. I really like the ride height on the new trucks better than the 2015 Denali I traded in to get this one.

Short turn radius
I purchased pre-owned 2020 1500 SLT in February of this year. The truck rides comfortable and has plenty of room front and rear. My and I both enjoy it. My only drawback is the turn radius (lock to lock). It lacks compared to my wife's 2018 Yukon SLT, or the 2016 Ram I traded in. Have to many times maneuver twice to park it going forward or reverse. Otherwise happy with our purchase.

Friendly and helpful salesperson. Knowledgeable about the different vehicles I looked at. Finance person was quick easy to discuss details. I had an issue with the earnest money and they refunded the amount in one day. Very pleased with the service and would choose them again.
Great Truck
I did my research and test drove several models. The GMC 1500 Duramax does everything I want it to do and more. Great gas milage, nice power and very comfortable.
