Dave was fantastic, made the whole process extremely easy. Needed another transit van for our business, they were very knowledgeable and helpful. I have never had an easier car buying experience.

After visiting a different dealership where we felt
After visiting a different dealership where we felt completely overlooked, working with Ali was a breath of fresh air. From the moment we pulled into the lot, Ali greeted us warmly with a smile and a genuine sense of welcome. His approach was never pushy—instead, he was thoughtful, patient, and fully committed to understanding our needs. Ali took the time to truly listen and provided us with a personalized selection of vehicles that matched our preferences and priorities. This saved us an incredible amount of time and helped us focus on what really mattered. He was also impressively organized, having paperwork ready in advance and maintaining excellent communication every step of the way. What stood out most about Ali was not just his knowledge of the vehicles and their features, but the way he worked to ensure we received the best overall value. He proactively reviewed all available incentives and savings opportunities, including several we weren’t even aware existed. He took the initiative to ask meaningful questions, like our professional backgrounds and ownership history, which led to valuable savings we wouldn’t have discovered otherwise. Ali’s service was sincere, thorough, and above all, customer-centered. He made us feel like we had someone in our corner, advocating for us—not just trying to make a sale. That level of care and integrity is rare, and we’re incredibly grateful for it. We wholeheartedly recommend Ali Abdullah to anyone looking for a car buying experience that is honest, efficient, and tailored to your needs. He made a potentially stressful process feel easy.
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!

2019 Sierra SLT X31
I purchased a new 2019 SLT with the X1 package. It has the Red Quartz Tintcoat paint. I usually never leave reviews, but honestly this is the most comfortable, nicest loking truck I've owned , and I've ownwd alot of them. The only issues I've had was the brake software was flawed, took it to the dealer on recall and they installed a new software patch, Other then that I love the styling, performance and the interior is very nice. No regrets

Beautiful Truck
I bought a 2019 GMC Sierra Elevation. I traded in a FULLY loaded 2015 Sierra SLT, that I was really sad to see go, but the Elevation really sold me on styling and ride quality. I lost a couple high end bells and whistles, but the overall performance and look of the truck make up for it big time!

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?

Exactly what I was looking for. Lots of trucks
After extensive searching I found a truck at summit auto center that matched my needs. After deciding to buy the truck, the whole process was actually easier than some local deals I have made. The condition of the truck is outstanding! At 6 years old it is in a condition that one would expect of a 1 to 2 year old unit. I am very pleased with the deal. A search for any trucks I may need in the future will start at Summit Auto Center
Most expensive auto I've ever owned.
Great performance, hard to clean, everything, I expected. Getting lots of compliments and head turning. Stomping with thee BIG DAWGS!!!! Good gas mileage on highway.

Owner of the company reached out to me and take care off all issues even it was after work hours. Good customer service.
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.

Fabulous Exerience
Communicated with John Leno from the Schaumburg facility online. John understood my needs and responded quickly with Jeeps to review - after a bit of humming and hawing on my part, I changed my mind to trucks. I found a truck at another facility, John had it tranferred and within 2 days my soon to be truck arrived - and it is a beauty. John was training Matt and they both demonstrated immense knowledge throughout the interaction and I appreciated the ease of communication (not pushy). I cannot comment on the financing portion of the transaction, but closing went just as smoothly with Hubert and his supervisor. WHile impressed with my transaction I was also impressed with the amount of time that was placed on the training of new employees, or employees transferring. While yes my truck need a repair on the fog lights, it is covered under their warranty, I am highly impressed with my experience. From walking in the front door, to having John take my picture of me and my truck with a giant yellow ribbon... every individual at Carmax truly made the buying and trading experience a wonderful experience. Team Schaumburg, keep up the great work, each of you understand the true meaning of Customer Service, and that is important to some customers like me who still cherish old school values.
Great Buy!
This truck is amazing. Turning heads all over as we tour the area. Those riding with is also enjoy the comforts and safety features. Great Buy!

We had the best experience at the Arnie Bauer dealership! As a first time car buyer, the process can be a little scary and overwhelming. However, Brandon and Alex were amazing. They walked me through every step and were beyond easy to work with. I could not imagine having gone somewhere else. Will definitely only be using them for car purchases in the future!

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.

It was good and prompt.
It was good and prompt. Although it would have been better if there was an adjustment on the tire repair since I spent over $700 a few days ago on 30K mile service plan .
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.

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!

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.
