New and used 2025 GMC HUMMER EV SUV SUVs for sale near Round Lake Heights, IL

I have worked with Dan Salisbury for years in regard to leasing various cars. Dan works very hard to find what I am looking for within the payment range I need. Dan never makes me feel bad for additional requests or continued questions. If there are any problems they are quickly resolved. During this last lease I had pleasure of also working with Alfonso Gomez. He was very quick at resolving small issue that I had immediately. Jason Garon in the service department is always amazing about getting my car for any oil changes or needed work. I am happy to recommend this team to others.

Manny and Kevin they did a fantastic job, easy and very professional I recommend them 100%

This dealership is currently getting renovated inside and it’s beautiful! This is also the first time buying a car that I didn’t feel like I was getting “screwed over” somehow. They were very much on our side and enjoyable to work with.

I have visited more than 10 dealerships for my next lease but they are all not supportive. Here at Arlington Heights Buick, I met Shelley Barr and made a deal !! She is well informed and tried helping me a lot. Just try to go and meet her then you will realize it.

They are always kind and great service! They get my car in and out quickly!

The dealership responded quickly via email. Did not end up looking at the vehicle. Appreciate the quick response.

I arrived late to pick up my vehicle. Fortunately one of the Service writers noticed my arrival as he was leaving for the night. He came back to the dealership and secured my vehicle and billing. Great service.

The entire team at this location far exceeded our expectations! Our sales consultant Sandi was extremely easy to work with, and he had our best interest in mind when working on a deal for a new truck. When it came time to financing, Alex ensured we got in and out with exactly what we needed. He provided us personal stories bridging to his recommendations that help guide my wife and I in a direction that surpassed what we originally had in mind. Finally, throughout the visit Edgar and Manny ensured we felt comfortable as we worked though a deal that would ultimately have us driving home without any doubts in a vehicle that can grow with my family. They were the cherry on top to an already excellent experience. Thank you from the bottom of our hearts for such a great team!

Marquartd of Barrington is an amazing dealership because of their integrity and great customer service! I bought my new car 2017 and have relied only on them to maintain it. They are trustworthy and truly care about the customer. Their work ethic and philosophy reflect heavenly standards. I will never go anywhere else!

I haven't had time to get together with the dealership I am hoping to go in this weekend.

Jarvis was an absolute rockstar! He went into all the nitty-gritty details of the numbers, making the daunting task of buying a car a breeze. So happy with my purchase of my Denali 1500, and couldn’t have been as happy without Jarvis’s assistance!

Great service! Mark was awesome. My appointment ended earlier than expected too. Plus a comfortable waiting area with coffee!

Out in 45 minutes. Great clean service center. Service techs, Bob & Jon, are polite and professional. Car was parked right outside the entrance. Thank you for always providing a good experience. Jim Fus

They really made this a smooth experience. Especially when it came to the actual purchase of the vehicle. We dealt with Nick as our sales person and he was great at communicating with us and insuring any needs or concerns were addressed.

I really appreciate the straight-forward buying process I found at Napleton Schaumburg GMC. Thank you to Yiannis for answering all my questions! Best- Mark

Great people. Great service. Highly recommend Erick and team. They will give you a solid deal

I was truly steered by God to this dealership. I am now a customer for life. I found them while searching for a new Hummer ev on the GMC corporate website. I can with great confidence declare that Marquardt GMC and their entire team are truly the pinnacle of what they advertise “Expect, honesty, integrity and transparency.” Frankly, in their quest for professionalism and value for the customer they exceed all expectations. I say this after a lifetime of experience in buying cars as I approach age 70. Please know it’s a smaller, family run type businesses. Note that is has successfully been in business since 1950. That is a testament that they are truly best in class at all that they do. The buying process always seem long, but they go through the effort to make you feel at home, address every concern with care and consideration and make the process comfortable and enjoyable in contrast to the adversarial approach others often take. My wife and I genuinely appreciate the blessings to have found this place, the people, and so happy with our new GMC Hummer Pickup. I can’t speak highly enough about Dave (Sales Mgr) and Tim M, Sales Associate. Thank you very much for the experience, the vehicle and all of the continued support.
