New and used 2025 GMC HUMMER EV SUV for sale near Algonquin, IL

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.

Kevin Maldonado one of the finest young men we ever dealt with purchasing our 2025 GMC Yukon very knowledgeable friendly even helped us with Sirius Radio, exceeded all expectations! Thank you once again G & L

Fast professional easy to work with didn't feel pressured this is my 2nd purchase from them I will definitely go back when it's time for another purchase.

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!

Thank you to the service team for your getting me all set for my roadtrip!

Super honest deal. Used car as advertised, no surprises, no pressure. They detailed it for us while we did the paperwork.

From originally purchasing my car at Haggerty to having my car serviced at Haggerty, my experiences have all been positive. Everyone is friendly and answers all of my questions. Work is done well and on time.

I have brought my vehicle in for every oil change I have needed. Always courteous and professional, my car gets a diagnostic check every time and is freshly washed. I like that the Service Department send out coupons, and making an appointment is easy online or with a phone call.

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

Great customer service, was wonderful working with Jessica and Moe. I will be back again.

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!

Always great service at Arlington Heights GMC. Mark Lubrano is wonderful to work with. He always gives you special attention to make sure all your service needs are met.

Manny was extremely helpful and knowledgeable in helping purchase a new Terrain. He made the experience painless and was always looking out for what was best for the buyer. A+

Frank was friendly and helpful. He look up my records to make sure I was not receiving and paying for unnecessary service. He provided a coupon.

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.
