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

The Marquardt experience was fantastic. Our sales rep, Fiona, was very knowledgeable and provided world class service. If you are considering a vehicle from this dealership, we highly recommend her.

I have bought high quality two used cars from this dealership and gotten service there as well. The care and time that the entire staff gives to their customers is beyond exceptional. They are always fair and always go above and beyond. (Insider tip: Ask for Mr. James!)

Excellent customer service and great to work with! They even delivered my vehicle to me. Nick in sales is the best from start to finish!

They picked up my car from home and had it back to me so quickly!!!

Thank you so much for a great experience. Chad, the salesman, that I worked with was great. I was a bit nervous before coming in this morning due to my daughter's experience with a salesman at the Kunes next door to this one. But it quickly became a great visit. He was patient and did everything he could so I could drive the car off the lot today. Everyone was very helpful and friendly. He also promised to get me a manual for the Hyundai Tuscon I bought that is missing. I hope he keeps that promise. The salesman, Roel, who was the one next door that my daughter had was not so good. He was demanding and was not very truthful. I believe that he would sell anything or say anything just to make a sale. He demanded that I get in there to cosign for my daughter for a car that was way over her means. Cosigning for someone is a very huge thing and should never be demanded even by a salesman.

Anytime I call and let them know that there’s a problem with my vehicle I bring it in and they take care of it. Found out yesterday that there’s something wrong with my transmission. Thank God for their warranties. I have a special needs son and I need a bigger vehicle and because of them I have that bigger vehicle.

Kim was incredible in helping me get my repairs covered by my extended warranty! Details of service were provided and car was ready when needed.

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!

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

Could not have asked for a better experience. The salesman was very helpful and waked us thru everything in a way we could understand. it was a wonderful experience and would recommend this dealership to anyone looking for a new car.

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.

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

My salesman Esad was great. He was very knowledgeable. Everyone was very friendly and helpful.

Have trusted this dealership for over 25 years. I wouldn’t think of bringing my 2 Buicks anywhere else. They only do necessary repairs which I appreciate and will give you a timeline as to what to expect down the road when it comes to doing work. They value you as a customer and do everything they can to help you in all aspects serving you.

Excellent service Professional service Quick service Polite customer service Excellent customer communication Very detailed repairs

Brought my my car in for normal service and Mark Took care of me. He was great. He pulled up my history on my car and made recommendations for what I needed and explained everything they would do. Also gave me approximate cost of service which was Very close to his quote. Work was done very quickly. Just a great experience. I will be back for my next service when needed. Also everybody that works there were very friendly .

Jim Sprandel sevice mgr. very nice man and also explains everything to you clearly.The rest of the staff was also very pleasant. I would give this dealership 10 stars if I could. My car was washed for me and I needed it considering it was a cold winter day.

Great experience. Tommy was extremely helpful and professional. He kept me very updated and explained everything very well.
