Go see Maurice....he has SUPER POWERS!
If Maurice were a super hero, his super power would be making great deals happen. He was friendly, helpful, informed (and don't even get me started on his accent)! I never once felt pushed or pressured. I am 100% convinced that the great deal I got would not have happened without Maurice. Aside from that, it is a rare salesman who makes you feel like he is really ON YOUR SIDE. I'll keep it short - he's earned my trust and that is the ultimate compliment I can give.
2021 GMC Sierra Denali
This is the nicest truck I have ever owned. Lots of features. Takes a while to learn what all it does but a really enjoyable vehicle.

Palmen GMC/Cadillac- Kenosha, Wisconsin
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.

We purchased a used car from Robert and he was extremely respectful and went out of his way to be helpful. We needed to get a car trailer to get the car back to Louisville Kentucky. He was able to find one and reserve it for us. Everyone at the dealership was very nice and helpful. We enjoyed dealing with everyone. We will always remember the great service and friendly staff. We will remember them if we make any future car purchases.

Oil Change and installing a Rear Park Assist part
I was greeted promptly when I dropped off the car and was given detail on what they were going to do with my vehicle and how long it was going to take. They even offered me a ride home. My vehicle's work was completed 2 hours earlier than expected. Excellent job!

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!

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.

Went in to test drive a Mazda CX 7 and Mourice was the sales associate we worked with. He had the car ready to go for us. He was also very helpful and was the first salesman I have ever liked. He was extremely kind and caring. I would recommend this dealership and Mourice 100%.
