Great Reliability
Great vehicle, 65,000 miles and not a single issue, hoping to get atleast another 100k miles out of it. Extremely reliable. A family member of mine bought a Honda that broke down at 16,000 miles and got stranded. Would absolutely recommend a 2018+ terrain

I LOVE the power
I really enjoy the Terrain. Traded in our beloved Mercedes R350. It was dream to driving on the highway. Our list for new vehicle was easy to get in and out without climbing up or down. No leather seats, hate leather seats, panoramic roof, engine power, get up and go, some luxurious in the vehicle, an easy info console. Before we took a test drive, we did our following tests. How easy to get in and out of the vehicles, leg space (our son is 6'4"). Only wanted two row seating, comfort seating. We checked all other makes. Spend awhile day going from different Dealerships of different makes and models. Didn't want to speak to car salesman, just let us do our preliminary test, on different makes and models. Then we look at the warranties. Finally took take a test drive. Was blown away at the get up and go of the Terrain, pleasantly surprised at the safety features and options it comes with. After almost a month, trips outside the city to the mountains and back. We are really happy with the purchase of the Terrain. Seven years warranty bumper to bumper, ten years on the powertrain. The true fuel economy really surprised me, it doesn't bother me that I have use 91 fuel because of the 2 liter engine. Had to use it on the Mercedes so no change there.

I was truly steered by God to this dealership.
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.

Hector was amazing. He was honest in his review of the car I bought and made sure I was the first to see the car after it came back for detailing. When I left with my new car I noticed the front driver's side light was out, Hector had me bring it in th3 next Saturday and personally made sure it got done. Go to this dealershp and ask for Hector- He's great.

Had a problem with the service department on Saturday
Had a problem with the service department on Saturday when price at payment time was more then discussed. Left dealer pissed off and called when I got home with a cooler head. Nothing was accomplished so I wrote a review that was seen by upper management. Saturday afternoon a gentleman named Mark called to discuss the issue with me. After talking in order to keep me happy and being a returning customer he first had offered his apology for the misunderstanding then refunded the entire service charge price to me. This showed me they're a stand-up dealership. The icing on the cake was the owner Dave called me on Sunday to apologize and assure me he was behind the total refund. Sherman in Skokie a place ypu can feel your needs will be addressed no matter what they are. I will be back in the future. Thanks again Mark and David!
