Best experience ever in buying a new car best salesmen Ernie and best finance manager Tom They made is so easy and fast and no run around

Our 2021 Terrain SLT is really a nice auto. Gets great 30 MPG approximately, But, 0 to 60 is lacking horsepower. Great Little highway auto. Comfortable.....

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

On my 7th one. That should say it all. Quality crafted, full of great features, super smooth ride and plenty of room for up to 8 people plus a ton of gear.

Terry and the rest of the team were so hopeful. I got my car almost two months ago and very satisfied with it. They mentioned to stay in our budget as well. Very friendly people

I fell in love with my GMC Terrain when I test drove it and have not lost that loving feeling! I have received tons of compliments on it.

Great experience! Minimal hassle with price. The salesman was awesome! The vehicle I bought was in an excellent condition.

Perfect for a couple. Plenty of room and should be good for trips. Room for another couple when going out for fun. Ride is very nice and has a lot of safety features.

So far test drove a Honda and enjoyed it, will come back on Monday to make the deal. They are pleasant to deal with.

I'm 6-4 so I'm looking for a comfortable vehicle that's easy to get in-and-out of plus is high quality. I don't buy new cars and in our 40 years of marriage it's the nicest used car we've purchased.

I have spent my entire life in and around the auto industry and these guys are the only dealer I buy from outside of my own. Dempsey isn't your typical car dealer, and the experience is far more laid back. If you are looking for Unique cars at fair prices, make this place your destination.

One of the most attractive looking t cars GMC has ever designed. Looks just like a Lexus. Extremely roomy. Love every aspect of my Terrain.

Although I didn’t end up making a deal with them, as I am to far upside down in my current car. I will say they were very nice to deal with, salesman I worked with was great, not overly pushy. Overall they were pretty fair and I would recommend them for a new car.

The GMC Terrain is a very dependable auto that I have had no issues. The model is the AT4, which has the headsup display. Interior is nice with leather and all the electronics options.

Very helpful, easy to work k with and prices are just right. I will be buying again.

Saw this car online and knew it was going to be the one. The car is absolutely beautiful inside and out and even better than it looked in the pictures.

The Advisor Tony and mechanic Technician Klaus are the best. I give both of them 10 Stars for such great service. These two both strive to achieve the performance level of Excellence in their jobs everyday. Thank you for such great work

I Love our new GMC Terrain… We had an awesome experience buying our car. The car was better than what I thought it would be!! Inside, It has great space.

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!

Awesome experience. Luigi is a great account manager, walked me through the whole process and it could not of been easier. Once I got to the dealership; literally was sign and I have a new car!!!

Great service and people fast and easy buying process will recommend to other family and friends fun environment and provide coffee and water will be back for all my service needs and repairs

I ordered a 2022 3500 SRW Pro LB Double cab 4x4 in silver metallic / blk cloth. Added preferred package; gooseneck pkg; X31; upgraded wheels; camper/Snowplow prep; black steps. Got the 6.6 gas L8T. No start/stop and runs on all 8 cylinders all the time. I Love this truck. Had Rams and Fords in past. This is my first GM truck. I am in my 50s so not a brand thing... just a great truck. It was delivered in June. Truck rides great, tows very well, reciever or gooseneck. Fuel mileage is outstanding! Especially for a 4x4 one ton. I get 16 to 18 highway when not towing. I was shocked by how well it did and impressed with towing mpg as well. I generally tow between 6 and 14,000 lbs. Loads include a Glacier bay catmaran boat, 30' camper, and 3 axle 25' gooseneck. Truck easily handles those loads. The L8T engine is smooth and powerful. The 6L90 Transmission functions perfectly. If something were to happen to this truck I would not hesitate to order an exact replacement. So far very satisfied. MSRP as ordered was $53,945.

Buying the vehicle was a great experience. Mr. Bob Pearson provided excellent service. He was very responsive, and the negotiation went smoothly. The Financial Manager, Efren Martinez, was also very professional. I recommend the store, and when you're buying a car, look for Mr. Bob. He's sure to get you a good deal.

I love my 2018 GMC Acadia just wished windows were tinted and had a tv for kids and grandkids overall I have had this truck for 2 years and I Love it and use it for family drives cuz of how much room it has I have even used it for work meetings and we all travel to the meeting together .

I had a great experience. I purchased a car at my second visit. On my first visit Luke the manager was very kind. We decided to return because our impression of Luke. Herman was the sales representative. He was very knowledgeable.

I just purchased a 2024 Yukon Denali XL. This is my 3rd Yukon. So needless to say I am sold on this style of vehicle. The style and comfort are impeccable. Had a 2009, 2019 and now a 2024 XL. Never had any problems.

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 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!

Most pleasant waiting room anywhere and the friendliest service people.The mechanics always attempt to fix problems before they start. Also wait time ia always fair.

I love my car. I love the way it handles, and the confidence I have in it when I’m on the road. The room in it is fantastic. All the room I need for when we travel.

I have had this car 5 years 90000 km. No problems so far, it has been exceptionally good. The only money I have spent is gas and oil changes. I. Would buy another one

Phenomenal service and quality car buying experience from start to finish. I was sent to the dealership as a referral and GM Michael Chino reached out to connect with me right away. He was professional and sharp in his engagement. He made sure I was with the right team members and set a time for me to review vehicle options. Jay Hudson and Seth Greene partnered with me at the dealership to learn about Genesis and to find the right vehicle for my family's needs. Jay created an energetic and positive environment and Seth was exemplary in guiding me through the buying process. Each team member did their part and we were able to make a deal that was right for everyone. Quality job by all involved and the dealership itself was well kept and immaculate.

I brought this truck in 2019. I kept taking it back to the dealership to get tweaked several times. Once it was figured out, never got any problems ever again. A little weak on the power side, but, other than that, its a magnificent vehicle. A total work horse. Great on gas. It is totally worth it.
