Used GMC Sierra 1500 Denali for sale near Summit, IL

I cannot brag enough about the awesome service received on a recent car repair I have had… Starting with Jackie and all the way through. I was nothing but totally satisfied at how understanding,accommodating ,caring and patient all these employees were. If i could, I would rate these employees and their service 10 stars rather than five… Exceptional service is what I always receive. Thanks Bettenhausen for never disappointing. Always a smooth ride when dealing with Bettenhausen…

Stong engine and smooth! Highly recommend for familys or someone who likes a smooth truck. Purchased new and have had zero issues since then. Love it!

Very quick, good communication . Honest. Feel like you can trust them to be fair. Happy with results. Will return for other needs if they arise in future.

I purchased a new 2019 SLT with the X1 package. It has the Red Quartz Tintcoat paint. I usually never leave reviews, but honestly this is the most comfortable, nicest loking truck I've owned , and I've ownwd alot of them. The only issues I've had was the brake software was flawed, took it to the dealer on recall and they installed a new software patch, Other then that I love the styling, performance and the interior is very nice. No regrets

Very nice place .all people recommend Taras Terry very best dealer.great job for me.i like the dealer

I bought a 2019 GMC Sierra Elevation. I traded in a FULLY loaded 2015 Sierra SLT, that I was really sad to see go, but the Elevation really sold me on styling and ride quality. I lost a couple high end bells and whistles, but the overall performance and look of the truck make up for it big time!

Mario did an awesome job with the customer service and did not feel pushy at all. Mario did everything he could to make a great deal that my wife and I could agree on. Mario and I connected so well that we decided to network after. Awesome customer service and awesome people. Thanks again!

Got the duramax diesel and getting 24 city and 32 highway is very good. Truck drives nice and is very comfortable. My 2 issues with this truck is the backup camera at night is useless (very dark) and interior lighting is not very good. You would have thought a 78k truck would have footwell lights, but it doesn’t.

Very nice dealership, kind courtesy, and knowledgeable people. Fair offers and good inventory, definitely willing to bend over backwards to earn your business. I would recommend.

Am in disbelief every week at the Gas Pumps. Thou a big truck, mileage per gallons are 18 +. Last week it was 22.8. This week 19.78.

Great experience in the service department. Efficient and personable! Communication was on point from start to finish.

Great truck to own. The 2023 GMC Sierra Denali with the 6.2L engine delivers excellent power, smooth performance, and a refined driving experience. The ride quality, interior comfort, and overall build quality are outstanding. I have had no issues whatsoever, and it has been a reliable, enjoyable vehicle from day one. I would highly recommend it to anyone looking for a premium full-size truck.

Zee was great to work with from start to finish. He helped me choose a car the same day. without ever making me feel rushed or pressured. The level of customer service was really good, and I felt supported throughout the entire experience. I truly appreciated how helpful and attentive he was, and I would definitely recommend working with Zee to anyone looking for a smooth and positive car-buying experience.

handles and drives great, the electronics don't always work, mirrors don't always work, spray with wd 40, check engine light, EVAP culprit, auto nation has no luck with this, will drive it till the warrenty expires and its back to ford for me

If you’re not looking to be served champagne and want a simplified buying experience this is the place to go! The no haggle pricing takes some of the anxiety out of the car buying experience, and if you cross check the vehicle on cars.com it will directly tell you if you’re getting a good deal or great deal or fair deal. We purchased a Porsche Cayenne from them and Dan and Brian were awesome! Thank you!!

I have a 2023 GMC Sierra 1500 Denali with the 3.0 Diesel engine. I have 20,000 miles on it at the time of writing this. Never owned a diesel before and now i don't think i will own another one without it. I LOVE the engine in this truck. Only complaint would be that it likes DEF fluid while towing so pick up some extra DEF before you head out to tow something. Put about 8K miles on it this summer without adding any DEF fluid. seems to use a little more in the winter or when towing. Very quiet for a deisel and the fuel economy is awesome. Driving 70 mph down the freeway this truck gets about 30mpg, Drive 55mph on regular highways and this truck gets almost 40mpg. All around driving for me is about 26mpg. I used to fill up twice a week with my gas motor and now only once a week. Wireless Apple Carplay works great and the voice texting and mapping is a big plus. I also have the new SuperCruise feature which is awesome. Get on the freeway and set the supercruise on and the truck drives itself until i get to my exit (about 28 miles from home to work). Bose stereo is out of this world and all the storage is great to. I have a swingout bed toolbox, aluminum roll up tonneau cover, Lighted black GMC front emblem, Gloss Black 22" wheels, All Black decals and my dual exhaust bezels are black as well. I rotate the tires and change the oil every 5,000 miles. Couldn't ask for a better truck. Might get the ultimate next time as that has the messaging seats which i kinda wish I had.

Brian at Marquardt service department was extremely helpful to get my car all ready for winter with a new set of tires. I appreciate having a great dealership near by to handle my car needs.

Great performance, hard to clean, everything, I expected. Getting lots of compliments and head turning. Stomping with thee BIG DAWGS!!!! Good gas mileage on highway.

I've been purchasing automobile from Haggerty in Villa Park for OVER 25 years. Also have them serviced at the Villa Park Haggerty location and body work done at the Glen Ellyn Chevy location. Good people and great service,

I love it the look the interior mine is a red one and it looks so good and it’s my baby and it runs so good and the technology is off the chain

Sold a 2018 Honda Civic 2 dr coupe on Friday, 11/14. Alex was absolutely great. They purchased the automobile for exactly what they had quoted. We will never sell or purchase with any other dealership! They were fair and honest which is not true of many other dealerships. Would recommend whether buying or selling. Do not waste your time with anyone else.

Good afternoon everyone, yes, I’m a lady and I’m an owner of a 2017 GMC Sierra 1500 Denali, it has a V8 motor fully loaded sunroof & also it has heated seats & steering wheel for the cold winter months & in those hot summer months you have A/C seats nothing better than that am I correct? It’s been times like that wouldnt trade for the world!! So for all you ladies who think BIG TRUCKS are just for men, go out there & buy one have them put on some electronic slide in/out rails & go out & show the shows the boss!! lol 😄 I’m out looking for a new one now either a 2500/3500 pearl white

Great Customer Service and dynamic Team when you need professional help any time of the day.

Does anybody else’s truck just sit there after you put it drive? I have to bump the accelerator to have it go into gear. ??????????????????????????????????????????? ?????????????

This truck has a jerk when changing gears sometimes. I enjoy the truck overall easy to handle and comfortable. Drive with ease sight is good when driving.

They were patient to answer all my questions and provided all the answers I needed about transportation of the vehicle to me I would highly recommend them

2021 GMC sierra 1500, 5.3, crew cab 4x4, 21000 miles. brakepad monitor lites up. dealership says needs brakes and rotors in back. one mo. on warranty. our rural roads dirty up the monitor. Needs new monitor. brakes look great to me. No noises. dealer says parts on order GM strike. Can't replace myself cause of computer...

Awesome service from Jose!!! Very patient and kind. Explained every detail. All dealerships need a Jose!

My GMC Sierra is the best ride I have had in all the years that I have been driving. I started driving in 1977. I love my new Sierra.

I just got my Tesla at Affinity. Milton was amazing. He knew exactly what I needed. I strongly suggest that you go see him before EV credit is over.

My truck has a great appearance, inside and out. It is a pleasure to drive; and rides and performs great. It is the best truck I've ever owned.

The staff is very experience and professional. The estimate for repairs were in line with the services. I compliment the facilities with free coffee, water and soft drinks.

I bought this after going to the dealer just to look at colors. I had a 2016 Chevy 1500 LTZ that I loved. There was my down payment and took this Denali home. Only 2 options. Paint and moonroof. I thought my chevy with 3.42 gears was quick. This one goes with 3.23's. The ride is great. Fit and finish are perfect. My only complaint is this Bose/Apple play radio is not what the 2016 Bose was.

Don Hansen best sales person ever. Very nice people. They wash the car, full tank of gas. I test drives the car. The transaction was completed in 90 minutes.

My 2022 GMC Sierra 3.0 Duramax pickup truck is a good truck. I work on a farm and I also drive an hour to see my girlfriend. For the farm, it has excellent towing capability and for the hour long drive to go see my girlfriend, depending on the weather for traveling, I can get up to 35 miles to the gallon!

We received great customer service and were very well looked after. Our vehicle was clean and ready to drive when we collected it. Thanks

I purchased my 2010 Sierra in 20111/2 35,000 miles,l now have 241,000 miles it’s not a work truck other than maintenance repairs it’s been a great truck. I have to say it still runs great,sounds good. I’d buy another one!

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

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.
