Used GMC cars for sale near East Chicago, IN under $899,990

Sam and Scott were able to help me with a service issue. A pleasure and timely assistance.

I bought my 2020 with 36k miles a couple of years ago and I now have 60k miles of trouble free very enjoyable driving. It was expensive, but worth every penny. The ride is so quiet and comfortable my wife and I prefer traveling in it instead of our 2018 Acura MDX which we also love. The 5.3 V8 has plenty of power and towing ability. The multi-function tail gate is genius, I hope to never be without one again. We so enjoy all the bells and whistles, especially the wireless phone charger. So glad I bought this truck!

I had a very enjoyable experience. Brad Siemsen greeted me in a friendly manner. Then, thank you to Kevin Dralle for making the the rest of my visit go very smoothly. He was concerned that I understood the process of having my vehicle appraised and presented me with a fair offer, which I accepted. He assured me that he would be there in the future for any further questions or concerns I may have. Thank you!

Overall I am very happy with my new Truck. GMC however needs to address their software glitch where the display screen intermittently stops working or the audio cuts in and out. I keep hearing a software update is being worked on but that was a while ago?

Ashley did an excellent job presenting the vehicle and making sure we understood all the many options.

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

Kevin and supporting cast were very responsive and good at communication. We traveled 2.5 hours to buy a car As Described from them.

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.

Working with Castle Jeep was simply awesome. I have never had a better experience at a dealership. Josh and Tony did such a great job working with me. I don’t have enough good things to say about them.

I've owned this GMC Sierra 1500 All Terrain since it was 8 months old. With the exception of two warranty issues (failing power brake vacuum pump and transmission electrical harness), I have been totally happy with this truck. Up until now, my 1996 Chevrolet K1500 Silverado with it's 5.7L Vortec engine was my favorite truck of all time, this GMC (5.3L LS engine, 8 speed automatice) has earned the top spot now of my all time favorite truck. It is comfortable to drive, and runs as good as the day I bought it over 5+ years ago. I've got 71.5K miles on it. My biggest issue is I wished it had the 6.2L engine for better towing capabilities. Other than that ... love this truck.

I could not get a decent car any were CarMax put me back into the drivers seat i will recommend CarMax to anyone Andrea and his team in Tinley Park are truly number one in car sales . Marcel Potvin.

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!

Hands down, one of the best dealerships in Northwest Indiana. Very professional to the customer. The staff is amazing.

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!

It was a very smooth experience, Nick Marzullo was extremely helpful - even off of the clock!

Waiting for the Refreshed 2022 AT4 was well worth it! With all the manufacturing issues today, building and shipping was slow, but understandable. Love the truck and the features! Fit is perfect and quality is #1. Pricing was too high but all vehicles are running this way. You get what you pay for and this truck is perfect! I have owned many trucks and this by far is the best. The latest features are beyond most other makes and GM has thought this truck through from front to rear.

Great experience at Muller Acura of Merrillville! Juele went above and beyond answering the questions I had about a CPO vehicle they had for sale. I was 50 miles away in IL, so we couldn't easily pop in to check it out. We were very sensitive to things like ex-smoker vehicles, and Juele went out to the vehicle, running the A/C, and looking for stains. I could hear the car running in the background as she checked (and it was not a smokers vehicle). Then when I was able to come into the dealership on the weekend, it was pulled into a bay inside since it was threatening rain that morning. I was able to take all the time I needed to inspect and test drive the vehicle. When it came to negotiating the deal, there was some back and forth on price and trade that was very amicable, and they were very willing to send me detailed OTD price before I drove out there. We ironed out the remaining details when I was there, without a lot of the normal "salesmanship/posturing" most dealers do. And all along the way, Juele and their team were calling out any "gotchas" that may come up with an IL person buying from IN dealer, which was very appreciated. The rest of the tean there, from the finance manager to other sales people, were very friendly and no nonsense. For any future friends and family, I'd steer them to this team for their next purchases in a heartbeat.

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.

I recommend this place to my friends and family. Bought my stepdaughter a car from here. Fair $$. Good car

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!

Cheyenne Fontanez is the best! This process started back in March of 2025 when I was gone for the winter and she stayed in contact with me until we got a deal done on 10/8! It was a seamless process and I couldn’t be happier!

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.

Excellent customer service, Andy was one of the best sales guys I’ve ever worked with. Knowledgeable, listened to my needs, and helped me get the perfect car. Couldn’t recommend him enough.

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

I had one of the best experiences with this dealership, I recommend it 100% . I drove one hour and half , but it’s was worth the trip

Everything I want in a vehicle. I love the interior and the slick look of the overall vehicle itself. Oh can’t forget about all the different options Available on this truck. It has so much to offer!

There are some dealerships and then there is Betthenhausen Fiat! Great folks that made the process so simple!

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...

Zee handled my application and provided an excellent level of service from start to finish. He explained everything clearly, step by step, making sure I understood each part of the process. His patience and professionalism made the experience smooth and stress-free. Overall, I received great customer service and truly appreciate the support.

This truck is the base model and that is exactly what we were looking for. A good solid truck without all the fancy technology. It drives like a dream, handles just as well and the interior is sleek and well designed. Perfect black on black exterior.... a man's truck.

Process was incredibly simple and Blayne (salesman) and the finance group were awesome. I was coming from out of state and they were able to accommodate me and I drove my truck home within 45 minutes of getting there. I can’t recommend them enough!

Most seamless purchase EVER. Adam Rausei is competent and decent, as is manager Matt Monix. You won't regret working with them!

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

Smooth ride strong motor decent gas mileage inside cab is loaded and very tastefully done along w easy access to knobs. Plenty of room. In back seat ! Aclassy looking Truck with a tacky looking owner!!

I purchased pre-owned 2020 1500 SLT in February of this year. The truck rides comfortable and has plenty of room front and rear. My and I both enjoy it. My only drawback is the turn radius (lock to lock). It lacks compared to my wife's 2018 Yukon SLT, or the 2016 Ram I traded in. Have to many times maneuver twice to park it going forward or reverse. Otherwise happy with our purchase.

Great experience. The sales, finance team, and owner were great to work with. Fast and transparent closing. Much better the. The last car buying experience I had. Glad we made the 4hr drive. I would purchase from them again.

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!
