Used GMC cars for sale near O Fallon, MO under $20,000

Great truck, solid engine, comfortable, smooth, and it handles great for such a large vehicle. Get one and enjoy miles of roadtrips with all you can tow or haul.

Everyone at the dealership was amazing! They answered all of my questions, made me feel comfortable, and confident with everything! I definitely recommend this dealership to anyone looking for a used or new car.

I love my Acadia Denali. It is fully loaded with anything you can think of.I love the V6 engine and how smooth it drives and rides

Tyreese listened to my wants and even though my initial choice sold prior to my arrival, he found me a better option. He was very knowledgeable about the cars features which made me love my car even more.

I bought this truck new 8 years ago (and 77k miles). I use this truck for truck things like towing a 5,200lb trailer @8 times a year. The V6 has plenty of power and gets good mileage (22 mpg combined, 29 highway empty, 15 pulling the trailer). Reliability has been outstanding. The transmission needs a full flush about every 40k to keep it shifting smoothly. Other than that this truck has been without issue.

Great experience from start to finish. From the salesperson, Ryan, to the finance manager, Curtis, we were listened to and treated graciously and respectfully. We would highly recommend Lou Fusz when looking to buy a new or used vehicle. We love our new car and have peace of mind that our purchase will be protected by their excellent Service Department in the future!

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.....

Blaine was very professional and helped us buy our new car. Thanks, Blaine for everything!

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 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.

After putting off looking for vehicles, as in the past it was usually not a pleasant experience, we stopped at Behlmann GMC. We were fortunate to have been greeted by Doug Johnson. Doug is very knowledgeable and easy to work with. In fact, we ended up buying two vehicles. We recommend anyone thinking about buying to go see Doug.

Have had lots of problems with the wheel sensors. New tires and new sensors and still have the same issue. Shows tire low and it is not. Just car not even two years the air conditioning would not blow out cold air. The compressor in the back went out, need to be replaced. Side car waring lights come on sometimes even though no car anywhere near me. Fold in mirrors are a joke the driver side comes in and out, however the passenger side sticks. Dealer said yeah that happens. This car is garage kept!

I am really grateful for them they really turn my experience around and would come in the near future

I have owned my Terrain for 3 months now, and am absolutely in love with it. Super smooth, great pick up, and I get a lot of complements on both the exterior and interior design. I average 26.3 MPG city and highway combined, which is not bad considering I live in Florida so my AC is never off in the car.

I am visiting in St Louis and needed my 130K service. I called Suntrup West County Volvo and spoke with Greg in Service. When I arrived, he was accurate on him estimated time and came in just under quoted cost. Thank you!

This is my first suv and I was overwhelmed with the style and performance. I have been purchasing General Motor vehicles for a long time. GMC terrain sle is a outstanding investment. I'm enjoying my retirement and my new GMC 👶

Great place to go if you're looking for a no hassle car buying experience. I came here because of the reviews and I left with the vehicle I wanted. Thank you for helping Scott

Bought this 2016 GMC Canyon (4cyl) at car max in 2017 . It was part of a commercial fleet and was well taken care of and low mileage . I’ve only have had one problem and that was in the engine cooling system where I had to replace two hoses and a goose neck . While repairing that I noticed an oil leak around the valve cover so I replaced the gasket . It was under warranty still ( just happened in Jan 2024 ) . I could have repaired it myself but who wants to get all dirty when it can be repaired by GMC at little or no cost to me. It still has 6 months remaining on warranty ( I did purchase from CarMax) hoping it does not need any further repairs . It is 8 years old and according to its records this is the first repair other than natural repair items that had ever been needed . It rides well pulls my utility trailer fully loaded just fine . I also have a 2000 Ranger that I had to replace the tranny on when it was just a few years old . It has never needed any other work. I believe the GMC will last me for years to come . But you never know so I will be buying another after market warranty on it when the time comes . I’ve already added that to a 2015 vehicle I own who’s warranty had expired . I’m a old school mechanic I can repair olde vehicles easily ( compared to todays ) I’m also a former Turbo Prop Mechanic from the Air Force and worked those motors for almost 29 years . I had worked on Piston Air Craft Motors for a few years before the change . A lot like a car piston motor in many ways . Two kinds of piston motors on Air Craft . Line a cars block or a receptacating motor( Round) . Very easy to trouble shoot vs Turbo Prop. Just letting you know that I have experience as a mechanic and know a real problem vehicle when I see one . Would buy a GMC canyon again or maybe go larger due to my new 42 foot long Camper I have rec bought .

Jacob was wonderful to work with during the buying process. I felt like I got the best deal possible and will be returning. Thank you!

Jim and Ken did a fantastic job. They were patient and answered all my questions. They made me feel like the entire dealership was open to me. They introduced me to the service manager. The car is incredible, better than my BMW X5.

I am 84 years of age therefore I have owned several automobiles and cannot compare any other that I have owned to this Acadia. It has been the best overall transportation I have ever owned!

This car is wayyyyyyyyyyyyyyyy better than i thought it would be! It is beautiful, tinted and very comfortable!!! i wont ie i look good riding in my baby

Honestly I am 65 years old bought 40 vehicles in my life it was one of the most pleasurable experiences I'm 65 but 40 vehicles in my life and this was a very straightforward enjoyment in my life to buy a vehicle from them I've ever had with buying a vehicle the people were great honest I don't believe they would rip anybody off and I would highly recommend they have nice vehicles all price ranges I go there first

The styling looks great outside & everything functions as it should. It has loads of options, heated & cooled seats & steering wheel, very cold air, big comfy 7 seats. While not a luxury-looking plush interior, it is very nice. A couple pieces of plastic molding inside are loose, a back panel I tried to take off & the visor mirror on drivers side. I've owned this for 6 months & adore it! Very roomy.

Best salesforce of any dealership that I have ever worked with. They met all my needs and I love my MKZ

Extremely happy. Ride comfort, controls, comfort, looks, quietness, Quality. They should've kept the 2.0 turbo. But this engine not bad at all. Can't wait to get another.

Bought it from my sister. Best vehicle I've owned. Very comfortable and has plenty of power. Love it. It's like anything else you own, regular care & maintenance goes a long way.

I just purchased a 2018 Acadia and I’ve been having oil pan issues. I took it back to open road in New Jersey where I purchased it for a high price repair and am still having issues

I've had mine for 4 years 2016 SLT ,traded my wife's Hyundai Santa Fe for a caddy srx which I drive as well as a 2018 GMC 1500. The Acadia has been super reliable .knock on wood.. just basic maintenance

Really nice to drive! Extremely comfortable almost like a recliner!! Sturdy and solid! GM had issues with certain years for oil consumption is the only issue. I understand GM is making good on it now! As long as it’s checked over otherwise these are extremely nice cars!!

This wasn't the vehicle I'd gone to the lot to see... But it was parked 2 vehicles down, and the price was $3000 cheaper!! It even has more bells and whistles than the Toyota I'd initially planned on getting. Awesomeness!!
