Used GMC trucks for sale near Marengo, IA

I had my oil changed with no concerns. Staff was nice.

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 have always taken my cars to McGrath and they have always treated me great , Tyler and the rest of the service department is always friendly and greets you with a smile. They take the time to explain everything and make sure you understand everything,

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.

Josh was super helpful and made the experience very smooth! He answered all of my questions and while I was at Cassill I was confident I was getting a great car at a great deal.

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

Jeremiah was great to work with, we had test drove a car at a different dealer the day prior who just gave us the keys and said see you when you get back. Jeremiah spent time inside the vehicle explaining all the bells and whistles and basic operations, he also went with us on the test drive, a very pleasant experience. The gentleman who went through all of the financing options and the 'sign here' also was informative and kind. All in all a very good experience.

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

They do a wonderful job maintaining my vehicle. Great customer 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

Not sure what to say. I need help getting the truck I like most. Have to see what happens.

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.

Salesman was excellent, finance was excellent. Its hard to complain when you show up at 4:30 the car is little bit dirty and needs fuel. But they handled it all quite well. This was even on a Iowa Hawkeye football weekend! They have some very nice stuff on the lot, and the showroom too!. I loved looking over the selection of Trucks and especially the New Dodge Challengers! No High pressure gimmicks, just honest people making a living doing what they like to do!

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!

Devon Canty was great to work with on an out of state purchase. We got a great car at an amazing price.

I paid over $106,000 for this truck with warranty. Do not care much about miles per gal. at that that price range. Just too much truck for me at my age.

EVERYONE was friendly at Thys Auto. We would go there again just for that reason. They were easy to work with and very accommodating. Small towns are awesome.

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?

Stopped by with a minor problem but major for an old man. Derek fixed the problem for me and had me on my way in a few minutes! Many thanks! James R. DAILY

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!

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.

Brady contacted me right away after building a TRX online. He showed me the Rebel which was also a very nice truck but we put in the order for the TRX! They ended up getting one 6 days later with almost my exact build and he got me in and out of the dealership within a couple hours! The truck is incredibly fast and luxurious, already in love! Thanks again Brady!

2006 Z51 4x4 off road extended cab bought new 8/2005. 139k miles in almost 19 years. Garage kept about 80%. Replaced front wheel bearings and heater core at 50-70k miles. Two sets of tires, one set shocks, one set front & rear brake pads. Oxygen, oil pressure sensors and lower driver seat cover at about 125k. No corrosion in a southern state. Paint and trim almost like new with regular maintenance. Mostly light road use sometimes loaded with heavy cargo and occasionally on terrain at the farm hauling trailers around on dirt trails. Good off road too. Best vehicle I've ever had and will never go out of style. When getting supplies, people at the co-op have asked what year it is and are amazed.

Awesome experience each time. Great team and very helpful. Always looking out and helping with each step of the process. Thanks again for our second new Honda!

2024 GMC sierra 1500 duramax 3.0 is great truck. Great ride and great MPG. 100% recommend to any prospective buyer. Love the truck and how it perform.

My family and I have purchased 9 cars from Four Guys Auto. They have always sold us good quality cars. But, above that they have always been honest and trustworthy. They have gone above and beyond the listed warranty. When purchasing a vehicle, they have always been straight forward about the pros and cons of the vehicle. If they vehicle was expensive to work on, they would tell us. If the vehicle got bad gas mileage, they would tell us. If there was anything wrong the vehicle, they would tell us. Over the years, they have become family. I think that's because they never once tried to "sell" us a car. They are simply good at what they do, and have a passion for what they do. Places like Four Guys Auto are hard to find. Support a local, family owned business.

This truck is everything I wanted! GMC, 4x4, Lifted, Low milage. It's going to be great for my hunting and 4 wheeling! I love it!

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.

I have just started to look for a new vehicle. My experience at Deery Brothers was wonderful. Jordan was very helpful and knowledgeable. I am looking forward to working with him when I am ready to buy.. I will definitely recommend this dealership to my friends and family.

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!

The whole process was great and streamlined for me, love my Jeep and would recommend these guys for any purchase! Whenever I need any maintenance done as well they’re on top of it and get me right in.

Love everything about this Duramax Denali except the fuel mileage. 13-14 Mpg tops when not towing. Bought truck cause previous was stolen. Wish I still had my 6.2 High Country!
