Used GMC Sierra 1500 trucks for sale near Niwot, CO under $1,000,000

I am a college student and not always sure what to do when getting vehicle serviced. The people there explain to me what needs to be done and my options. I have experienced great service at this dealership. The experience here has been much better than I received at other dealerships.

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

We recently purchased a 2023 F-350 from Erin in Loveland. We live in Evergreen [approx 75 miles away], Erin had our deal and all docs ready for us to sign. Felt very comfortable with ClearShift and would definitely recommend to friends and family! Worth the drive for sure!

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 People and love the atmosphere. Very helpful in any questions we had. Definitely would come back for my future car purchases.

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

Thank you Russell King for being professional, and accountable, by standing behind the cars Carmax sold us. Thank you for dealing with our issues in such a professional manner. We are now happy Carmax customers!

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.

We saw the car online a couple days before we could get over for a test drive. We scheduled the drive and the car was ready when we got there. We moved forward with the purchase and were pretty quickly out the door. The car was extremely clean for a 7 year old car, and all the vehicles on the lot looked clean. Friendly sales and finance staff.

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!

I have purchased a number of vehicles from this location under different ownership. The one good constant has been the service department and the service tech Dave Singh. Ask for Dave he will not let you down.

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.

Kelly was awesome to work with. Very friendly and knows how to conduct professional deals while still having a good time. I would definitely buy another car from Kelly,

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!

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.

Amy was fantastic! She contacted me immediately after my asking on cars.com to set up an appointment. And she followed up afterwards. Very nice that Christian (General/Sales Manager) came to say hello.

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.

My experience was great from the time I walked in the door, Luke, Mike, and Kelley were fantastic from showing me what they had in my price range to helping me get approved and out the door with a vehicle. Will recommend them to friends and family 100%

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.

Kerry was awesome and provided me a great purchasing experience. I would definitely recommend this place to anyone who is in the market for a new vehicle.

My husband and I were so overwhelmed with our car search and were worried coming here may be just one more example of the sleazy used car salesman trope--we could not have been more wrong!! Joseph listened attentively to what mattered most to us in functionality, comfort, and price, and helped us to find many options that would be a good fit for us. We had a list of some we were interested in and he recommended some others that would fit the ticket well. He was so patient and informative as we test drove countless cars! Seriously, this guy is like a walking car encyclopedia! But also, isn't afraid to look something up if he's not sure, which rarely happens. It felt like car shopping with your cool uncle who knows everything about cars and is looking out for you. Can't recommend enough asking for Joseph when you need your next car!! He can pull almost any car from another Autonation location, so it's worth going here to work with him even if it's out of your way or doesn't have the car you think you might want! We wound up not finding our vehicle within the Autonation inventory, but still wanted to go out of our way to leave a review for Joseph because he made that much of an impact! A great ally in the stressful, overwhelming process of a big purchase :)

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.

I was in need of a new car . The one i had was bought in 2005 but the year of the car is 2001. I wanted something a bit newer and affordable. I didn't catch the guy's name since my dad was the one who dealt with him first. No pressure at all. He was very helpful. I test drove the car and loved how it drove along with it's a big upgrade to what i had. So decided to buy it. I bought a 2012 Infiniti G25x, leather seats, AWD. front seat heaters, sun roof, backup camera, defrost on the side mirrors and it's a V6. I love it. I highly recommend buying a car here.

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

I have had my 2011 GMC Sierra for a few years now, i love it. i have hauled multiple loads of wood with the truck loaded too the max and a small trailer loaded to the max. can definitely feel the weight but my truck never hesitates at all. Very impressed with the performance of these trucks. i have worked at a ford dealership for years, but ill always drive a GMC.

We have bought 3 cars from andrew and he coworker. These two are the best around. They take good care of their automobile’s and their buyers. We always go to them first and we will for a long while to come.

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.

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. ??????????????????????????????????????????? ?????????????

Came in to Levis auto sales looking for a vehicle, spoke to Levi helped me find my 2010 ford edge fully satisfied, great customer service!! highly recommended!

Looked at more expensive truck with less options, bought the GMC SIERRA AT4 Turbo Diesel 6. I now only put fuel im once a month. And long distance trips are easier due to better fuel economy. One of my best investments ever.

Best experience my family and I have ever had at a used car dealership! Staff is very friendly and attentive. They helped us find the perfect vehicle and provided us with an awesome loan through a credit union. We absolutely love our 2018 Dodge Grand Caravan. We will be back for our next purchase. Thanks Sprinkler!

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

Everyone was kind and helpful during our buying process. Josh in Service has been very attentive and so professional scheduling service dates and getting our missing sensors installed. They all have positive attitudes at all times.

Excellent comfort and very good truck, it is very functional in every way, both for business and for personal, it can be said that I have the 2.7L Turbo engine and I can move up to 11500Lbs already checked by me

Any reviews on this vehicle is not correct. We are first owners and it’s been an excellent truck. We hate to see it go !
