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

This is a very efficient crew from start to finish! We found a car on line and they met our schedule from start to finish to allow us to find the car of our dreams. Excellent value and we are so glad we found Tiffany, Mark and the entire crew. 100 per cent positive from start to finish. Thank you Dale and Nancy Reisbeck

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

Excellent delivery of my new car. I love their new hybrid. would choose to buy a new car from them again.. the GM Mark was excellent

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 team here went well above the expectations we had. I cannot recommend a better place to get a car! Jimmy and the whole staff were amazing, professional, upfront, courteous and everything you would want and expect from a car dealership and its employees! Top notch for sure!

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.

Lazarus was great to work with and got me a great deal. He was very professional. The people there were friendly. It was a very quick process.

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.

I Didn't end up getting this car. Overall Great customer service and follow through :)

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!

Our two Mazdas were total losses due to the Hailstorm that struck Cheyenne WY on August 1, 2025. I found AutoSearch USA through cars.com and contacted them about a Mazda CX-5 the had listed. Mike Blunn was great! They had just listed the car the previous Friday, and still needed top get some prep work done, but we set up a date to see it the following Tuesday. The car was not quite ready for us to take that day, so we made arrangements to meet at an Enterprise location midway between Cheyenne WY and AutoSeach USA's location so we could finalize the sale and turn in our rental. Everything went off without a hitch. I highly recommended AutoSearch USA for anyone looking for quality car buying experience.

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 !

Sergio was very helpful! Good cars at good prices. Would definitely recommend buying a truck here.

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.

Ricardo was extremely helpful and friendly. Unfortunately we couldn’t find the right car for us.

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.

excellent bought a good car good prices 100% recommended Fatima nuñez the best group 🙏🏻

I truly enjoy every aspect of this vehicle except for the fact that to have my text messages displayed on the screen I have to use a cord and cord my phone into the vehicle. I can Bluetooth phone calls But I cannot get any messages to display without using a cord. For the truck being a 2019 and the price point of it that is absolutely absurd. Other radios that GMCsells has this feature. This truck does not.

Overall we had a great experience at this dealership. Good communication and customer service from Sevan. We believe we found a great car for the price!

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.

Always a pleasure to get my truck serviced at Mike maroone Chevrolet, gmc, Longmont. Joe was my service advisor and got my truck in and serviced a lot faster then i expected. Service was an awesome. Thank yous

It met all of my needs, it drives well and is easy to maneuver for its size. I would recommend this vehicle for anybody who needs a full-size vehicle.

?????????? I had a great car-buying experience at Mike Maroone GMC in Boulder. From start to finish, the team went above and beyond. A special thank you to Austin, the new car sales manager, Brayden, Cosmin, and Alec. Their customer service was outstanding, and what really stood out was their follow-through. Anytime I had multiple questions, they took the time to explain things in a way that I could clearly understand?never rushed, never brushed off. This wasn?t just about buying a vehicle?it was about feeling taken care of. The level of professionalism, patience, and genuine care made this the smoothest and most enjoyable car-buying experience I?ve ever had. I highly recommend Austin, Brayden, Alec and Cosmin, and the entire team at Mike Maroone GMC Boulder!

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...

Thorton Location/ They were undestaffed but did a great job helping all clients did not close until finished. Kelly was our saleman, well knowledged and answered all our questions. David our finance rep did a great job about getting us the best deal. I would refer family and friends.

Great car buying experience will be back for my next one just nice people and nice cars!!!

I was selling my 2017 Forester XT to buy an e-bike to commute with instead and it couldn’t have been an easier process. Shawn came to my home, looked over all the paperwork, took a test drive and wrote me a check. He even allowed me to use the car to deposit the check! What a guy!!! Check cleared no problem and the car was picked up two days later at my convenience. Shawn gave me a price over KBB as well as Carvana and with the difference it paid for my bike along with the Colorado rebate. If you need to sell an extra vehicle Shawn and Custom Cars West is the way to go, no questions asked.

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!

Everyone from the sales rep., sales manager, finance manager and shop team worked to make my experience simple and left a lasting impression. I will absolutely recommend this dealership to anyone in the market for a vehicle.

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.

I recently purchased a truck from SAG Denver, I have had a very positive and professional experience with the sales and service departments. I normally avoid dealerships at all costs, however I came across a beautiful truck that I was having difficulty finding on the private market. I enquired online and was replied to very expediently. I received a no pressure call from a sales person who scheduled an appointment with me. When I arrived, I was greeted and assisted immediately. I test drove the truck with Tracey, who by the way, I highly recommend working with. After driving and inspecting the truck for a bit, I detected what is a common mechanical problem with that type of truck. I brought it up to Tracey and the sales manager Dan and my concerns were immediately acknowledged and validated. Dan did not try to gloss over my concern or argue that there was an issue, instead, he gracefully offered to have the repairs made along with any other contributing or resulting damage as needed. I left the truck with them to begin the repairs, unfortunately it was a bit more involved than originally thought. There ended up being a significant amount of engine work needed, nothing that could have possibly been detectable without opening up the motor. I think most dealerships would have somehow tried to find a way to charge me or unwind the deal rather than proceed with completing all necessary repairs and making the truck run properly. I have several other vehicles so I wasn't by any means inconvenienced, however I did purchase the truck because I had to haul some things for family. After the repairs ran into an extended period of time I did email to express my concerns, I received a call from Dan offering me another truck from their inventory until the repairs were completed on mine. I can't express enough how impressed and pleased I am with the entire experience with Springs Automotive in Denver, I would definitely recommend them and would buy from them again.

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.

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.

Berenyse at the dealership was very helpful and prompt. she helped us throughout the whole car buying experience.

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.

Good responsiveness to customer situation/requirements. Needed information about car capabilities as well as many transaction details that needed to be resolved.
