Used GMC Sierra 1500 trucks for sale near Castle Pines, CO under $899,990

Foundation Cadillac did it again—and honestly, I’m not surprised! When my 12V battery died on my Cadillac Lyriq, David Hann and his incredible team jumped into action. They did whatever it took to get me back on the road quickly and stress-free. David is truly amazing—always professional, caring, and reliable. If you’re ever in need of service, repairs, or even looking to make a purchase, go to Foundation Cadillac and ask for David. You’ll be in great hands!

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 service and always get my truck serviced quickly and get me out on my way! Very friendly and knowledgeable and give me good information on upcoming service needs.

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!

Sherry was easy to work with and made buying my truck hassle free. I would recommend this team to anyone.

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.

Julia Vargas was very helpful and kind as well! She also seemed very knowledgeable and we appreciate her service very much!

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 car at McDonald Hyundai and worked with Sam Soliman. He was both very professional and friendly. He communicated clearly and was efficient in finding a unique financing option that would meet my needs. He was very honest and was able to eliminate much of the anxiety that goes with purchasing a vehicle. I would work with him specifically again for any future vehicle purchases. He made a challenging process move with ease and comfort. Regards, Cecilia Merritts

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.

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!

Great experience Diana helped me out a lot had an easy first time buyer experience drove of with what I wanted thank you Diana and Ethio Motors.

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.

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

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.

Rafael H was very attentive to what we were looking for in a clean used diesel p up . His assistance in our purchase with our purchase was very good . professional, not pushy Gerald & Kay Schreiber

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...

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.

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

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.

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 !

I love this dealership way way underpriced best quality awesome selection even better staff it's funny even the reception is unlike other dealerships the reception is for this dealership actually had car knowledge which was very exciting because if the receptionist knew what was going on with automobiles I could only imagine how great this whole sales team is again thanks for making everything so streamlined

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!

We worked with Leon and Aaron(finance), got what we wanted. They were great! Highly recommend. Thank you!

I needed a new pickup and while I wanted a Ford F150 I could not find one set up how I wanted. When I did the Ford dealers didn't want to give what I felt my trade in was worth. I got what I wanted and got a great deal on a 2024 GMC Sierra 1500 Elevation. It is even set up better than the F150's I was looking for and at a better price. I'm very happy with my purchase.

This was my second time purchasing a car from the dealership and had another great experience. Dan and Frankie were very helpful in picking out a car and were very honest which was important to me. I highly recommend shopping here for a great used vehicle.

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

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

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!

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.

I live in another state and this was my first experience buying a car without driving it first. Very pleased with my car. Thank you Ryan for all your help in making this happen. Service was amazing.

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.

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.

Awesome experience. My husband and I looked at practically every mid size SUV Known to man. Of all the dealerships we visited and all the sales personell we met (including two other far substandard VW dealerships), McDonalds VW ranked #1! The most respectful and helpful sales personell! Tanner and Atticus were both polished, kind, patient, and highly intelligent in their sales positions. I had come to accept that I would have to settle for a VW package that wasn’t quite what I wanted, but Tanner saved the day and delivered (within 24 hours) with my dream car!! Cory (finance manager) worked very hard and truly went above and beyond to earn our business. What an amazing group!! Would highly recommend!!!

I've only had this truck for a month and a half and have had no issues. The interior is just plain awesome. I really like the multi function tailgate on this truck, it's very handy loading stuff into the box and the step really helps when you want to climb into the bed. I really like the ride height on the new trucks better than the 2015 Denali I traded in to get this one.

Tony Rocha is one of the finest and diligent salespersons I have ever worked with. He responded to my Cars.com evening inquiry the very next morning before the dealership was open. Still waiting on other dealerships to respond from a week ago. I purchased a new Z4 M40i and Tony stayed with the transaction until the car was loaded on a carrier. If you go to Schomp BMW be sure to ask for Tony!
