Used GMC Sierra 3500 trucks for sale near Erie, CO under $800,000

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

This review is for a two week old truck. I have been trying to get a 3500HD AT4, gas engine, 8 foot bed, 5th wheel prep, in blue for over a year (almost 2). My dealer finally received an allocation and I was off for the build!! However, when my build order was sent to me the color had defaulted to black (blue was discontinued for 2024) and the only way to change it was to cancel and start over.....so black it is!! The truck is gorgeous and much larger than I thought! I am pleased with both exterior styling and the 2024 interior refesh. My only complaint is the seats, they are a bit firm.....still comfy....but firm. The GM sunroof is small, so small I passed on the option. Mechanically this truck is a pretty sound design. Another 50hp for the 6.6L gas engine would be nice, but 401hp is pretty decent. A PTO offering in the up level trims would be nice, as would a larger/dual fuel tank option is needed (GM is the only one that doesn't offer one), and a factory level in the front, and while I am dreaming a front locking differential. GM could up thier paint game, when approaching 90k I expect better paint. Value wise it is as good if not better than the rest of the over priced trucks on the market. Rumor is 20K per unit on average goes to the UAW pension, that's why your 50k truck costs 70k. In closing I have zero regrets other than the color, but I needed it immediately so here I am.

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!

DJ was my salesman and he did an amazing job! I highly recommend going to Alpine Buick. The Facility is beautifully represented. Always eager to help.

JJ was very helpful and friendly to assist me in my van buying experience. I've never bought a new vehicle in the past so I was lucky to fall into this one in Loveland

Our salesman Eissa Hizhley, was a pleasure working with, he got us exactly what we wanted. Finance Deptment was easy to work with. We will go back again.

Great vehicle for pulling my fifth wheel RV which weighs around 20,000 pounds. This dually truck pulls the RV very nicely without any significant strain on the engine or the transmission. However, like all of today's diesel engines there are 4 different system of emissions on this truck. Each one of these emission systems has sensors associated with them. If one of these sensors goes bad the truck will not perform optimally and sometimes it will go into the limp mode. Unfortunately this is not unique to GMC trucks. All manufacturers are battling this system. Also, I have had to take the truck to the dealer for computer upgrades in order to improve performance. I wish these upgrades could be performed on line (through wifi or with my own phone service). It sure would make things a lot simpler and improve the through put of the dealers who are already strained because of the limited number of available diesel mechanics.

Everyone at this dealership is a class act! Great service. Ask for Ed Rivas to be your lead salesman. He will treat you right and take care of your needs. Extremely knowledgeable and responsive!

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!

It was worth the drive from Silverthorne to remedy a situation with a used Lexus GX460 that I acquired from WCG. The sales personnel were helpful, courteous, and professional and instilled confidence in me to return for future product and to refer anybody to go there for new or used vehicles and service. Ryan in sales and manager Derek got it done promptly which ended up being a faulty tire causing vibration at high speed. Also an honorable mention to Raul! Thank you all. I enjoyed the return drive to Silverthorne.

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

Yamile was knowledgeable, professional, empathetic and a terrific asset for you. She is a keeper!!! I could not be more pleased with the service she provided.

?????????? 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!

Great Trucks! Owned quite a few and they never let me down and seem to hold their value. I will keep buying them for as long as I can.

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

An overall nice truck but for a person at my size(5,11) the mirrors and posts really block the view. My tinted windows really amplify the problem. The hood also takes a bit of room for a short person. Its a comfortable ride and works well in my line of work in excavation. The sound muffler in the hood makes you think something is wrong but apparently its not.

Sales guy was great. Not pushy. Finance guy was quick. Overall experience was painless. Decently fair trade for our 2017 Tahoe. We love our new Tahoe!

Lane Departure saved me on a few long trips. Seats are extremely comfortable. Fifth Wheel Prep made it extremely easy for my hitch installation. Amazing Sound System

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

i did not expect to get the great fuel mileage that i'm getting with this size truck, and the power is fantastic.

Dream truck. I have been wanting this exact truck for a long time. Getting ready to make it my own. I'm done with this review

We purchased our Ford F350 about a month ago for a great price with absolutely no pressure or hassles from anybody there. They took our old F150 in trade and delivered the new truck down to Colorado Springs. Mike replaced the cracked windshield before delivery which we hadn't asked for or expected, which was awesome. Already put a hard 5,000 miles on it pulling a very heavy 5th wheel RV trailor in a across country move. The truck performed great and we absolutely love it!

Best truck I have ever owned. Used to tow a heavy RV. Wonderful comfortable ride. Highly recommended this truck. I drive it as my primary vehicle.

Annissa Medina has helped me so much taken care of everything for me and is always so sweet, understanding, and very helpful with everything that I’ve needed. Her communication skills and personality along with professionalism always reassure me that I am going to get the best service and make me feel like I am always welcomed.

The service was great throughout the process. Essa called me and was there to answer any questions that I had. The process was quick and to the point.

Thanks for the Jeep Rick! And thanks for all the help! The Jeep is really neat, I can finally go rock crawling. Dreams really do come true!

Great vehicle. Plenty room inside and back. Really nice interior exactly what I was looking for. All extras heated seats, Starring whell . Sun roof. Has everything. Ream happy with.

The salesman was very helpful and went out of the way to help me on this deal. I greatly appreciate his help. I would buy another vehicle from this location and not hesitate to recommend people their way. Again I thank Luis and the people at this location. Keep up the good work!

Just what I was looking for and the price was right. The color was the same as the truck I traded in. We have purchased a bumper pull camper and now mountain passes will feel like flat roads!!
