2024 GMC 3500HD AT4
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.

I just wanted to thank Rob for getting me out of a difficult jamb. My battery was failing, which required multiple jumps, and Rob was able to get me into service immediately even though his schedule was quite full. Rob had the battery replaced within 30 minutes of my arrival. I have never visited Fowler dealership in the past but will make it my go to place for future services.

Great customer service on top as soon as I get in..was greeted with attention forced on me.also car was clean and showed me all the services I records.
Truck is a Solid vehicle overall.
Has a really Big feel to it. I currently use mine to pull gooseneck trailer. I haven't had a load yet that I couldn't pull. The downsides to this truck is to me I feel it could get better fuel mileage. Also I had trouble with #4 injector...dealership replaced it. Now my AC doesn't work all the time. Although it sounds like it's blowing it isn't.

Great dealership!
Great dealership! Great communication, easy to set up an appointment with, kind and knowledgeable staff. We worked with Tyler Donnellan and could not recommend him more! He was very transparent, kind, answered all of our questions thoughtfully and got us out of there within 2 hours. Andy was the finance manager we worked with and we also couldn’t recommend him more. He presented all the information clearly and made us feel comfortable. I would definitely come back when the opportunity arises. Thank you all! 🙏🏻🧿😊🚗

Great Diesel truck when emission sensors work
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.

Sales and finance teams were extremely flexible and
Sales and finance teams were extremely flexible and attentive, listening to my concerns and working to find solutions. They supported 2 different test drives when I had a concern about a specific driving condition, being extremely flexible working around my schedule. Cam, Austin, and Alec worked together to provide answers to all of my questions regarding financing and extended warranties. When a last minute issue arose on a Friday afternoon, their maintenance department obtained the part and swapped it out on a Saturday morning to allow me to pickup the car that afternoon. Communication was excellent, receiving 2 status updates that morning.
Love my GMC HD
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 was interested in a new GMC Acadia, specific features and model. Zac Taylor worked very hard to bring a vehicle from the Colorado Springs store. He had everything outfitted as needed, worked out details remotely, then delivered it to me in the mountains. I drove away a great new vehicle at an outstanding price point. Thank you Zac for all of your hard work during this car purchase!

?????????? I had a great car-buying experience at Mike
?????????? 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!

Super Satisfied
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.

An overall nice truck but for a person at my size(5,11)
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.

GREAT VALUE - GREAT SERVICE - GREAT TRUCK
HONEST Abe owns and runs this dealership and is not your stereotypical used car guy. He makes promises and keeps them. He took care of the finer elements of a used truck purchase by making sure everything worked and looked good before we took it home. He also referred me to his audio guy and assured that I received excellent service at an excellent price. I got more than a used truck with Truck Kings, I also got access to their network of trusted professionals to modify and maintain it. I will buy my next truck from Abe again.
