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.

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.

Best dealership experience ever!
I recently got a 2023 Bolt EUV through Fowler Chevrolet and had the best dealership experience of my life. Great team here, and as an added bonus they aren't adding any MSRP markup like so many of their competitors around town. Last year GM agreed to give me an MSRP swap on my 2021 Chevy Bolt because of the huge delay with the battery recall. I spent several months searching for a dealership to host my swap in both Colorado Springs (where I live) and Denver. I dealt with some really awful dealerships, some very disinterested dealerships, and some dealerships that expressed initial interest but eventually failed to return my phone calls. And then there was the downright shady Foundation Chevrolet (stay far far away from this awful dealership), who agreed to host my MSRP swap early on and placed an order for a Bolt, but then over a month later when they realized they couldn’t slap their $5K markup onto the swap canceled my order out of the blue and set me back almost six weeks as I had to start over from scratch. I contacted almost every Chevy dealership in the Colorado Springs and Denver areas over the following month and wasn’t able to find a single one willing to host. Finally with the help of GM and a district manager I was put in touch with Fowler Chevrolet (I had somehow overlooked them in my search). Their extremely outgoing general manager Nick Guzman agreed to host the swap, and put me in touch with their Internet Sales Manager Doc Holliday. Within 15 minutes of getting on the phone with Doc - who was incredibly helpful and easy to work with - I had a new Bolt order secured, and a promise from Doc that they would not cancel the order on me or sell it to anyone else. The best part was that Fowler had already placed an order for a Bolt in the exact color and trim I wanted that was set to go into production the following month, and they were awesome enough to give me that order (which I’m pretty sure was extra work for them since they would have to swap out allocations with GM) so I didn’t have to wait over six months for a new order. Bolts are in such high demand right now that they easily could have kept that order for themselves and even marked it up $5K. Fowler is clearly more interested in building up a loyal customer base than making a quick buck. True to his word, Doc got me the Bolt I wanted, and contacted me the moment it arrived at the dealership. Doc and Adam Ciotola, their sales turned finance guy, came outside to greet me and my wife the moment we pulled up at the dealership. While Doc took care of documenting my old Bolt for GM, Adam showed us the new Bolt and all the cool features that we didn’t have in our old one. It was refreshing to talk with a Chevy sales rep who actually knew about electric vehicles (which definitely wasn’t the case at any of the previous Chevy dealerships we had worked with), and Adam was every bit as nice and helpful as Doc was. While I can’t speak for everyone at the dealership, I can say that the three people I worked with there (Nick, Doc, and Adam) were all wonderful and made our experience as pleasant as it could possibly be. I would definitely buy a Chevy from these guys again without hesitation, and very well may just make the drive all the way back up there when I’m in the market for another Chevy EV. For now I absolutely love my new Bolt EUV, and if you want a heck of a deal on a great EV and want to buy it from a dealership that actually knows and understands EVs (and customers), give Fowler a call.

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.

Worked with Cosmin on a used Porsche Cayenne.
Worked with Cosmin on a used Porsche Cayenne. Very friendly and professional salesman with a no-xx attitude. Didn't leave me waiting around excessively during price negotiation, and was willing to work with me to find a deal I was happy with. Finance was super quick and low-pressure, I didn't feel like I was being lambasted with upsells that I made clear I didn't want. Good stuff, Austin. Very respectful and professional staff, and I would definitely recommend doing business with these folks. Keep up the good work.

Great luxury ride with great pulling capabilities.
The Texas Edition combined with the X31 package and premium SLT makes a very nice combination. The Sierra 3500HD gives you a luxury interior and ride with all the capabilities of a great pulling truck. The Duramax is quiet yet powerful. It is no doubt the best of trucks for 2020.

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.

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.

Great experience!
Great experience! When I contacted Weld County Garage about a used vehicle, Sales Consultant Miguel Orozco provided exceptional service. Due to my 1.5-hour commute from the WCG location, Miguel provided photos and videos of the vehicle so I could be sure it was worth taking a full day off. I later learned that Miguel had come in on his day off to assist me, a gesture I genuinely appreciate. Having visited numerous dealers in my search, Weld County Garage stood out as the most helpful, professional, and customer-centric. They were not just interested in making a quick sale, but in understanding what I was looking for and finding the right vehicle that fit my needs and those of my family. Unlike many dealerships, WCG encouraged me to take the vehicle to my mechanic for a pre-sale diagnostic check, and all details listed on/about the vehicle were 100% correct. Like many, I have never had a pleasant experience purchasing a used car. However, thanks to Miguel and Craig, the entire process was painless and drama-free, instilling in me a newfound confidence in car buying -- especially with the right dealership staff. Thanks for a great experience, WCG!
