Used GMC Sierra 3500 trucks for sale near Gleneagle, CO

My entire experience at this dealership was extremely positive! The sales staff was very friendly and helpful. The store manager was very much involved in a positive way. I am very comfortable with having purchased a 2020 Tacoma there.

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.

I have regularly maintained my 2003 Dodge Durango SLT at this dealership since it's original warranty period expired. I like the service team's general approach to maintenance (which has not changed under different ownership) - address only mechanical issues requiring attention at the appropriate time and accomplishing identified work with sound credentials. No repairs have ever been performed that required a call-back. I think I generally take very good care of this vehicle and I believe its underlying engineering was solid to begin with, so, all around, it's been a good partnership over the years.

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.

Savanah was AWESOME!!!! Great disposition, friendly, very informative, professional. (and my grandson, Ashton, fell in love with her... he's 5) My ex-husband has done business with Phil Long twice in the past and recommended them to me. I actually let him come along LOL....

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.

Carrie Baker was very professional and courteous! Every time I took my truck in I knew she was going to make sure it was done right and she does that to all her customers!

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.

The customer service at Carmax is excellent. This is by far the best car buying experience I've ever had. They were super friendly and did not waste a lot of my time. They were extremely efficient throughout the entire process.

I love the new features this truck offers. I would highly recommend this truck if your looking for a Diesel. I provides all the features and benefits you would want.

Recently purchased a vehicle, and was pleased with customer service and straight forward pricing discussions. Our sales consultant, Starlynn and sales manager Tyler were great to work with. Thank you for such a positive experience.

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.

Very helpful staff, great vehicles. Very patient with us. Fair trade in value given to us

I brought my car in for service and Lee in service was absolutely exceptional and made it totally awesome and wonderful experience. He went above and beyond to do everything he could to make it that way. He is a total asset to the company and I am very grateful and will be back definitely.

Exceptional Service. Great Price, Professional. Delighted Customer. Outstanding service Department. Sales and Financial members were upfront and professional. Looking forward to being a customer for life.

I really appreciated the free service for my first time in with our new car.

Comfort, ease of driving, style, convenient for work and we LOVE the tailgate! Great for towing our heavy fifth wheel and our dogs are riding in style!!

AJ Al-Amin was a wonderful salesperson. Friendly, knowledgeable, patient, and kind. He help me find the perfect new car!

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.

Very friendly sales staff, concerned with our needs and wants. Low pressure and provided info on all the cars we had interest in.

The truck met all my expectations and more so far. the engine is powerful and the ride is smooth. the interior is great and so are the things this truck has.

I bought a Jeep Wrangler for my son last week and as I drove it off the lot I discovered the radio didn't work. I thought, "Oh shoot, I just signed an 'As is - Where is, No Warranty'" document. I brought it back to Jamie, their used car manager, and he immediately smiled and said, "No problem." He had a brand new radio installed and didn't charge me a dime. Who does that?! Jamie does. When it comes time to hang up the spurs on my own Ford F-150 you can be sure I am heading back to Phil Long Ford. They are people of character and integrity.

Naythin, the salesman was very helpful and was able to get me all of the information that I needed to help make a decision.

Always get great service. Staff is very friendly, helpful and knowledgeable. Would highly recommend the dealership to anyone.

This vehicle fits all my needs. Powerful enough to pull my 32 ft travel trailer - excellent powerful engine and engine brakes kicking in on downhill slopes

Keri is OUTSTANDING. Listens to my requests, provides me with options, and then enacts my decisions. Does not change the plan without getting my approval first.

My experience with Castlerock Chevrolet since 2020 one of the best. I appreciate their customer satisfaction. Puts their customers first. My car engine almost destroyed by an oil change of a place I used to get by cheaper but no more. Thank u again.

Nicest truck I have ever owned preforms great with my RV Truck is comfortable and still works great when you need it to preform. Ride is nice and very roomy for all that want to travel with me
