Great Truck
I paid over $106,000 for this truck with warranty. Do not care much about miles per gal. at that that price range. Just too much truck for me at my age.

I had such a great experience working with Jim Gallegos
I had such a great experience working with Jim Gallegos at Mountain States Toyota! From start to finish, he was professional, friendly, and truly went above and beyond to make the process easy and stress-free. Jim took the time to really listen to what I was looking for, answered all of my questions with patience, and never made me feel pressured. He was knowledgeable about the different options and helped me find exactly what I needed at a fair price. What stood out most was how genuine Jim was—he clearly cares about his customers and makes sure you feel comfortable and confident in your decision. I left the dealership feeling not only excited about my new car but also really appreciative of the excellent service. If you’re in the market for a vehicle, I highly recommend asking for Jim. He made the whole experience enjoyable, and I’ll definitely be coming back to him in the future!

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.

Great working with Zack and the staff Got to drive several trucks till I found the one I wanted. Got a fair trade and a fair price
Great truck!
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!

I always buy here.
I've been living in Castle Rock for 11 years now and found Greenwood Automotive about 8 years ago. I typically changes vehicles every 9-16 months for the simple fact, I like new rides. The crew at Greenwood ALWAYS hooks me up. From taking back my last car to putting me into a new one, the process in literally seamless for me. Over the past 8 years I've purchased and traded in a dozen vehicles without regret. This past week a Mercedes E500 caught my eye and within 2 hours I drove it home, seemless. I literally no longer shop anywhere else. Do yourself a favor, call Steve at Greenwood and treat yourself to a new ride.
Great Truck (sans MPG)
Love everything about this Duramax Denali except the fuel mileage. 13-14 Mpg tops when not towing. Bought truck cause previous was stolen. Wish I still had my 6.2 High Country!

You can trust them!
This dealership took great care of me. Angel Villa was my salesman and got me exactly what I wanted and more. Bought my first brand new car from here and they followed through with everything that was promised from the beginning and somehow still got me a better deal in the end. Dan on the team was also very knowledgeable and even answered the phone when I needed to know what kind of gas to put in the car outside of sales hours. They are just above and beyond!
Failed transmission and full replacement
We have owned our GMC Sierra 1500 for approximately 9 years now. The only real disappointment with the vehicle is that we had to have a full transmission replacement Just after the 100k mile without any warning whatsoever. The truck now has 107k miles on it and now , again out of nowhere, we are experiencing slipping in the trans and the engine light is now flashing. Very disappointing since we are starting to feel uncertain about the reliability of the vehicle now. The truck itself is gorgeous and shows ZERO signs of its age, sporting new rims and tires and a lifted body and no rust on the body at all. We hope there are no major issues with the engine as the vehicle has always been maintained as needed and on time for regular servicing at the dealership.

Five Star Service!
I drove right in, the Service Associate that greeted me was very polite and explained exactly what was going to be done, as I waited for my vehicle he came to check on me and asked if I had any other questions or concerns, it was a great experience and I will certainly be returning to Transwest GMC for all my service needs
This is a great truck.
This is a great truck. It is peppy and well designed. The electronics take some getting used to. The storage inside the tailgate is brilliant. There appears to be a lack of some desired features in the models. Some things should be in the mid range model and they are not. There is no place to mount any radio equipment for GMRS or HAM and there is a lack of 12 volt power sources, Also there is no 4x4 low range in these. I never had to use it much in other 4x4's but it was present, I am not a fan of the online manuals. If you need to look something up, you better have a laptop with you. 2 things concern me; one is YEARLY oil changes the other is the lack of division between models in operations description of features in the manual. There is also a visible seam in the bed were it is welded during manufacturing, Looks like a three year old did it.

Found a desk area with electrical outlet the chairs were kind of old and banged up, and it was kind of in the vending area. Wi-Fi was good for working, but the coffee area was all out of packets for coffee. Good service and they got me out quickly through the process for an oil change the first one on my vehicle and the first service at that location. It was good the The cut customer service was good
2019 Sierra SLT X31
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

Beautiful Truck
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!

Gregory at Castle Chevy GMC is the automotive wizard we
Gregory at Castle Chevy GMC is the automotive wizard we all need! When my wife’s 2023 GMC Yukon XL needed some TLC, Gregory didn’t just fix the issue—he played detective, keeping it an extra day to crack the case like a vehicular Sherlock. And as if that wasn’t enough, he sprinkled some magic dust on a couple of minor, non-essential fixes that were the cherry on top of this service sundae. Professional, communicative, and an absolute delight to work with, Gregory’s the guy who makes you wonder why all car repairs can’t be this fun. Highly recommend him and the Castle Chevy GMC crew for service that’s smoother than a Yukon on cruise control!
Diesel AT4 it!
GMC Diesel Canyon AT4. I've had this truck for a year-11,000 miles. I love it. The Denali and Elevation trim looked like junk. The AT4 can't compete with the Tacoma off road but, It holds it's own off road. The Diesel pulls like a beast and the exhuast brake, on all the moutain passes I drive, is worth it's wieght in Gold. I trailer the max. capacity regularly and it's smooth sailing. I traded in my 2500HD Silverado with the vortec 6.0 for this big, little truck. Best decision I've made in a while. I had this truck on order for 8 months and Gm never accepted the order. I finally found exactly what I ordered, just off the truck that morning that I called. 1300 miles away, I jumped on a plane to go get it. Crying shame GMC discontinued the diesel. The extra $ per gallon right now is easily washed by the increase in mileage, 32+ higway, 19 trallering almost 8000 #'s. I wouldn't want the truck without it. Wouldn't want the Elevation or Denali. Diesel AT4 is the truck. I'll keep it the rest of my life barring accident. I'm sure I can get 40 years out of this truck doing 10-12k a year. The regeneration of the exhaust has never come up but, I only do a little round town driving. Most of my miles are highway and hauling a load. I've heard horror stories about regen. from city folk, commuters... You get what you aim for. If you've given it a lot of thought and the diesel AT4 seems right for you, you won't be disappointed. Good luck finding one. GM - You've a winner here. don't let it get away. Ps. Cars.com doesn't have a choice of how I use this truck for WORK. And wouldn't let me submit this review without selecting one of thier 3 inadequate choices. So, I selected having fun cause I believe everything should be but, this is my WORK TRUCK!

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.

My wife and I purchased a used 2015 Buick Enclave from
My wife and I purchased a used 2015 Buick Enclave from Mike Maroone Cadillac GMC. We live in western Nebraska and saw the vehicle for sale on cars.com. I visited the Mike Maroone Cadillac GMC website directly and found the vehicle on there. There was a wide array of documents related to the vehicle right on the website. I was impressed with the transparency of the information that was offered. I was even able to access the vehicle’s Carfax right on the website. The vehicle was a one owner with a crystal-clear service record that had every single oil change, preventative service, and recall completed on schedule. Negotiations began though a series of phone calls and text messages. Our salesperson, Braden, was very nice and professional, but most of my contact during negotiations was with two of the sales managers, Andrew and Anthony. Both were equally transparent, straight-forward, and most of all very fair to negotiate with. Using only a total loss settlement we received from an accident, we had a limited budget to work with and they really knocked it out of the park! We drove out from Nebraska on Memorial Day weekend to test drive the Enclave and put the finishing touches on the negotiations. Everything went off without a hitch! Even though we paid for the vehicle in full that day, we still had to go through the finance office for all the sale documentation. Eric was fast and friendly, and we were on the road back to Nebraska by mid-day. Unfortunately, on the way home, we discovered an issue with the Enclave’s transmission. We were crushed and started panicking as to what to do. Used cars are sold as is, and we knew that going into the deal. We knew we couldn’t return the Enclave, so we drove it the rest of the way home. Brayden called us on Sunday to ask how we were liking the Enclave. I did not answer and did not return her call until Tuesday morning since it was Memorial Day weekend. I left a message for her explaining the transmission issue and that we were aware that it was sold as is. I then took the Enclave to a transmission shop and had it diagnosed. The Enclave needed a new transmission to the tune of $5,800, plus tax. I received a phone call from the sales manager Anthony and within 5 minutes he offered to pay for HALF of cost to replace the transmission! I sent him a copy of the invoice from the transmission shop, and I had a check in my hand by the end of the week! When I thanked Anthony, he told me, “Doing the right thing isn’t always easy, but we are always going to do the right thing”. Mike Maroone Cadillac GMC earned a life-long customer here and I will make that drive to buy from them again anytime! Thank you, Braden, Andrew, Eric and most of all, Anthony! You are all a class act!

This truck is the truck that all others should look up to. It rides great, will tow a house, runs smooth, and gets great fuel economy. The Allison transmission is so smooth. The AT4 looks great too.

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.
Like the truck but also disappointed
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.
