I was interested in a new GMC Acadia, specific features
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!
Looked at more expensive truck with less options, bought
Looked at more expensive truck with less options, bought the GMC SIERRA AT4 Turbo Diesel 6. I now only put fuel im once a month. And long distance trips are easier due to better fuel economy. One of my best investments ever.

Foundation Cadillac did it again—and honestly, I’m not
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!
2022 GMC Sierra SLT 3.0 Duramax
My 2022 GMC Sierra 3.0 Duramax pickup truck is a good truck. I work on a farm and I also drive an hour to see my girlfriend. For the farm, it has excellent towing capability and for the hour long drive to go see my girlfriend, depending on the weather for traveling, I can get up to 35 miles to the gallon!

Bought a used 2018 F150
Sherry was easy to work with and made buying my truck hassle free. I would recommend this team to anyone.
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.

Surprised myself and bought a GMC
I needed a new pickup and while I wanted a Ford F150 I could not find one set up how I wanted. When I did the Ford dealers didn't want to give what I felt my trade in was worth. I got what I wanted and got a great deal on a 2024 GMC Sierra 1500 Elevation. It is even set up better than the F150's I was looking for and at a better price. I'm very happy with my purchase.

No one likes the process of buying a car, but AutoNation
No one likes the process of buying a car, but AutoNation Southwest actually made it a pleasant experience for me! Sadie and then Lauren were both awesome to work with, professional, knowledgable about the vehicle (Jeep Wrangler Rubicon) that I was looking for, and they were both able to help me, without any bickering and in-fighting like I have seen at other dealerships. Financing was pretty quick, and the dealership was very accommodating about letting me swap Jeep mods out with the new one I purchased. Like they let me switch my after market 37' wheels, so I could have my wheels on my new Jeep. The entire process was as enjoyable as it can be, I felt heard, taken care of and respected. I will 100% buy a car from AutoNation Southwest again. Even if you have had a bad experience at one of the other AutoNation dealerships (I am talking about you, AutoNation West) give ANSW a try, you will not be disappointed. But ask for Sadie or Lauren...they are rockstars!!

Good afternoon everyone, yes, I’m a lady and I’m an owner of a 2017 GMC Sierra 1500 Denali, it has a V8 motor fully loaded sunroof & also it has heated seats & steering wheel for the cold winter months & in those hot summer months you have A/C seats nothing better than that am I correct? It’s been times like that wouldnt trade for the world!! So for all you ladies who think BIG TRUCKS are just for men, go out there & buy one have them put on some electronic slide in/out rails & go out & show the shows the boss!! lol 😄 I’m out looking for a new one now either a 2500/3500 pearl white

Awesome trucks
I've only had this truck for a month and a half and have had no issues. The interior is just plain awesome. I really like the multi function tailgate on this truck, it's very handy loading stuff into the box and the step really helps when you want to climb into the bed. I really like the ride height on the new trucks better than the 2015 Denali I traded in to get this one.

"THE" GMC Truck!
I have a 2023 GMC Sierra 1500 Denali with the 3.0 Diesel engine. I have 20,000 miles on it at the time of writing this. Never owned a diesel before and now i don't think i will own another one without it. I LOVE the engine in this truck. Only complaint would be that it likes DEF fluid while towing so pick up some extra DEF before you head out to tow something. Put about 8K miles on it this summer without adding any DEF fluid. seems to use a little more in the winter or when towing. Very quiet for a deisel and the fuel economy is awesome. Driving 70 mph down the freeway this truck gets about 30mpg, Drive 55mph on regular highways and this truck gets almost 40mpg. All around driving for me is about 26mpg. I used to fill up twice a week with my gas motor and now only once a week. Wireless Apple Carplay works great and the voice texting and mapping is a big plus. I also have the new SuperCruise feature which is awesome. Get on the freeway and set the supercruise on and the truck drives itself until i get to my exit (about 28 miles from home to work). Bose stereo is out of this world and all the storage is great to. I have a swingout bed toolbox, aluminum roll up tonneau cover, Lighted black GMC front emblem, Gloss Black 22" wheels, All Black decals and my dual exhaust bezels are black as well. I rotate the tires and change the oil every 5,000 miles. Couldn't ask for a better truck. Might get the ultimate next time as that has the messaging seats which i kinda wish I had.

I just purchased a Q3 Audi Quattro 2024, very slightly
I just purchased a Q3 Audi Quattro 2024, very slightly used as a loaner, from Derek Fernandez. I have not had a luxury vehicle since the 1990’s, when I had a prized red Audi Quattro . Derek made the purchasing process perfect! Derek’s appearance was professional, down to the business like suit and shined shoes. It is refreshing to meet a young man that knowledgeable about his product and not pushy. He even shared some funny stories while his manager was inspecting my trade in vehicle. The immaculate Audi displayed in the showroom was stunning. Derek’s presentation was seamless. I am prizing the picture he took of me with the big red bow before I drove away. This is so different than the experience I had at Toyota across town, when I was led to a dirty “new” auto on the lot! I definitely would recommend Derek and Audi Denver to anyone! He happened to be a shuttle escort a year ago to a Showhouse I had displayed my Interior Designs in and the ride and escort were the best! I have told everyone at work to shine their shoes and treat everyone like family!

The service performed on my car was perfect. My experience with Clayton was not. When I pulled in he said I'm sending you a text message so you have my number. Feel free to text me with questions. I texted asking for a status update and got no response. After the service I texted asking if he could make a correction to the invoice and their internal system (theyy have an incorrect email address) and got no response. Had I not gone outside to look, I don't know how much time I would have sat there after my car was ready to go. And, they still have an incorrect email for me. Very frustrating experience.

Recently we purchased a Subaru Crosstrek from Flatirons
Recently we purchased a Subaru Crosstrek from Flatirons Subaru in Boulder, Colorado. The dealership was very clean, well organized and made a good impression from the moment we entered it. The available salesman at the time we came in was Connor. He was very polite, professional, knowledgeable and mannered. He showed us several vehicles helping us to decide what to buy. If you want to buy a Subaru I definitely recommend Flatirons Subaru and also ask for Connor. You will not be disappointed. Unfortunately we had the displeasure to run into another person who looked very unprofessional. But the experience we had with Connor, convinced me to give 5 stars to this business.
Overall I am very happy with my new Truck.

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
Pleased that I made this purchase
Waiting for the Refreshed 2022 AT4 was well worth it! With all the manufacturing issues today, building and shipping was slow, but understandable. Love the truck and the features! Fit is perfect and quality is #1. Pricing was too high but all vehicles are running this way. You get what you pay for and this truck is perfect! I have owned many trucks and this by far is the best. The latest features are beyond most other makes and GM has thought this truck through from front to rear.
