Great salesman and support staff!
The most important element of this dealership was the salesman. Joe Zielonko was super knowledgeable and a great fellow to work with. In my 6 decades of purchasing cars, Joe is in the top 5 percent. We felt very comfortable with Joe and we did not feel pressured. He listened very well to our needs. He is a credit to the organization.
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!

Best Car Buying Experience EVER
I have bought a lot of vehicles in my life time but this was by far the easiest and most pleasurable car buying experience I have ever had. I sent an email to the dealership around 1:45pm to inquire about a car, drove to the dealership at 5:00pm and drove home at 7:30pm that same day. Ricky in sales was amazing, easy to deal with, I told him what I needed and he took care of it without a bat of an eye!! I will refer anyone to this dealership and specifically to Ricky Pim. Thank you guys!! you are the best! PS - Finance guy, equally as great!! Jersey!
I own a 2023 Sierra 1500 Elevation equipped with the 2.
I own a 2023 Sierra 1500 Elevation equipped with the 2.7L TurboMax, and it’s been outstanding. It currently has 23,000 flawless miles. I’ll admit, I was skeptical of the 2.7 at first, but I jumped in feet-first and have never looked back. Living in Colorado, I regularly tow a 5,000-pound travel trailer through the Rockies with zero performance issues. The truck pulls confidently, handles grades with ease, and still delivers impressive fuel economy—23–24 mpg on the highway and about 18 mpg in town. I couldn’t be happier with this setup. If there is a negative to mention, that would be that after three years of ownership, the black wheels havent grown on me, and Im beginning to hate em. :) Lastly, the mpg while towing drops to 9mpg which is similar to that of a V8. All said, its been a great truck. :)

Was looking to trade in my 2019 Raptor and found an Explorer Tremor. The deal was easy, fast and the salesman was very accommodating and knowledgeable.
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.

After any serving of a vehicle taking it through your car
After any serving of a vehicle taking it through your car wash before returning to customer. This might encourage more customer loyality. Oil change prices are too expensive. The expertise needed to do that job doesn't equalate to charging that amount.

We had the absolute joy of working with T while we bought our vehicle. T went above and beyond in so many ways - by coming in on her day off to help us out, adjusting her schedule to accomodate ours, being open and honest about the vehicle we purchased and the dealership itself - she was able to answer all the questions we had. We even had a small issue (no one could have known at the time of purchase) pop up a week or so after we purchased the vehicle and T was able to get it fixed for us, no problem. And - you know how buying a car usually takes all day? Not here. It took less time than any other place we have bought a vehicle, which is amazing. Thank you, T! You are the best!
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.

Amazing experience .super patient and no hassle team, completely transparent Charles and Rick took good care of us! I would go back there again with my next purchase
Great truck to own.
Great truck to own. The 2023 GMC Sierra Denali with the 6.2L engine delivers excellent power, smooth performance, and a refined driving experience. The ride quality, interior comfort, and overall build quality are outstanding. I have had no issues whatsoever, and it has been a reliable, enjoyable vehicle from day one. I would highly recommend it to anyone looking for a premium full-size truck.

I have had the pleasure of working with Phil Meyer on several car purchases. Phil was very helpful and made each transaction seamless and enjoyable. I highly recommend Phil and Porsche Fort Collins to anyone and look forward to many more years of car purchases with them. The car was perfect!
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.

Great Buying Experience from 1900 Miles Away
Jeff Gipson & his team were a tremendous help in our purchase of a used car for our daughter at CSU. Jeff eased the challenge of buying a car cross country with all his experience in working with parents & students. He was proactive & responsive, identifying a fantastic & safe used car of high quality while staying within our budget, all over the July 4th weekend. The team's coordination of inspecting & servicing the car, processing paperwork, & final delivery of the car minimized the stress of the buying process. We had peace of mind knowing that such an important decision all the way from Connecticut was handled by a knowledgeable, trustworthy team. We highly recommend Jeff Gipson to any student or parent looking for a car.

I would like to share the positive, outstanding
I would like to share the positive, outstanding experience we had with Blake McGuire at Davidson Gebhardt Chevrolet in Loveland. He not only responded promptly to our inquiry in the evening of the availability of the Equinox EV, but, set up an appointment with him the next morning. He is not only is extremely knowledgable about the vehicle, but, was very patient explaining the features of the different models and had us drive the two different models. The entire process from beginning to the final steps of leasing the Equinox EV RS3 vehicle was amazing with all those involved with the deal. Whether you are interested in an EV or other Chevrolet vehicle, we would highly recommend Blake McGuire. It was the best experience we?ve ever had with a dealership.
"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.

Ask for Ray! He's amazing!
After a horrid experience at Greeley Subaru that has us audibly growling at every Subaru we see, we ended up at CarMax Loveland. We both worked with Ray, who is so sweet, chill, and fun to work with. We got my husband set up with a beautiful Kia Soul for the price we wanted. Ray put in for a transfer for the vehicle I wanted and sent my trade in to get appraised. CarMax gave me over $3k more for my car than Greeley Subaru was going to! Ray put up with my impatience over the next few days while my Jeep Renegade was brought up to Loveland (it takes a couple days so they can throughly inspect the vehicles). Ray answered all of my questions timely and professionally. I am telling everyone to go see Ray at CarMax. The business center people were all fun and pleasant to work with and seemed to enjoy working there. This was hands down the easiest, least stressful car buying experience we have ever had.

We have bought 3 cars from andrew and he coworker. These two are the best around. They take good care of their automobile’s and their buyers. We always go to them first and we will for a long while to come.
A lot of truck for the money
This truck is very comfy for long trips. Fits the whole family in. Plenty of extras like the center console charging point. Memory seating helps when you have more than one driver. Very nice ride, drive.
