I purchased my vehicle through Sill-Terhar Lincoln -
I purchased my vehicle through Sill-Terhar Lincoln - Broomfield CO and had an amazing experience working with Anthony and Kelly. This was my first time purchasing a vehicle out of state which was very nerve wracking. Anthony was my eyes and ears throughout the entire process. He was sending me videos of the vehicle and keeping me up to date on the big things. Kelly was absolutely wonderful. With a two-hour time difference, he was still answering my calls and/or text immediately every step of the way! They are a phenomenal team and were a pleasure to do business with. The paperwork and transportation were seamless, and they held my hand throughout the entire process. Huge Thank you to them!
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!

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

Chris at Interstate Ford was absolutely amazing. He searched his inventory for a vehicle that I could afford. I would shop there again!
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!

Charlie was absolutely fantastic. He was extremely knowledgeable and was able to answer all my questions. The process was quick and easy. I couldn't have asked for a better experience.
Short turn radius
I purchased pre-owned 2020 1500 SLT in February of this year. The truck rides comfortable and has plenty of room front and rear. My and I both enjoy it. My only drawback is the turn radius (lock to lock). It lacks compared to my wife's 2018 Yukon SLT, or the 2016 Ram I traded in. Have to many times maneuver twice to park it going forward or reverse. Otherwise happy with our purchase.

Overall customer relationship skills were excellent. I Bought a used car that was not ready to go when I flew in to pick it up because of a poor inspection. They worked hard get it right. But, it took awhile.
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!

?????????? I had a great car-buying experience at Mike
?????????? I had a great car-buying experience at Mike Maroone GMC in Boulder. From start to finish, the team went above and beyond. A special thank you to Austin, the new car sales manager, Brayden, Cosmin, and Alec. Their customer service was outstanding, and what really stood out was their follow-through. Anytime I had multiple questions, they took the time to explain things in a way that I could clearly understand?never rushed, never brushed off. This wasn?t just about buying a vehicle?it was about feeling taken care of. The level of professionalism, patience, and genuine care made this the smoothest and most enjoyable car-buying experience I?ve ever had. I highly recommend Austin, Brayden, Alec and Cosmin, and the entire team at Mike Maroone GMC Boulder!
Better than my old truck
The truck has more features than I need. It is quiet and comfortable. it has plenty of power to pull a work trailer. Overall a nice 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.

Initially I dealt with Dan, the owner, over the internet. Then I dealt with Steve at Castle Rock, then Martin at Parker. They were kind, caring, and helpful. Honestly, Dan may be the best communicator I've ever dealt with. He always responded immediately, I was mostly impressed with his immediate and accurate responses. I bought a 2017 F350 and I feel I got a great deal and was well taken care of. Thank you Berkenkotter Motors Tomm Olsen Michigan

overall i like the truck alot, its a very dependable vehicle. it has its little quirks for a used truck. there's little things like the drivers door switch for the mirrors and the door locks that are not working as of now but i haven't taken the time to look into it as of yet. minor to me and i'm sure i can fix for a few bucks. nice riding and driving truck i would buy again.

Cyia was extremely helpful and pleasant. I ended up buying elsewhere at a dealership that was closer to me. It is not a reflection of anything the dealer did or didn't do. I spoke with Cyia and thanked him. He was very accepting and cordial.
