Bought my first car in 12 years and Marco made the experience very smooth. He was great in explaining my options, talking about the various models I was looking at and working with us on finance packages. I had some concerns about a couple tears in the upholstery and Marco was proactive in finding a solution that helped me make my decision. Thanks, Marco!

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.
Overall I am very happy with my new Truck. GMC however needs to address their software glitch where the display screen intermittently stops working or the audio cuts in and out. I keep hearing a software update is being worked on but that was a while ago?

I had an outstanding experience with Bill from Servicing.
I had an outstanding experience with Bill from Servicing. From the moment we started working together, he showed genuine care and patience, taking the time to understand my concerns and guide me through every step. His expertise was clear, but what stood out even more was his willingness to go the extra mile to ensure I felt supported. Thanks to his exceptional customer service, what could have been a stressful situation became incredibly easy and reassuring. Bill truly made a difference.
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!

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

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!

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.

I’d recommend this dealership
Overall we had a great experience at this dealership. Good communication and customer service from Sevan. We believe we found a great car for the price!
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.

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 was selling my 2017 Forester XT to buy an e-bike to commute with instead and it couldn’t have been an easier process. Shawn came to my home, looked over all the paperwork, took a test drive and wrote me a check. He even allowed me to use the car to deposit the check! What a guy!!! Check cleared no problem and the car was picked up two days later at my convenience. Shawn gave me a price over KBB as well as Carvana and with the difference it paid for my bike along with the Colorado rebate. If you need to sell an extra vehicle Shawn and Custom Cars West is the way to go, no questions asked.

My 2016 GMC Sierra 1500 SLT All Terrain - Love it!
I've owned this GMC Sierra 1500 All Terrain since it was 8 months old. With the exception of two warranty issues (failing power brake vacuum pump and transmission electrical harness), I have been totally happy with this truck. Up until now, my 1996 Chevrolet K1500 Silverado with it's 5.7L Vortec engine was my favorite truck of all time, this GMC (5.3L LS engine, 8 speed automatice) has earned the top spot now of my all time favorite truck. It is comfortable to drive, and runs as good as the day I bought it over 5+ years ago. I've got 71.5K miles on it. My biggest issue is I wished it had the 6.2L engine for better towing capabilities. Other than that ... love this truck.

?????????? 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!
Nicest, best performing truck I've ever owned

I love this dealership way way underpriced best quality awesome selection even better staff it's funny even the reception is unlike other dealerships the reception is for this dealership actually had car knowledge which was very exciting because if the receptionist knew what was going on with automobiles I could only imagine how great this whole sales team is again thanks for making everything so streamlined
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.
