Best Car Buying Experience Ever
I had the best car buying experience ever! Jacob was amazing from the time I called and spoke to him on the phone and met him in person. He found the perfect car for me! The finance department got the loan done quickly and was very straightforward and kind. In conclusion, Everyone was friendly, had my best interest in mind, and was very professional. I literally was in and out. Easy peezy!

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!

I am very impressed with the used car team at Gebhardt.
I am very impressed with the used car team at Gebhardt. Kris was very knowledgable and friendly, responding to all my weird questions. Ryan managed to find me a better interest rate than my own bank. Tom gave me a bit of history of the dealership - one of the few remaining family-owned dealerships in Colorado- and showed me his beautiful classic car. I’ll be a customer for life!

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?

All in all I would buy another car here. Our only complaint is even though we bought the car thru their website and did everything including trading in, it still took us 3 hours to sign all the paperwork and for them to evaluate our trade in. T

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.

Great dealership!
Great dealership! Great communication, easy to set up an appointment with, kind and knowledgeable staff. We worked with Tyler Donnellan and could not recommend him more! He was very transparent, kind, answered all of our questions thoughtfully and got us out of there within 2 hours. Andy was the finance manager we worked with and we also couldn’t recommend him more. He presented all the information clearly and made us feel comfortable. I would definitely come back when the opportunity arises. Thank you all! 🙏🏻🧿😊🚗

Oryn Orozco has been extremely helpful, knowledgeable, professional and very patient. He has been wonderful to work with and has found me the perfect RAV4 XSE hybrid. Can’t wait for it to arrive!
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.

This review s for James Wells.
This review s for James Wells. I had been looking for the car I wanted at three dealers Longmont and Golden and Flatirons and James was the only salesman the came out in the car lot and sold me a car. He was great , always called back, always very nice. James was great , the dealership was great. Everything went smooth! Thanks Henry Glover
I have the 1500 double cab with standard bed.
I have the 1500 double cab with standard bed. The reason I have this vehicle is I really like the 6.5 foot bed. The crew cab with same bed is just too long. The things I dislike about this model is that it only comes in the SLE model. For the 2025 that means the external mirrors do NOT have a power fold in and it does not have a seat memory for more that one driver. The power fold in for the mirrors is extremely important to me.

I dealt personally w Manny Rodriguez. He was intelligent, knowledgeable, honest and transparent. I applaud MM Chevy for hiring such an inspiring young man. Would go back again in a heartbeat!! I purchased a nice Silverado due to Mannys professionalism! Phil Bravo
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.

"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.

What a great way to buy a car! AutoSearch will give you unbiased advice on any make or model, then decide on what you want and let their staff do all the work to find a car and bring it to you. And the best part is the deal will be quick and simple with no added pressure.
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

We saw the car online a couple days before we could get over for a test drive. We scheduled the drive and the car was ready when we got there. We moved forward with the purchase and were pretty quickly out the door. The car was extremely clean for a 7 year old car, and all the vehicles on the lot looked clean. Friendly sales and finance staff.
Just wondering
Does anybody else’s truck just sit there after you put it drive? I have to bump the accelerator to have it go into gear. ??????????????????????????????????????????? ?????????????

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!
