I worked with Seth Caldiero and he helped to make buying experience very seamless and a low pressure event.
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!

Service was as expected. The rep was friendly and kept me informed regarding the progress of my service. I am very pleased. Thanks
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.

Working with Berenisse in the purchase of the car I was wanting was an awesome and pleasurable experience. She was not only very knowledgeable but a treat to communicate with and made the whole experience wonderful. If you are looking to purchase a vehicle from Sharpest Rides I recommend working with her hands down. It was my pleasure to work with her.

This truck is the base model and that is exactly what we were looking for. A good solid truck without all the fancy technology. It drives like a dream, handles just as well and the interior is sleek and well designed. Perfect black on black exterior.... a man's truck.

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.

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

Austin Ellenberg helped us find the exact Buick Enclave
Austin Ellenberg helped us find the exact Buick Enclave that we wanted. He was very nice to work with and patiently helped us understand all the new features on the 2025 car. His explanations of everything were excellent, and we appreciate his offer to talk with us again about any new questions that we come up with. We also appreciate that he had a new battery installed before we took possession of the car, since the previous extreme cold temperatures had run down the battery while the car was on the lot.
I have enjoyed my vehicle.

3 years with a loaded 2021Yukon Denali deisel
I own a 2021 Yukon Denali with 23K. At nearly $90k, I purchased every option except for the silly entertainment screens fastened to the back of the front seat headrests. (nice for leaving the imprint of your passenger's faces on the screen in an accident - buy a couple of iPads. First of all, kudos to GM engineers. Technology actually exceeds German cars I've owned. Rear view camera is GREAT and adjustable for brightness, distance and width. But, make sure you purchase the washer for the rear lens...Miirror is almost unusable in rain..(blurring with rain and dirt quickly. I'm 6'2" and really ticked-off there isn't a handle on the "A" pillar to grab to pull into the driver's seat. They put a handle at the upper center of the door opening. What is that for? I have to grab the steering wheel (fortunately rigid with the engine off). Another big problem is the loss of both knees in a frontal accident. With the steering wheel all the way back, I can't even come close to stretching my leg out. Really! A couple of bigger issues: I know the front of this vehicle is right off of the truck, but the end result of the gigantic, unsloped hood, is the inability to see anything 12 feet in front of you. And making right turns.....better memorize that curb before you start your right turn because you won't see it again. Just "that look " from your wife as you run over the curb again with your right rear wheel. Lastly, I hope someone from GM reads this.....With all the awesome high-tech items on this car, why are there no "turn" lights? You know, the lights that let you see where you're going, especially right turns. Porsche has LED lights designated for turns that light up the whole area you're turning into. In the Yukon at least I'll see what I ran over with the terrific rear view mirror! My only intermittent mechanical annoyance is when I push the door handle to lock the doors. It's supposed to fold the mirrors in which is a good way to check you locked the vehicle. occasionally , they don't fold and I have to push the button 4 times. Of course, the mechanic needs only to push the button till it works and tell me it's working. Twice. Guess they win. I'll live with it. Now for the rest: Fantastic overall vehicle! With the air suspension it rides better than Mercedes or Lexus. I always get positive remarks from passengers. The steering wheel control for the Active Cruise control is absolutely perfect. I've driven between Arizona and Colorado without taking my hands off the wheel (just moving my thumb). And the engine, I LOVE THE INLINE 3.0 DIESEL! Almost got the 6 liter but took a chance on the diesel that just came out (in 2021). Same exact torque as the V8 and great for passing. The big difference ..... I had to take a photo of my dash to prove to my friends....heading back to Phoenix with 256 miles on the odometer averaging 30.2 mpg going the speed limit! My Porsche Cayenne gets 19.6mpg (not going the speed limit). The 9 cameras help when parking unless your wife is with you. When I come to a stop I'm waiting for my wife to hold up the 1 to 10 signs like the judges in the olympics. And lastly, For a car that will raise 5" in 4 low, why does the car come with 1 ply polyester sidewalls ? I'm not comfortable on gravel or rocky roads for fear of a sidewall puncture. I highly recommend this vehicle. The designers did a great job making this big vehicle look sleek and smaller than it is. I'm a bit unnerved when I see a vehicle like mine come flying into a parking spot for a perfect 4-point landing and the driver is a 110 lb soccer mom. And I just spent 20 minutes with a micrometer adjusting my position so I don't get "that look" again from my wife. Good luck and hope it's reliable.

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!

Recently purchased a new Tucson hybrid from Schomp
Recently purchased a new Tucson hybrid from Schomp Hyundai. Everyone at the dealership was very friendly and helpful. After our purchase we set up an appointment with Jazz, the product specialist, to go over the features and operation of the new vehicle. New vehicles are getting more sophisticated and also more complicated to understand all the features. It was great to have a knowledgeable person to go over the features and settings. In addition, she helped us with connecting our phones and what features were available through the smartphone connection.
Yukon Denali all new styling and pleasure to drive
Nice styling,interior has a new design dash which is beautiful and convenient,safety features and cameras are great and easy to used and the active cruise is awesome.

Shopping at Auto Nation Suburu in Golden was a pleasure. I used to dread going to a dealership. Not this time! There was no high pressure, just a willingness to answer all of our questions. The salesman, Eric, was patient with us, and we are both senior citizens, unfamiliar with all the new technology. By showing and demonstrating all the many safety features, we were convinced to buy our new Ascent. Dick and Phyllis Moore
Buy one if you can afford it
Excellent and reliable, only thing buyers have to do is buy a AFM disabler that you can stick into OBD2 port to avoid lifter failure (longer story, nobody wants a V8 to run in V4)

"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.

My wonderful car buying experience
I was very pleased with the vehicle I was able to purchase at Grand Valley Auto Lakewood! I had less than perfect credit after being left carless in my divorce. My friends had recently purchased a car from Mike and Kelley and they assured me I would be treated honestly and fairly. I was very skeptical due to the fact that I had recently been taken advantage of on the purchase of my new TV. They listened to my wants and needs and I left in a car that I both loved and knew would do the job. I would definitely recommend and return for my next vehicle purchase!
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. ??????????????????????????????????????????? ?????????????
