Absolutely the most easiest trade and buying experience
Absolutely the most easiest trade and buying experience ever. I was dreading buying a new car but Jason squared everything away and made it the best experience. Thank you so much for helping us out!
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 recently bought my teen's first car from this
I recently bought my teen's first car from this dealership, and I had such a positive experience! I was looking for an affordable price point with the best mileage and reliability for a young driver. Brandon and Leon were incredibly helpful, patient, and transparent throughout the entire process. As a woman, buying a car at a dealership can sometimes feel intimidating, but I never felt rushed or pushed. They made everything easy and straightforward. I truly felt like they had my back, and most importantly—my teen ended up with the perfect car for what I was looking for. Highly recommend working with them if you're looking for honesty, kindness, and a smooth buying experience!
This truck has a jerk when changing gears sometimes.

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!

Great Car Dealership!!!
My daughter and I had a great experience at Schomp Mazda. We were provided great customer service and were thoroughly satisfied with our purchase. We arrived at the shop closer to closing and was able to secure a vehicle within that time. I highly recommend this establishment to anyone in the market for a car. Thanks Avery and Stephen!

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

Ashley is the best! She is a great listener and responds with empathy and kindness. She is professional and genuinely caring. This was the best car buying experience I have ever had. Thank you Ashley!
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.

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!

Great Experience
I did my research and found a great deal at Denver Auto on a Subaru Forester. The car was ready and waiting for my scheduled test drive. Right by the door. They let my mechanic look it over. It had just had lots of repairs/maintenance. My mechanic verified all this. Stan was great and I purchased the car!! Still going strong!! Thanks Denver Auto!!!
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
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

Will Buy Again.
I bought a Chrysler 300 from levis. A couple years ago. Customer service was great.I compared pricing to other dealerships and the price was on point. The were very transparent on pricing even showing a price comparison of other competitors. Also ,They threw in some custom rims 22in and a second set of when for $500. Car was in sound mechanical condition. Never had a problem with it. Will definitely be buying again.
Great Truck
I did my research and test drove several models. The GMC 1500 Duramax does everything I want it to do and more. Great gas milage, nice power and very comfortable.

Surprised myself and bought a GMC
I needed a new pickup and while I wanted a Ford F150 I could not find one set up how I wanted. When I did the Ford dealers didn't want to give what I felt my trade in was worth. I got what I wanted and got a great deal on a 2024 GMC Sierra 1500 Elevation. It is even set up better than the F150's I was looking for and at a better price. I'm very happy with my purchase.

Great sales
Everything went smoothly my sales agent was the best showed me everything I needed to know about my 2023 Ford Ranger. I would highly recommend them.
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.
