We had the absolute joy of working with T while we bought
We had the absolute joy of working with T while we bought our vehicle. T went above and beyond in so many ways - by coming in on her day off to help us out, adjusting her schedule to accomodate ours, being open and honest about the vehicle we purchased and the dealership itself - she was able to answer all the questions we had. We even had a small issue (no one could have known at the time of purchase) pop up a week or so after we purchased the vehicle and T was able to get it fixed for us, no problem. And - you know how buying a car usually takes all day? Not here. It took less time than any other place we have bought a vehicle, which is amazing. Thank you, T! You are the best!

Rafeal was my contact there and he was great. He went above and beyond to communicate share photos and video and was very transparent. As a matter of fact the whole process and everyone was easy to work with. Not the dealer where sale and sale manager go back and forth to do some crazy negotiating. Open transparent and fair dealing. Rafeal was an advocate throughout and in and out with anew car well less than an hr after trade in paperwork

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

Great Service writer.
Great Service writer. Chris was prompt and helpful. I like the attention to the details and listening to all the concerns. Thanks for a great experience.
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.

"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.

Buy your dream ride here!
Great Experience! I personally never heard of this place until I walked in the lot. I found the exact vehicle I have been looking for for years. The place is so unbelievably clean. If you’re looking for a unique ride for your next vehicle start here. Save your time going elsewhere. Gabe and Stefan were absolutely fantastic! I’ll recommend anyone I know to buy their vehicles here.
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. ??????????????????????????????????????????? ?????????????

It was worth the drive from Silverthorne to remedy a situation with a used Lexus GX460 that I acquired from WCG. The sales personnel were helpful, courteous, and professional and instilled confidence in me to return for future product and to refer anybody to go there for new or used vehicles and service. Ryan in sales and manager Derek got it done promptly which ended up being a faulty tire causing vibration at high speed. Also an honorable mention to Raul! Thank you all. I enjoyed the return drive to Silverthorne.
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!

After any serving of a vehicle taking it through your car
After any serving of a vehicle taking it through your car wash before returning to customer. This might encourage more customer loyality. Oil change prices are too expensive. The expertise needed to do that job doesn't equalate to charging that amount.
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!

Hanlon O'Connor Sales Representative
Hanlon O'Connor is above and beyond the most respectful, professional, knowledgeable, and pleasant vehicle sales representative that I have ever done business with. Extremely enjoyable and efficient experience, timely, and honestly fun. Could not recommend him and Christopher Dodge more!!! We walked away with a 2021 Dodge Laramie with a gorgeous night package and I've never been happier with a vehicle purchasing experience.

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.
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.

Straight up
Easiest car deal I have ever done. I have and will recommend them to anyone. I will be back the next time I buy another truck. Thank you guys. It was worth the 2 hour drive.
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.

Helped a friend pick out and buy a truck at Red’s Auto & Truck. We worked with Rick Hawkins and he was refreshingly knowledgeable, professional, and polite.

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

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!

GREAT VALUE - GREAT SERVICE - GREAT TRUCK
HONEST Abe owns and runs this dealership and is not your stereotypical used car guy. He makes promises and keeps them. He took care of the finer elements of a used truck purchase by making sure everything worked and looked good before we took it home. He also referred me to his audio guy and assured that I received excellent service at an excellent price. I got more than a used truck with Truck Kings, I also got access to their network of trusted professionals to modify and maintain it. I will buy my next truck from Abe again.
Most expensive auto I've ever owned.
Great performance, hard to clean, everything, I expected. Getting lots of compliments and head turning. Stomping with thee BIG DAWGS!!!! Good gas mileage on highway.

Best Car Buying Experience EVER
I have bought a lot of vehicles in my life time but this was by far the easiest and most pleasurable car buying experience I have ever had. I sent an email to the dealership around 1:45pm to inquire about a car, drove to the dealership at 5:00pm and drove home at 7:30pm that same day. Ricky in sales was amazing, easy to deal with, I told him what I needed and he took care of it without a bat of an eye!! I will refer anyone to this dealership and specifically to Ricky Pim. Thank you guys!! you are the best! PS - Finance guy, equally as great!! Jersey!
Amazing Truck
Excellent comfort and very good truck, it is very functional in every way, both for business and for personal, it can be said that I have the 2.7L Turbo engine and I can move up to 11500Lbs already checked by me
