Used GMC Sierra 1500 trucks for sale near Millerton, NY under $899,990

George and Ethan both were amazing in helping us Trade in our Santa Cruz for a new Sierra Crew Cab Pro.

Great truck, solid engine, comfortable, smooth, and it handles great for such a large vehicle. Get one and enjoy miles of roadtrips with all you can tow or haul.

Thorough and courteous. Great customer service. Oil changed and issue checked out and repaired.

Stong engine and smooth! Highly recommend for familys or someone who likes a smooth truck. Purchased new and have had zero issues since then. Love it!

Had a fantastic experience at blasius, this is my second vehicle I’ve purchased from them. Wayne was so helpful and made the entire process so special and easy for me. The finance manager Marissa was also such a sweetheart and explained everything to me.

I love it the look the interior mine is a red one and it looks so good and it’s my baby and it runs so good and the technology is off the chain

Great service. Great new location. No noisy highway traffic. The 4 lower upholstered 4 chairs were very popular.

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

Am in disbelief every week at the Gas Pumps. Thou a big truck, mileage per gallons are 18 +. Last week it was 22.8. This week 19.78.

Excellent customer service. They made every step of purchasing my vehicle easy and enjoyable. Best car buying experience I’ve ever had. I would highly recommend. I have had my BMW for about three months now and I absolutely love it!

handles and drives great, the electronics don't always work, mirrors don't always work, spray with wd 40, check engine light, EVAP culprit, auto nation has no luck with this, will drive it till the warrenty expires and its back to ford for me

Our sells person Danielle Johnson was very professional and friendly, listened to us in what we where looking for and got us just what we wanted .I would recommend them to anyone looking for a pre-owned vehicle..

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.

A wonderful experience! Nick and Steve were very patient and helpful. I was able to purchase a car with no stress!

Smooth ride strong motor decent gas mileage inside cab is loaded and very tastefully done along w easy access to knobs. Plenty of room. In back seat ! Aclassy looking Truck with a tacky looking owner!!

I bring my fleet vehicle here for repairs/maintenance. Other dealerships have treated me like a second class customer because the fleet company pays for everything. I have never once felt that way at Sullivan's. They are always kind and have gone above and beyond for me at times. My husband became a loyal customer here because of their great customer service.

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.

Purchased a truck from Blasius North last night, January 18. Couldn’t ask for a more congenial group of professionals. They prove doing business can be a pleasure. Special thanks to Steve and TJ. Highly recommend this dealership.

2024 GMC sierra 1500 duramax 3.0 is great truck. Great ride and great MPG. 100% recommend to any prospective buyer. Love the truck and how it perform.

Vinny at Sullivan's Northwest Hills was great to work with and to buy a car from. It was truly a good experience. He was very knowledgeable and let you lead the conversation. I will buy my next vehicle from Vinny the next time I need one.

This truck has a jerk when changing gears sometimes. I enjoy the truck overall easy to handle and comfortable. Drive with ease sight is good when driving.

Worked with Steve, didn't end up buying but he was super nice and upfront with us. A much better experience than some of the dealers we talked to on this journey.

My GMC Sierra is the best ride I have had in all the years that I have been driving. I started driving in 1977. I love my new Sierra.

I became part of the Romeo Buick Chevy family back in October 2015, and since then, I’ve purchased three new vehicles. Each experience was guided by Matt and Steve, who have always been helpful, knowledgeable, and trustworthy. I have great confidence in both the sales and maintenance teams, they truly make this a friendly and welcoming place. I’ll definitely continue to recommend Romeo Buick Chevy to my family and friends!

2021 GMC sierra 1500, 5.3, crew cab 4x4, 21000 miles. brakepad monitor lites up. dealership says needs brakes and rotors in back. one mo. on warranty. our rural roads dirty up the monitor. Needs new monitor. brakes look great to me. No noises. dealer says parts on order GM strike. Can't replace myself cause of computer...

Had a great experience. They were easy to communicate with, I got a great deal and a great vehicle. More than anything, they valued my time and didn’t waste it. Appreciate you guys!

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!

We recently purchased a new and a used cars. The salesman, Pat Duke, was amazing! He was (and has been, with past purchases) a no pressure, and extremely knowledgeable salesman! He handled everything (running support and interference) from the moment we walked into the show room. Pat worked tirelessly both in and on his day off, making calls and texts, making sure that we were attended to and taken care of. Because of Pat Duke, we will continue working with him at Romeo Chevrolet.

The truck has more features than I need. It is quiet and comfortable. it has plenty of power to pull a work trailer. Overall a nice truck

I traded my Chevrolet Silverado for this GM Certified GMC Sierra 1500. It is an attractive and enjoyable vehicle. Some years ago I had a GMC and really prefer them over a Chevrolet. This vehicle is just what I need for hauling and general driving.

My truck has a great appearance, inside and out. It is a pleasure to drive; and rides and performs great. It is the best truck I've ever owned.

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!

This is the nicest truck I have ever owned. Lots of features. Takes a while to learn what all it does but a really enjoyable vehicle.

I've bought 2 cars here and am headed in soon to buy another. THE BEST.

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.
