Used GMC Sierra 1500 trucks for sale near Mountainside, NJ

Tito was a very nice sales person. There was no pressure when we changed our minds on which truck to buy. We are very happy with the deal TJ and Tito gave us. We love the truck that we bought!!

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.

Wonderful guys! They were truly there to help and provide a good running and reliable vehicle!!!

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!

Checked out three cars - none of them were “washed just for sale.” Under the hood wasn’t sparkly, but clearly serviced. The trims weren’t stripped-down like elsewhere. And the price - even lower than on marketplaces.

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.

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!

Second vehicle I’ve picked up from this dealership, both times were great. The staff is knowledgeable. The finance process was fast and painless. I’ll keep coming back, and I’ve already told a few friends to stop in!

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.

It mattered to me that no one looked down on me, which often happens - especially if you’re wearing shorts. In summer! But here it felt like a normal conversation. No arrogance, no pressure, almost like you already know each other. That kind of vibe can’t be faked.

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

Buying a truck from a dealership sounded crazy for me, but these guys made it a breeze! Huge shoutout to the guy in finance he was super chill and efficient n sales reps who told me everything about the car so I knew exactly what I was getting. Highly recommend!!

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. ??????????????????????????????????????????? ?????????????

Wonderful customer service. Everyone was very friendly. Listened to what we wanted carefully and helped us get that. Did not try to force us into something else like alot of dealers do. Highly recommend to anyone.

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.

Big thanks to the whole crew! They were real with me from the start, even when I started venting about how crazy prices are these days. I knew my monthly budget was kind of a reach, but they actually made something work. I can’t ask for more!!!

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

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.

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.

I called the service department as soon as my engine light went on. My Service Manager Frank Russo told me to bring it right in. Thankfully I did as one of the cylinders in my engine blew. I had my Jeep returned within 48hrs.

Stefanne Rivera was very professional and worked with me to get my car handed over AAA towing even though I was not able to get to dealer. She understood my condition and was very understanding. She and is a valuable asset to the company.

great night tonight at Performance Buick GMC! Brian Gauthier was super-friendly, informative and made the process as painless and efficient as I have ever seen, and his tag-team partner in finance James Gavenas made the finishing touches of signing the final paperwork simple and fast, while clearly explaining all options and everything I was signing. and they gave me a great deal- Brian on the vehicle and James on the protection.

I purchased a vehicle, a GMC Terrain, from Performance yesterday, July 30th,from this dealership. Alex, Art and Brandon were all professional, courteous and extremely helpful. It was definitely one of my best buying a car experience I have had. Thank you all for the help and effort that was put into the purchase. I live in NY and it was still painless!

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

They found me a Lexus UX with every feature I asked for—big screen, full trim. I had to wait a bit, but they didn’t outsource it from another state. Found it local. Worth the wait—this thing is a beast.

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.

The Crazy Cars team was incredibly honest and maintained all of their promises. I had great faith in choosing them because the whole procedure was smooth, open, and reliable.

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!

The buying experience at Performance was outstanding. Alex Kasper took care of us like family. His knowledge of the product is the best I've seen in any dealership, anywhere. He answered all of our questions and kept us informed about the status of our order at every turn. During the delivery, he took the time to demonstrate every feature of the vehicle, making us confident we could operate all of the amenities that came with the Yukon. Thanks also to Al, who made the financing and ownership paperwork process easy and efficient.

I'm so happy with my 2019 Toyota Highlander and I've been waiting for this moment to have this! They are thorough, trustworthy, friendly, and dependable. It’s obvious they care, not only about the sale, but the customer’s satisfaction before, during, and after the sale.

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
