Used GMC cars for sale near Harmony, NJ under $899,990

Couldn't be happier with my purchase from Auto Valley Group. These guys really care about their customers. I looked at few cars and they were all in good condition. Definitely recommend this dealer to others.

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.

Buying process went seamlessly. Test drove one day, ordered one the next. Andrew found what we wanted and we bought it. It was ready in a few days.

The Yukon checked all of my needs, I have plenty of room for my children and my Great Danes. I enjoy driving the Yukon and how it handles, overall love this vehicle!

My wife and I decided I needed a used car December 12th 2019 Sands was the only place we were going but didn't want to share that information when we walked in I guess sometimes you need to keep people guessing. You know my wife and I have bought many new cars and it was the keep you here for 6 hours,disappear with registration,we can't give you numbers unless you commit to buy game. Well completely different was greeted by Greg a salesman ask what I was looking for we told he he graciously walked outside started the car came back in gathered so simple information at this point they had our business didn't show hand just yet Greg stated car was warm we would all take a ride. Closing the deal was actually pretty fast he presented Matt the sales manager paperwork Greg came back and said car is yours ,I mean it wasn't longer then 3-5 minutes from when Matt ran my wife's credit we had decision with amazing intrest rate. We were passed on to Rose a real sweetheart who had the wonderful job of taking care of all the paperwork God Bless Her, we chose to add gap insurance and I think with used cars an extended warranty doesn't hurt either take it from me I always get used the wife gets new lol.Rose spent maybe 30-45 minutes if that and I walked around thanked Matt,and Greg for making this the best experience ever. My only regret is I didn't realize they had 3 lots until the following day with so many used cars I may have bought something different and spent more but I'm happy. To all who helped us have a blessed holiday and my wife and I will be back to trade her car in on a new one.

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!

My daughter saw a car online that she was very interested in so we drove to DND Autogroup from Pennsylvania to check it out. Everyone was very helpful and answered all of my questions with knowledge and professionalism. We decided we would purchase the car but because we were paying cash we needed to return a few days later. Dennis did all of the paperwork for us at our initial visit so that when we came back it was a very quick and easy process. So far my daughter LOVES the car and we are so pleased.

My dad bought the Sierra brand new in 2004 and I recently got it as a hand me down 2nd truck, and all I can say is it's perfect for what I need. Most reliable truck ever and I can get up to 16 in town and 22 on the highway. The 5.3 liter Vortec LM7 is probably the best engine ever made. The transmission is very responsive and the truck is surprisingly quick. And the 4 wheel drive works. My S10 never did that. Would definitely recommend. My only complaint is the ride is quite stiff with the twin leaf spring tow suspension, but it's supposed to be because it's toe suspension.

The sales person Luis was great and very helpful. Went out of his way to get the car delivered to me. He drove it 3.5 hrs so I can have it in time for a road trip. Also they managed to beat the best APR I got from a credit union. All in all it was a professional and positive experience.

Purchased new in October 2024. Total miles driven 9,276. Just completed a 4,734.2 mile trip through 9 states. Just a pleasure to drive. My wife and I were on the road 16 days, with only 8 driving days, longest day was 674 miles. Average driving speed was about 72+ miles per hour. Seat comfort was amazing, no discomfort, great considering having 4 back surgeries. Very solid on the road with little or no driving fatigue. Performance was great. Of the total miles, about 500 were in town driving and 300 miles was in 4x4 in a snow storm coming across Northern Texas in April. Average MPG was 26.4 with my best 500mile drive at 33mpg. The diesel engine is very quiet requiring me to check the tach sometimes to be sure I had pressed the off button. Very quiet on the road as well. This is my first diesel and I would highly recommend it. Plenty of power, great fuel economy, quiet and very responsive when you need that quick acceleration. amazingly nimble for a big SUV. The adaptive cruise works great. My previous GMC was a 2009, 6.2L V8 Yukon XL. I drove that one 140K miles over 14 years with nothing but routine maintenance, a great vehicle as well. Very happy with this 2024

The salesman did a great job and even though I didn't buy the car I was interested in, it was because the salesman had the integrity not to sell it to me as soon as he learned there was a transmission issue with it. The honesty was refreshing.

So far so good! This truck is the nicest truck I have ever driven. The stance, ride comfort and options are top notch. I went from a 2023 High Country that was having drive train issues but had all the creature comforts that you would expect in a top of the line truck. With the lack of confidence in that particular models 10 speed transmission issues, it became necessary to reestablish my confidence in my General Motors product.

Bought a few cars from this dealership. Great customer service and the staff is always friendly.

It is a strong reliable truck and I would likae to have one for myself as a work truck and hauling heavy equipment like a man lift and compressor and still do some light duty work

Couldn’t get the truck Raceway had for sale! So I’m going to find another dealership.

I saw this car driving by the dealership and automatically was drawn to it because of its color. GMC calls it brown but one print out called it crystal metallic purple. It changes colors depending on the weather. I love the handling, the dash and all the bells and whistles! My grandchildren love how much room that it has!

Easiest car buying experience. Wouldn’t dream of going anywhere else. Thanks to everyone involved!

I love my Acadia Denali. It is fully loaded with anything you can think of.I love the V6 engine and how smooth it drives and rides

The team at Star is absolutely amazing! My family has bought multiple cars from them and every time we are treated with the upmost professionalism. The deals are always extremely fair especially with the lifetime warranty that is given.

I love my 2021 GMC Denali 2500HD. I have gotten more complements on this truck than any other vehicle that I have owned. I get great highway fuel milage average 19-26mpg,which is great for a heavy duty truck!

Great Staff and Great Product! Only place I go for sales and service! Highly Recommended!

I paid over $106,000 for this truck with warranty. Do not care much about miles per gal. at that that price range. Just too much truck for me at my age.

Honest and very transparent. Everything was explained in detail and the staff was very friendly. Highly recommend Star for all your truck needs.

One very awesome vehicle. Checks all the boxes you need in a truck and exceeds expectations on quality, performance, and looks great ,too. Love my nre truck.

Had a great experience at Raceway Chevrolet! Working with Anthony, Travis and John was literally amazing. I’ve never had a car deal go so smoothly even with having to change my license from NY to PA. They worked with me every step of the way and got me in my new truck quickly. There was a small issue discovered when I got home and Travis said no problem, we will fix it. Seriously, the best car dealership experience I have ever had!

Have had lots of problems with the wheel sensors. New tires and new sensors and still have the same issue. Shows tire low and it is not. Just car not even two years the air conditioning would not blow out cold air. The compressor in the back went out, need to be replaced. Side car waring lights come on sometimes even though no car anywhere near me. Fold in mirrors are a joke the driver side comes in and out, however the passenger side sticks. Dealer said yeah that happens. This car is garage kept!

I've owned every other American truck and this is my first GMC. I bought the 2500 HD Texas Edition. I absolutely love this truck. It's everything I could have hoped for and more. It is able to pull my 30' travel trailer with no problems. So now when we go out with our trailer I'll have no worries. The look and feel of the truck is outstanding. The 6.6L gas engine actually gets great gas mileage. It gets about the same as my Ford f150 ecoboost. Probably better on the highway. Looking at about 13 miles in the city and 15 plus on the highway. Definitely got a better truck for the price compared to any other american models with the same characteristic and options.

Friendly service; sales staff is superb. I won?t go anywhere else! I never feel pressured or that I?m being taken. The car buying experience is the best!

So far I have been enjoying my 2025 GMC Canyon Denali. It has a great ride and is very comfortable. The Canyon drives very nicely and has plenty of power for my usage (I don't tow anything). It tracks well and has a very smooth ride that rivals previous BMWs (328 and X5's). I have had zero issues but the vehicle is only 1.5 months old (approx 1,700 miles on it). THe only downside (which many people agree on) is that it is seriously lacking storage space. Center console storage is about 1/2 what it was in my 2020 Jeep Wrangler and under seat storage (rear seats) is almost useless ..very little space. That being said, I'd still recommend the GMC Canyon and hope it continues to impress me.

Johnson GMC is amazing from sales to service to finance! Jason and his sales and service team are fantastic, I would absolutely recommend this dealer, you will never go anywhere else!

Bought a demo car . The Acadia has been great . Wife’s car . She likes it . Roomy and good gas mileage . Would also make a great road trip vehicle if I didn’t have a full size Ram .

Star GMC & Tyler S are absolutely the best in the business! Tyler told me the truth about pricing, gave me an amazing deal, so I took an Uber from NJ to pick up my truck. Hands down the best dealership I have ever worked with. You are crazy if you go anywhere else!

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.

Jeff Moran is a true sales consultant professional ! He listens to the buyer to find out their needs and wants. Being an advocate for the consumer is second nature for him. He treats people the way he would want to be treated. I highly recommend any vehicle buyer to reach out to Jeff......you will not be disappointed. :)

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.

I had great experience with Eric Pena at Abeloff Nissan. He did good in getting all the necessary arrangements and document processes done for me to get my Nissan car. I'm excited to buy this car from this dealership with the help of Eric and everyone there. The workers have nice smiles to catch your attention and I love that about them.

GMC Diesel Canyon AT4. I've had this truck for a year-11,000 miles. I love it. The Denali and Elevation trim looked like junk. The AT4 can't compete with the Tacoma off road but, It holds it's own off road. The Diesel pulls like a beast and the exhuast brake, on all the moutain passes I drive, is worth it's wieght in Gold. I trailer the max. capacity regularly and it's smooth sailing. I traded in my 2500HD Silverado with the vortec 6.0 for this big, little truck. Best decision I've made in a while. I had this truck on order for 8 months and Gm never accepted the order. I finally found exactly what I ordered, just off the truck that morning that I called. 1300 miles away, I jumped on a plane to go get it. Crying shame GMC discontinued the diesel. The extra $ per gallon right now is easily washed by the increase in mileage, 32+ higway, 19 trallering almost 8000 #'s. I wouldn't want the truck without it. Wouldn't want the Elevation or Denali. Diesel AT4 is the truck. I'll keep it the rest of my life barring accident. I'm sure I can get 40 years out of this truck doing 10-12k a year. The regeneration of the exhaust has never come up but, I only do a little round town driving. Most of my miles are highway and hauling a load. I've heard horror stories about regen. from city folk, commuters... You get what you aim for. If you've given it a lot of thought and the diesel AT4 seems right for you, you won't be disappointed. Good luck finding one. GM - You've a winner here. don't let it get away. Ps. Cars.com doesn't have a choice of how I use this truck for WORK. And wouldn't let me submit this review without selecting one of thier 3 inadequate choices. So, I selected having fun cause I believe everything should be but, this is my WORK TRUCK!
