I had an amazing car-buying experience at Autoshow! From start to finish, the process was smooth and stress-free. Mike was fantastic—he listened to what I was looking for and helped me find the perfect car without any gimmicks. The man wanted my business. What impressed me most was how straightforward everything was. The team was professional, an efficient. If you’re looking for a hassle-free car-buying experience, I highly recommend checking out Autoshow. I’ll definitely be back!

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

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.

This truck is the base model and that is exactly what we were looking for. A good solid truck without all the fancy technology. It drives like a dream, handles just as well and the interior is sleek and well designed. Perfect black on black exterior.... a man's truck.

"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.

EMPLOYEES REPRESENT THE CORE OF BUSINESS SUCCESS!!
I have purchased or leased three (3) vehicles from Dana. In an industry that is often maligned or misrepresented I had the distinct pleasure od interacting with Mr. John Daly. Mr. Day is a consummate professional with broad and comprehensive knowledge of his profession. I use the word "profession" simply because with representatives like Mr. Daly, the perception and status of the vehicle sales business is raised to the level or a true profession. As an attorney, I interact with people on every level on a daily basis. In the often confusing and even stressful word of vehicle purchase, Mr. Daly exhibited the calm professional knowledge, courtesy and demeanor that made MY purchase a pleasure! Mr. Daly has confirmed my loyalty to Dana as a lifetime customer!! Thank the Dana management and Mr. Daly!!
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. ??????????????????????????????????????????? ?????????????

Pre Owned 2019 CR-V
The best experience I've had when buying a car! Khalil is a wonderful salesperson, he explained everything in great detail for me. I felt no pressure whatsoever and this made me feel more comfortable. If you're looking for a great car and a great salesperson - my advice - go straight to Honda of Hackettstown and ask for Khalil!
best in class
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.

Great deal, they changed the breaks and rotors as promised at the time of purchase, Jessica was completely patient and help us to work on a good deal for us, I definitely recommend this dealership.
Failed transmission and full replacement
We have owned our GMC Sierra 1500 for approximately 9 years now. The only real disappointment with the vehicle is that we had to have a full transmission replacement Just after the 100k mile without any warning whatsoever. The truck now has 107k miles on it and now , again out of nowhere, we are experiencing slipping in the trans and the engine light is now flashing. Very disappointing since we are starting to feel uncertain about the reliability of the vehicle now. The truck itself is gorgeous and shows ZERO signs of its age, sporting new rims and tires and a lifted body and no rust on the body at all. We hope there are no major issues with the engine as the vehicle has always been maintained as needed and on time for regular servicing at the dealership.

Overall I am very happy with my new Truck. GMC however needs to address their software glitch where the display screen intermittently stops working or the audio cuts in and out. I keep hearing a software update is being worked on but that was a while ago?

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. :)
