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.

I am writing to say that I appreciated so much the helpful and friendly Jon Roman at NuCar Lowell. I am always looking to note wonderful service and high integrity from sale people. I leased a Chevy Equinox on Saturday, Feb 8. When I picked up the car I had a lot of questions and needed assistance. Jon was wonderful, and I wanted to be sure to thank and assure him that I will be recommending him when asked. "where should I go to buy/lease, who would you recommend?" 5 Stars for my buddy Jon!
Perfect for us!
As we age, our reaction time may become slower. This vehicle is loaded with features that make me a safer driver. It connects wirelessly with my iPhone for hands-free Apple CarPlay. Love that! And the Acadia is a dream to drive. It’s the perfect size for me and my family

I always bought the GMC Acadia (4 times) but decided to try the terrain. I absolutely love it and it's a great car for zipping around in town. I would take it for a weekend trip but not on a long trip as it doesn't have a lot of cab room, but for two people it is fine

Awesome Experience!
One of the best experiences we have ever had! We have been looking for a truck with a plow for months. Found Auto Mart when they popped up on Facebook Marketplace. Best find ever! Dealt with Peter on the phone. Very helpful every time we called him, and very patient because it was our first time buying online. This includes him meeting with us on his day off and not rushing us one bit. The price was good and we feel him and Chris took very good care of us. We will go back, and highly recommend them.
The best deal 4me my dream truck it's mine if poss
I want this truck if I can't get help with finances I'll try againfri and ill have cash. I want it 100percent I've only dreamed of owning a truck like this and now if the Good Lord willing and the creek don't rise.a dream might come true.,!!!!!! I love everything about this ride.just rite for the open road.

I purchased my 2016 GMC Terrain SLT in 2018 as a gently used vehicle with only 21,000 miles on it. I never had issues with it. I kept it regularly serviced and had to replace tires. At now over 93,000 it has been a comfortable and very reliable car. The only feature I wished it had was rear air conditioning. Living here in the SE it gets hot and it takes a “minute” to get the back of the vehicle cooled down. However, I rarely have back seat passengers, and thankfully, the really hot weather lasts only a few months! I have been very pleased with this car and would recommend it to others. I traded it in a week ago for a larger car only because I need the room for a grandchild, and my elderly parents.

My 2016 GMC Sierra 1500 SLT All Terrain - Love it!
I've owned this GMC Sierra 1500 All Terrain since it was 8 months old. With the exception of two warranty issues (failing power brake vacuum pump and transmission electrical harness), I have been totally happy with this truck. Up until now, my 1996 Chevrolet K1500 Silverado with it's 5.7L Vortec engine was my favorite truck of all time, this GMC (5.3L LS engine, 8 speed automatice) has earned the top spot now of my all time favorite truck. It is comfortable to drive, and runs as good as the day I bought it over 5+ years ago. I've got 71.5K miles on it. My biggest issue is I wished it had the 6.2L engine for better towing capabilities. Other than that ... love this truck.

Would buy again!
Just the right size for 2 adults, a child, two large dogs and two large ice chests to head to the boat with all our equipment and food. Hated to see them downsize it in '17. It has had few maintenance issues and they have been reasonable in cost. It has kept it's value over the years.

Great used car dealer
I spent a lot of time searching for a specific color, make, and model. From start to finish Chris Trombley and everyone else I dealt with at automax to push this deal through were great. There were never any surprises. Communication was excellent and the transaction was as easy as it could be for buying a car out of state.
Love my GMC Terrain!
I fell in love with my GMC Terrain when I test drove it and have not lost that loving feeling! I have received tons of compliments on it.

overall i like the truck alot, its a very dependable vehicle. it has its little quirks for a used truck. there's little things like the drivers door switch for the mirrors and the door locks that are not working as of now but i haven't taken the time to look into it as of yet. minor to me and i'm sure i can fix for a few bucks. nice riding and driving truck i would buy again.

Very Good Truck
I bought my 4x4, 5.3L ext cab at 2 years old. The records show that it had some serious factory defects (transfer case, oil pump) before I got it. Its been a great truck for me as its never been in the shop for repair. The only work I've had to do to it has been oil & filter changes, new battery and new tires. I've put 100,000 miles on it and it has 141,000 on it now. I has a few nuisance failures like high beams won't come on (the lights have been bench tested to work) and the window/mirror switches on the driver's door are failing. mechanically though, its bullet-proof.

Newest & Biggest SUV I've ever owned
The styling looks great outside & everything functions as it should. It has loads of options, heated & cooled seats & steering wheel, very cold air, big comfy 7 seats. While not a luxury-looking plush interior, it is very nice. A couple pieces of plastic molding inside are loose, a back panel I tried to take off & the visor mirror on drivers side. I've owned this for 6 months & adore it! Very roomy.

I have loved and owned Chevy and GMC midsized trucks
I have loved and owned Chevy and GMC midsized trucks since 98 when I purchased a used S-10. My latest purchase is a 2021 GMC Canyon Denali bought brand new. It's been a great truck until my power steering unit went out due to corrosion. It only has 32,200 miles on it and I have never gotten it wet other than car washes and driving in the rain which is normal conditions. I had purchased a mid grade extended warranty through GMC after my lease was up and purchased the truck. I am being told this is NOT covered due to it being external wiring. So I feel this is a manufacturing malfunction and bad engineering for water to be able to get in to cause such corrosion so beware. This is an open case filed with GM currently to hopefully rectify the matter.

Buy one if you can afford it
Excellent and reliable, only thing buyers have to do is buy a AFM disabler that you can stick into OBD2 port to avoid lifter failure (longer story, nobody wants a V8 to run in V4)
