An AWESOME Vehicle!
This wasn't the vehicle I'd gone to the lot to see... But it was parked 2 vehicles down, and the price was $3000 cheaper!! It even has more bells and whistles than the Toyota I'd initially planned on getting. Awesomeness!!

Our experience at Woody Buick was exceptional from start
Our experience at Woody Buick was exceptional from start to finish. My wife and I were extremely pleased with the level of courtesy and professionalism we were shown. Jaime Liska was our amazing salesman and we couldn't have been happier! The manager came out to meet us, Bill Stacek, and we talking our conversation with him and his whole team! The sale of our Buick was as discussed and very honest. I know this sounds too good to be true, but coming to Woody Buick really was a blessing to us takeout every need was taken care of from all the Team members at Woody! Both my wife and I had terrible experiences elsewhere, so this experience truly was appreciated. Well done to Woody Buick! 👏 👏
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.

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

Love Our New 2023 Denali Terrain!
We purchased the Denali Terrain 2023. The car is great. I have had four knee surgeries and needed a car to get in and out easily and comfort seating. The controls for adjusting the seat just the way you like are great. I am troubled also by back problems and totally love the heated seat when needed. Sometimes I just want to ride around and turn the heat on and adjust seat so my back feels better. The different controls and are numerous. I love the safety control warnings and info with traffic. The screen is fabulous and helps so much. When ever I park I like to drive in and park and then hold on brake put it in reverse so the screen then comes on and shows how I parked. I like the levers in cargo area for putting seats down and also like how flat they sit. Plenty of room. The back seat is roomy even when person in front is back. Enjoy being up higher than a vehicle. I feel I can see more and it also makes me feel safer. The Terrain looks beautiful and love all the chrome in front. The car seems bumpy but not as bad as our last. The roads are in rough shape here. It has a lot of pick-up my husband demonstrated that to me and he wont be doing that again unless it is necessary. It is a turbo 4 cylinder and can not believe the power you feel. All in all Iove the car and getting good mileage. Purchased car from Boucher in Waukesha. They were not pushy. Explained everything in detail and were very fair. Great place to purchase!

A Truly Pleasant and Honest Car-Buying Experience I was
A Truly Pleasant and Honest Car-Buying Experience I was feeling really upset this morning because of a dealership that kept changing the price, but then I happened to find a car that caught my eye on a website. Then I made an appointment at Merchants Auto for a test drive. At first, the place looked a bit quiet, and I wasn’t sure what to expect. But from the moment I walked in, I was impressed by how friendly, professional, and proactive everyone was. There was about a $3,000 difference between the price I saw online and the one initially quoted at the dealership. I mentioned this and also showed them an offer I had received from another dealership the day before. I told them that if they could match that deal, I’d sign right away. They worked hard for nearly an hour — checking different options, running numbers — and finally made it happen. I signed the paperwork and made the down payment on the spot. Even better, the finance rate they offered was about half of what another Boston-area dealership had quoted me, which helped offset that $3,000 difference. What impressed me most was that the price we agreed on during negotiation was exactly the same when it came time to sign the papers — no hidden fees, no surprises. It was a bit of a drive to get there, but it was absolutely worth it. I’m genuinely happy with my purchase and the entire experience. Highly recommended — I’ll definitely come back here when it’s time to replace my wife’s car!
Denali made the difference for us
We are very happy with our Terrain Denali. Our first choice was the 2023 Lincoln Corsair 1a but there are no in inventory. The Terrain Denali was 1b. Great styling exterior and interior

2015 GMC Terrain Review – Reliable and Comfortable
2015 GMC Terrain Review – Reliable and Comfortable SUV: I purchased the 2015 GMC Terrain as a reliable daily drive, and it has exceeded my expectations in many ways. The interior is spacious and comfortable, with high-quality materials that give it a premium feel. The seats are well-padded, making long drives enjoyable. In terms of performance, the Terrain delivers a smooth and stable ride, with responsive acceleration that meets my needs. The fuel efficiency is reasonable, which helps with long commutes. The exterior design is bold and distinctive, giving it a strong road presence. Reliability has been solid, with minimal mechanical issues over the years. Maintenance has been straightforward, and the vehicle has held up well. Additionally, my purchase experience was fantastic, thanks to Claudia Reid/Sales. She truly took the time to negotiate pricing and ensure I got the best deal possible. Her dedication and professionalism made the entire process seamless. Overall, the 2015 GMC Terrain is a great choice for anyone looking for a comfortable, spacious, and dependable SUV. Would I recommend it? Yes, especially for families or commuters seeking a balanced vehicle. Thank you, Auto Club of Edison!

Great vehicle, 65,000 miles and not a single issue, hoping to get atleast another 100k miles out of it. Extremely reliable. A family member of mine bought a Honda that broke down at 16,000 miles and got stranded. Would absolutely recommend a 2018+ terrain

My salesman Frankie was awesome. Took the time to show me all the features of the truck, made sure I knew how everything worked. Can?t say enough about him.
Bought the car CPO in summer 2021 with 38k miles.
Bought the car CPO in summer 2021 with 38k miles. Now being summer 2024 with 90k miles and I’ve mostly had good luck with the car and its components. I have the extended warranty through 100k miles but I feel like all American cars are built to fail after the warranty runs out. Overall great car: I have the 2.0L turbo engine with 9 speed auto and AWD. AWD is great when turned on, grips the road well, and to be honest the 2.0L has a TON of power; way more than you need for a compact SUV! I had a quick issue around 65k miles where the service traction control and stability light came on for 15 minutes. Dismissed itself and haven’t had an issue since. At 75k miles, it was during the winter time, the car would display “park break realized” and “service traction control” when the auto start stop would kick back on (there’s no way to shut off the auto start/stop system). No issues and lights but the messages would pop up and dismiss themselves. Little did I know it was my battery dying and my mechanic said “some wires were loose” and he tightened them up. Haven't had an issue since I got a new battery. Last thing that happens is sometimes when you have Apple CarPlay going and you unplug the phone, the infotainment system will freeze and no Bluetooth, usb, or CarPlay will work for the reming duration of the ride unless you stop the car and let it sit for at least 30 minutes. Simply shutting it off and turning it back on never worked. Overall I give this car a good rating for 0-100k miles. I am pleased with the car but looking for something bigger soon. I think I did overpay a bit for it ($30k for 38k miles) since I got it summer of 2021 when new cars were nonexistent!

Gas and diesel terrain
I have owned 5 of the 2018-19 terrains. I have had the 1.5 gas, 2.0 gas and the 1.6 diesel. The power on the 2.0 is awesome. Mileage on the 1.5 is good. Mileage on the 1.6 diesel is great. I have 336,000 miles on my diesel. It has had lots of issues due to emissions and transmissions. Last week it got a new engine as well. The car is a great car but I would recommend the 1.5 gas for most people. The terrain is comfortable and makes a great work or travel vehicle. Size is easy to park with plenty of leg room.

Great savings on gas and mileage, very reliable and comfortable. Saved my life when I was in a big rig truck accident as driver side and front side bags deployed. I've become a GMC customer for life as I will be looking forward to buying another GMC SUV.

My service advisor had such a great attitude with welcoming me in and smiling as he assured he would make sure my experience was going to be great. And it was thx to him. It was refreshing to have a service employee appear to love his job, or he pretending really well. Either way it was appreciated. A great attitude goes a long way!
We love this automobile.
This is a higher trim model with the bigger 4 cylinder engine (2.0 vs. 1.5) most of the options including Bose sound system. We love our pick and the only reason I gave 4 stars to comfort is the ride. Granted it rides nice, but you only get 5 stars from heavier sedans. Trucks and SUV's just aren't designed for that really smooth ride. Definitely would recommend the 2.0L engine if you tend to pass on a 2 lane road or need to pull out quick in traffic.

What a wonderful experience to be able to purchase a car for the advertised price and get a fair price on your trade in. Buying a car should be as enjoyable as my experience was at Ferman Chevrolet!
One of the best looking suv's on the road. Highly
Extremely happy. Ride comfort, controls, comfort, looks, quietness, Quality. They should've kept the 2.0 turbo. But this engine not bad at all. Can't wait to get another.
