Used GMC Terrain SUVs for sale near Mequon, WI

The staff at Rosen Kia were excellent. Sherri who was my initial contact was very responsive to my texts and not at all pushy. Nate, our salesman was enthusiastic and polite. The sales manager was transparent about pricing. It was a good experience. And we are delighted with our purchase.

We love our GMC Terrain !! We recently purchased from former Mike Duman in Suffolk, VA which is now Priority Mitsubishi our salesman Mr.Knight is highly recommended He’s a man of God, great respectable person, and very professional!! Whenever you are in the area and you’re looking to purchase a vehicle contact Mr.Mervis Knight !!

Our 2021 Terrain SLT is really a nice auto. Gets great 30 MPG approximately, But, 0 to 60 is lacking horsepower. Great Little highway auto. Comfortable.....

Ronnie was top notch and easy to work with. We told Him that we were just looking and was not interested in buying anything when we came, we were Just looking, and he respect that. We found a car but we have 7 more dealerships to visit that day and the other sales guys were very pushy and wanted us to buy that day. We came back and test drove a Car with Ronnie, and we worked out a price and everything went so smooth and easy. I would recommend AM Auto to be your 1st choice before you got the Big Box Dealer. Thank you for all your help

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.

Very welcoming and made the purchasing process of buy the vehicle very fast and easy. Overall friendly and easy to talk to dealership. Five stars!

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!

Staff very polite, friendly, no pressure and willing to work with me! Facility was very clean! I bought a 2025 Chevrolet Trax. I love it! A+

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!!

I purchased a new Silverado RST and Tony's help made it extremely easy and smooth. The service department's support, communication, and work adding accessories were above and beyond my expectations.

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

The service I received was beyond exceptional! Cody in sales took much time to explain all features my suv held. He thoroughly answered all of my questions and made sure all of my expectations were met. He took the time to interact in a fun and relaxing way with my nephew as we waited for financing. Patty in financing was beyond incredible. She went above and beyond to be sure my budget was met and was very understandable and patient! I could have not asked for a better and stress free experience!!

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.

Our salesman Dan, was professional and honest. Very helpful and we love our new vehicle.

I brought this truck in 2019. I kept taking it back to the dealership to get tweaked several times. Once it was figured out, never got any problems ever again. A little weak on the power side, but, other than that, its a magnificent vehicle. A total work horse. Great on gas. It is totally worth it.

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!

The sales crew made for a very good and smooth deal on the sports car of my wife's dreams a Mustang convertible. A super smooth sale and financing.

LOVE< LOVE< LOVE< LOVE< LOVE< LOVE< everything about my SUV, wouldn't trade it for the all the money in the world, and trust me...The Dealers keep reaching out trying to get me to TRADE because it only has 54K miles on it. They always say it's because it's in great demand. I'm sure it is.

We test drove the car on Tuesday and everything went well. Bought the car on Saturday and it was making some odd noises. Brought it back and they had it fixed by Monday. Really enjoyed working with them.

Satisfied with my vehicle. This vehicle is just right for my family of 5. The interior is really nice. I would recommend this car to anyone.

Best car buying experience. Our sales representative, Angel N. was nice and didn't play any games, got us into our new car in only a few hours. The team at Kunes was great to work with, only disappointment is that they aren't closer to where we live.

One of the most attractive looking t cars GMC has ever designed. Looks just like a Lexus. Extremely roomy. Love every aspect of my Terrain.

Unexpectedly Surprised! Jim, aka Turk, the 2nd generation owner of Diamond Jim’s is a 10 out of 10 and if the scale was out of 100, he would be a 100 out 100. Here’s my story: I have had over 35 Corvettes and had been looking for a 2015 Corvette - Daytona Sunrise Orange Metallic - convertible - 7 speed manual for 18 months and finally found one and it was at Diamond Jim’s in Milwaukee, WI. I called and spoke with Jim and he suggested that we FaceTime and we did for it a good 20 minutes. Car was great except the tires were a little worn … not a problem … I put a deposit down and scheduled a flight from Southwest Florida to Milwaukee with the plans of driving it back 1,430 miles! 🤪 I have never flown cross country to buy a car before so I was a little nervous to say the least. We arrived at Diamond Jim’s and met Jim … the car was everything he said it was and better (fair price too)! This is when things turned to the unbelievable and quiet frankly, shocking … Jim said he felt uneasy selling me the Corvette with the slightly worn tires so he replaced them with brand new OEM exact factory replacement Michelin tires!! I have another, identical Corvette and recently replaced the tires on that one for a whopping $2,000!! 🫣 Jim apologized for not giving me a full tank of gas (it was 1/2 full) … I said, “Let me see, a full tank of gas or $2,000 worth new tires!!” He laughed and said the construction in front of his dealership prevented him from filling up the tank! He’s a true gentleman. Then, to add to this amazing person that I just met, Jim called us about 2 hours later during our drive home making sure that we were doing OK!! Lastly, we plan on buying another car within the next year and there is no doubt that we will call Jim, take his word for the description of the car, pay for it and ship it to Florida … we drove the 1,430 miles in 28 hours and we don’t plan on doing it again! 😁 I have been buying cars since the late 1970’s and I have never had a better experience than I did with Jim at Diamond Jim’s and I give them the highest recommendation possible!! 👍

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.

Very satisfied. Everyone is very helpful and always answers my question !!!! I have been purchasing my Buicks from you for the past 12 years. Love My Buick!!!! I have a 2024 Buick Encore ST.

The GMC Terrain is a very dependable auto that I have had no issues. The model is the AT4, which has the headsup display. Interior is nice with leather and all the electronics options.

They gave me some cookies and were very nice. And the car was super cool.

25 000 miles on it so far No issues at all Power is fine Bluetooth is terrible Memory seats need work Lumbar is a bad design

Great service and I had a very fun awesome sales rep ( Danita Graham help out on choosing a car. I’d recommend her to anybody 👍🏾

Estamos muito felizes com nosso carro muito confortável muita seguro . Dar confiança ao motorista espaço bom para minha família eu minha esposa e dois filhos

Everything was great! Started out with Josh (who could not be there the day we could come), so Michael helped us and answered every question we had. Felt great about the deal and we thank Michael (and Josh) for everything??

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

Great experience from beginning to end!! Extremely knowledgeable great customer service actually the best customer service I've ever experienced would definitely buy another car from them and recommend them to friends and family.

They provide Friendly service. Nice atmosphere. Very Fair price. It was a Great experience. Love Boucher dealerships.

I’ve had an amazing experience with terrain Denali. I had it for 3 years and it was one of the best cars ever. Everything worked perfectly no issued at all! Loved it

Very pleasant auto buying experience. Great people to talk with and fair in their negotiations. I pointed out a scrape on the vehicle and they made a fair adjustment. It was the perfect buying experience … until I woke up this morning. I went out to wash the bugs off from driving home the night before and found several breaks and cracks in the grill and fender that I didn’t notice when I bought it the night before. They of course didn’t point them out to me. All I can say is, “Shame on me,”. My responsibility for not looking it over more closely. My bad not them. Buyers Beware! Look over every inch, twice. Everything is made of plastic these days.

To be honest, this SUV impressed me with the great performance even with the small 1.5 liter engine, and huge space inside, it rides like a bigger vehicle, very responsive on the highway and very quiet cabin. My wife really liked it.
