Used GMC Sierra 1500 trucks for sale near Slinger, WI

I purchased a used vehicle from Mike Juneau's Brookfield Buick GMC last year, and a few months later discovered a mechanical issue that needed attention. The problem was something that really should have been noted or recognized during their pre-sale inspection and preparation. I reached out to the dealership, explained the situation, and provided the relevant details. The team was incredibly responsive, professional, and apologetic from the very first interaction. They reviewed everything quickly, took full responsibility, and agreed to cover the entire cost of the repair at the shop of my choice, no questions asked and no hassle. In today's world, it's refreshing to see a dealership step up like this, especially for a used car. Their accountability and willingness to make things right completely restored my confidence in them. If you're in the market for a Buick, GMC, or just want a dealership that treats customers fairly and with integrity, I highly recommend Mike Juneau's Brookfield Buick GMC. Fantastic experience, thank you to the entire team!

Great truck to own. The 2023 GMC Sierra Denali with the 6.2L engine delivers excellent power, smooth performance, and a refined driving experience. The ride quality, interior comfort, and overall build quality are outstanding. I have had no issues whatsoever, and it has been a reliable, enjoyable vehicle from day one. I would highly recommend it to anyone looking for a premium full-size truck.

The staff was very friendly and helpful. They were able to answer all our questions.

I love it the look the interior mine is a red one and it looks so good and it’s my baby and it runs so good and the technology is off the chain

I was able to contact a salesman after hours by text and arrange for a viewing the next day. When I finally arrived on Saturday evening my selected vehicle was standing by for a viewing and a test drive. Afterwards we did the paperwork and I was helped by the salesman in making a domestic wire transfer through my banking app on my phone. No cash or checks necessary! Once the wire went through the service department changed the oil, detailed the vehicle and set the tire pressures. I was able to make arrangements for a delivery to my home saving me a trip and several days of anxiety. My salesman kept me informed at every step. The vehicle I chose was in great condition inside and out which speaks to the quality of the vehicles on the lot. I feel like I got quality service even though I didn’t purchase the most expensive vehicle on the lot, by a longshot. I also had the opportunity to purchase a great warranty for my vehicle, which I found to be surprising that it was available at all. I look forward to working with Kearns again in the future for my next big purchase.

I own a 2023 Sierra 1500 Elevation equipped with the 2.7L TurboMax, and it’s been outstanding. It currently has 23,000 flawless miles. I’ll admit, I was skeptical of the 2.7 at first, but I jumped in feet-first and have never looked back. Living in Colorado, I regularly tow a 5,000-pound travel trailer through the Rockies with zero performance issues. The truck pulls confidently, handles grades with ease, and still delivers impressive fuel economy—23–24 mpg on the highway and about 18 mpg in town. I couldn’t be happier with this setup. If there is a negative to mention, that would be that after three years of ownership, the black wheels havent grown on me, and Im beginning to hate em. :) Lastly, the mpg while towing drops to 9mpg which is similar to that of a V8. All said, its been a great truck. :)

Lucas was excellent. Very efficient and has us in and out in 90 minutes. Great price on the vehicle and top dollar for my trade. Highly recommend.

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!

Did a wonderful job for me I would recommend this place for everybody great organization

I purchased a new 2019 SLT with the X1 package. It has the Red Quartz Tintcoat paint. I usually never leave reviews, but honestly this is the most comfortable, nicest loking truck I've owned , and I've ownwd alot of them. The only issues I've had was the brake software was flawed, took it to the dealer on recall and they installed a new software patch, Other then that I love the styling, performance and the interior is very nice. No regrets

Joe was awesome about taking and sending videos of the brand new Grand Wagoneer that they got on the lot before photos were even available online. We stayed in close correspondence and in less than a week, we called the new vehicle "ours." We had a. great experience with Joe and the team at Russ Darrow West Bend.

Any reviews on this vehicle is not correct. We are first owners and it’s been an excellent truck. We hate to see it go !

Only took 3 hrs for a purchase and easy . Didn?t try to get me something I didn?t want. Sales person didn?t hound or hover

2024 GMC sierra 1500 duramax 3.0 is great truck. Great ride and great MPG. 100% recommend to any prospective buyer. Love the truck and how it perform.

We purchased a vehicle. Staff was attentive knowledgeable, available, and helpful. Quick and easy to purchase a vehicle.

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

Exceptional and honest service. Ryan was outstanding .Absolutely preferred place for service with expectation that process will be open and clearly explained.

My 2022 GMC Sierra 3.0 Duramax pickup truck is a good truck. I work on a farm and I also drive an hour to see my girlfriend. For the farm, it has excellent towing capability and for the hour long drive to go see my girlfriend, depending on the weather for traveling, I can get up to 35 miles to the gallon!

Message sent directly to salesperson: Hanna, I will be recommending YOU whenever I know of someone looking for a vehicle. When someone is making a major purchase, like buying a car, it is so important to have a sales person with genuine integrity and relentless focus on the customer. Your communication throughout the process has been stellar; always keeping me updated. I appreciated that you not only focused on the sale, but also on doing proactive work to facilitate a smooth transaction on a specific day, with my family's needs in mind. That 'extra' means a lot!

I bought this after going to the dealer just to look at colors. I had a 2016 Chevy 1500 LTZ that I loved. There was my down payment and took this Denali home. Only 2 options. Paint and moonroof. I thought my chevy with 3.42 gears was quick. This one goes with 3.23's. The ride is great. Fit and finish are perfect. My only complaint is this Bose/Apple play radio is not what the 2016 Bose was.

Very easy to work with and straight forward. I would definitely recommend them or buy another vehicle through them.

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?

SIMPLY THE BEST BETTER THAN ALL THE REST! I'M STUCK ON YOURSELF MORE THAN ANY OTHER DEALERSHIP! JUST SIMPLY THE BEST, BETTER THAN ALL THE REST ?? ?

Waiting for the Refreshed 2022 AT4 was well worth it! With all the manufacturing issues today, building and shipping was slow, but understandable. Love the truck and the features! Fit is perfect and quality is #1. Pricing was too high but all vehicles are running this way. You get what you pay for and this truck is perfect! I have owned many trucks and this by far is the best. The latest features are beyond most other makes and GM has thought this truck through from front to rear.

Quick follow up. Interested in what my needs were. Overall, very responsive. Will check them out again when searching for a car.

Looked at more expensive truck with less options, bought the GMC SIERRA AT4 Turbo Diesel 6. I now only put fuel im once a month. And long distance trips are easier due to better fuel economy. One of my best investments ever.

Prentiss and Waqas were great. Being a female buying a car on my own, I never felt pressured. Prentiss always kept me in the loop about my car and was very informative. I've bought a used car and now a new car from Wilde Toyota. Always great service.

I needed a new pickup and while I wanted a Ford F150 I could not find one set up how I wanted. When I did the Ford dealers didn't want to give what I felt my trade in was worth. I got what I wanted and got a great deal on a 2024 GMC Sierra 1500 Elevation. It is even set up better than the F150's I was looking for and at a better price. I'm very happy with my purchase.

I was impressed with people at Heiser Toyota. I purchased the vehicle I was looking for and found a solid group of Heiser people that were friendly professionals whom I truly enjoyed during my purchase. Thank you and if I live long enough to purchase another vehicle I’ll go to Heiser.

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.

Found vehicle through the website, called Boucher and made an appointment to come out and take a look the same day. Was not pressured since I mentioned I had just started looking. Worked out the deal with some add ons that were needed, got questions asked and feel I had a very positive experience.

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.

We are from the Fox Valley and have purchased a few vehicles from Wilde in the past and are willing to take the drive because of the excellent experience we receive and this time was no different. Paul Basile met us as soon as we got out of our vehicle (it was Labor day weekend so it was crazy busy) and we are glad he chose us. He was extremely knowledgable on the Ridgelines which was exactly what we came for. He didn’t waste our time, gave us options and got us test driving quickly. We found ‘the one’ that was right for us. Paul made sure we had everything we needed and was great to chat with while waiting for finance to do their thing. I highly recommend working with Paul!

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. ??????????????????????????????????????????? ?????????????

Worked with Scott Sawejka . Easy, great price. 2nd car from Griffin! Super all the way around!

This truck has a jerk when changing gears sometimes. I enjoy the truck overall easy to handle and comfortable. Drive with ease sight is good when driving.

Recently purchased a new GV70. Salesperson Brady was great, very informative low pressure sale. Made us feel that much more at ease with the purchase. The entire process was as quick and easy as it could be. Love the new ride so far.

Worked with Greg on the purchase of a preowned Jeep. He was great to work with and very knowledgeable and professional. I was very impressed with the dealership and overall experience. The facilities were spotless. I would highly recommend Greg and Newman Chevrolet. Thanks again
