Used GMC trucks for sale near Sullivan, WI

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.

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. :)

Since 2014 I have purchased three new cars at Janesville Subaru (a Legacy, Forester Premium and recently a Forester Limited). Allow me to share my experiences. The salesperson I deal with is Deana Watry. Deana sold me my first car from this dealership – but it was not my first Subaru which was purchased back in the 1980’s! I was impressed with Deana from the start. She was able to answer questions and get me into a vehicle my wife and I were seeking. If Deana did not know an answer she would find it. Over the years of brining cars in for servicing Deana maintained contact and ensured things were continuing to go well. As a buyer in his late 60’s I have dealt with a variety of salespeople in other dealerships selling other makes and models. Most in sales are simply out for themselves and will tell you whatever they like to get a sale – buyer regret usually followed. Deana is personally interested in helping us get what we wanted within our budget. She understands that customer satisfaction is about integrity, being honest, follow-up and continuing to build trust. Yes, I will continue to buy from Deana – I hope you do as well. Now for the dealership. After purchasing a 2015 Legacy the driver’s seat could not be moved forward or back. A Rockford Subaru dealership wanted $2,000.00 to replace the seat. Subaru of America had me reach out to Janesville Subaru to have them evaluate the seat. Within 10 minutes the problem had been fixed. A quarter had fallen into the seat track and stopped the seat from moving. There was no charge. I gave the bent quarter to the service manager with my thanks! I’ve only had service done there since. Buying tires - they are competitive with the large retailers. This means free rotation with oil change and free car wash. Travel is part of my job. Having a dependable car is essential. The dealership is good at keeping me updated about regular maintenance. In the service department, Jonathan and others work to schedule according to your time frame. It has been common for me to get in on short notice. I like the dealership and believe you will as well. Be sure to ask for Deana if you want to buy.

Am in disbelief every week at the Gas Pumps. Thou a big truck, mileage per gallons are 18 +. Last week it was 22.8. This week 19.78.

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.

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 !

My service experience was excellent, as usual. This time was the best however, the issue was repaired within 90 minutes at a much more reasonable price than expected. Always love seeing the birds also.

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!

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!

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.

I purchased a 2025 Mazda cx70 with the help of Kenneth at Boucher. He wasn’t pushy and actually made the whole car buying process a little less terrible! The manager was also willing to work with me on numbers to suit my budget. If you’re in need of a Mazda, ask for Kenneth!

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!

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

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.

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.

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.

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.

2021 GMC sierra 1500, 5.3, crew cab 4x4, 21000 miles. brakepad monitor lites up. dealership says needs brakes and rotors in back. one mo. on warranty. our rural roads dirty up the monitor. Needs new monitor. brakes look great to me. No noises. dealer says parts on order GM strike. Can't replace myself cause of computer...

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!

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.

Had a great test drive in a Lincoln Nautilus. Marco was very knowledgeable about sales.

My truck has a great appearance, inside and out. It is a pleasure to drive; and rides and performs great. It is the best truck I've ever owned.

Easy to work with, low pressure, solid information, and overall good people. Shayan Khan was extremely helpful and let me take the lead, answering questions and pointing out additional considerations without being overbearing. Recommend!

During our recent visit to Russ Darrow Wauwatosa Kia to check out the pre-owned car options, I was lucky to be assisted by "Brianna Holbrook" —she was friendly, professional, and made the experience enjoyable. She was clearly invested in helping me find the right car from the very beginning, with patience and professionalism, they walked me through the vehicle’s history, specifications, and overall condition, addressing my queries with clear and honest responses, I especially appreciated their transparency about pricing and willingness to accommodate a test drive without pressure. Thanks to Brianna professionalism and friendly approach, I felt confident and well-informed throughout the process. Brianna Holbrook is an outstanding Sales & Leasing Consultant, and I wholeheartedly recommend her to anyone seeking reliable and supportive service. The gorgeous Ford Edge SE is finally here! Huge Thanks to RUSS DARROW WAUWATOSA KIA.

Great place to buy a car very friendly would highly recommend them everyone was very helpful and gave us a good price on a vehicle

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.

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

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??

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

I bought my 2020 with 36k miles a couple of years ago and I now have 60k miles of trouble free very enjoyable driving. It was expensive, but worth every penny. The ride is so quiet and comfortable my wife and I prefer traveling in it instead of our 2018 Acura MDX which we also love. The 5.3 V8 has plenty of power and towing ability. The multi-function tail gate is genius, I hope to never be without one again. We so enjoy all the bells and whistles, especially the wireless phone charger. So glad I bought this truck!

I brought a lemon of a car in to trade and Jacob spent a few days working with me to find the best replacement. I drove off the lot relaxed with a great running car. Thank you.

handles and drives great, the electronics don't always work, mirrors don't always work, spray with wd 40, check engine light, EVAP culprit, auto nation has no luck with this, will drive it till the warrenty expires and its back to ford for me

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!

Worked with Matt to test drive a Gladiator I had researched online, I had a few moving parts in my deal I was working through. He was patience was appreciated, ZERO pressure!! I met Abs, to talk through what I was looking to trade, etc. he was transparent and open with what he could do to help me with my purchase. He’s a solid young man!! When I took delivery working with “Dan the finance man”, offered alternatives BETTER, than what I was planning to bring to the table, the process was effortless. We all don’t “enjoy” the car buying experience but the fellas at Burtness have a great operation and we will be back for my wife’s Grand Cherokee later this year!!

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
