Used GMC Sierra 1500 trucks for sale near Mukwonago, WI

Proficient Honda dealer. Frank, our sales person did a good job with our purchase and was the key reason we made the purchase. He did not overly pressure us to buy the vehicle and provided the optimum amount of sales support. I would use him again for any future vehicle purchases.

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.

Basic maintenance and tire rotation, I was in and out in an hour. Kudos to Zach Schuett, Asst. Service Mgr.

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!

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.

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?

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!

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.

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

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!

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. :)

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

Let me start by saying I have the AT4 model with the Duramax 3.0L diesel. I had a 2024 Elevation with the 5.3L V-8 that I bought to pull my 22’ camper. While the Elevation pulled my camper fine it drank the gas like it was on a binge. And with a 26 gallon gas tank it seemed I was filling up every couple of hours. After one trip to Nova Scotia I knew something had to change. I pulled my camper out west to Yellowstone and back through Arizona. It pulled like a champ and fillups were a lot more manageable. Even driving the speed limit out west I still got four to five mpg better than with the gasser. I liked the Elevation but I love the AT4. Way nicer ride and great handling. I get 30 per gallon of diesel on the highway if I drive the speed limit but I got it to tow with. I added a Titian replacement fuel tank so I have 43 gallons instead of the 26 it came with.

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.

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.

Tim is an excellent salesman. We haven't closed a deal yet due to other issues not relating to Palmen Even though they are an hour and half away from me, they earned my future business.

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.

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 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

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 got the Honda Accord. Ken, the Sales Consultant knows his field. It’s just frustrating because there’s a long wait for the financing office. We stayed 5 hours in the dealership & it’s mostly waiting for the financial office to process our papers.

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.

I live in Waukesha I couldn't make a deal on an incoming car, but I ended up ordering the car to spec from another dealer who had three allocations the dealers in Iowa, but it's gonna cost me $600 to ship the car which is not that bad because I'm saving thousands of dollars I previously purchased another brand of vehicle from this dealer as well but they're one of the largest Ford dealers in the Midwestern United States, which is how they ended up getting my business originally they have a big presence on all of the ford forums so the deals are out there people you just have to look for them. It's not 2022 anymore And ford sales numbers of public Especially when it comes to models like mustangs. But at least I tried to get my local deal of the business first and I provided evidence to them of the deal I could get because you know how it is. They always say that you're lying about the deal you can get. Etc etc etc Do your research you can always save money. It's a Ford. It's not a Porsche GT 3RS OK.

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!

Great place for shopping for a new vehicle. Great salesman Enrique made a sweet and smooth buying process. Highly recommended not once did I feel hurried or pressured on my purchase.

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.

everything went well. truck was repaired and runs well. tech found the thermostat was faulty and replaced it. I was charged $620, it seemed high to me.

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.

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!!

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?

every service maintenance we have on our car is the same. excellent!!! everyone is nice and friendly. work is great and always walk away with a great feeling. thank you.

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 !

Cheryl was great, and the process was quick and painless. A great experience at Serra.

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!

Just started looking for different car. No pressure. Let us look at our pace and we're available to answer questions as needed. Good experience.

This was a fabulous experience. I now have a new dealership and a new set of car guys! Thank you for getting me setup with my new Silverado!

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.
