Used GMC Sierra 2500 trucks for sale near Slinger, WI

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

Love everything about this Duramax Denali except the fuel mileage. 13-14 Mpg tops when not towing. Bought truck cause previous was stolen. Wish I still had my 6.2 High Country!

Great!! Did everything they could to make it a pleasurable car buying experience! Great job to the team at Boucher BGMC

I've owned every other American truck and this is my first GMC. I bought the 2500 HD Texas Edition. I absolutely love this truck. It's everything I could have hoped for and more. It is able to pull my 30' travel trailer with no problems. So now when we go out with our trailer I'll have no worries. The look and feel of the truck is outstanding. The 6.6L gas engine actually gets great gas mileage. It gets about the same as my Ford f150 ecoboost. Probably better on the highway. Looking at about 13 miles in the city and 15 plus on the highway. Definitely got a better truck for the price compared to any other american models with the same characteristic and options.

Excellent in customer orientation, professional and courteous. Follow up as promised and attentiven to my customer requirements!

Nick our salesman made the process smooth, easy and enjoyable by being professional, knowledgeable and caring about my wife and I. Would recommend to all family and friends

Scott Sawejka was absolutely amazing and professional! Made it easier than anticipated. He found what was best for me! And I am forever thankful. Pretty nervous since this is my first car in the US… He found a pretty cool car and was very thorough in the features when comparing it to others… Made us not think about the intricacies of the paperwork and we were able to drive off same day… it was an amazing experience!

Excellent overall experience, sales, finance though the delivery process. Our 1st new auto in many years, really please that took place through Van Horn in Oconomowoc, WI

This truck is everything I wanted! GMC, 4x4, Lifted, Low milage. It's going to be great for my hunting and 4 wheeling! I love it!

Awesome. Very helpful and attentive. My salesman was very knowledgeable and an awesome communicator. No pressure salesman just listened

Ryan is excellent to work with! Everything went quick and easy with absolutely 0 complaints. Without hesitation they brought my new jeep right to my driveway 3 hours away from the dealership. Highly recommend and I will be doing business there again. Thanks again Ryan!

Hiller Ford provides excellent and courteous service every single time. It’s always a pleasure!

This truck would help me thru out my needs I and my family love this beautiful truck, there is no better place for me to shop than the Paso Robles Chevrolet I highly recommend them

Chad Breager & Patti Galligan went above and beyond my expectations! 2 of the most helpful people I have ever met ! I definitely will be back ! Eddie

This truck is the truck that all others should look up to. It rides great, will tow a house, runs smooth, and gets great fuel economy. The Allison transmission is so smooth. The AT4 looks great too.

After having an oil and filter change, we noticed a swishing sound. My husband pulled the air cleaner and discovered that some 'tabs' were not place properly. He fixed the problem and the swishing sound diminished. Not a big deal, but it would be nice if it wasn't there.

I was very happy with my entire experience at this dealership ship. The entire staff from the sales manager, salesman, service manager and master mechanic were all very friendly respectful and professional. I would highly recommend this dealership to anyone looking to purchase a vehicle.

What a gorgeous truck, runs good, sounds good and has all of the amenities I need although I am looking forward to their next interior upgrade.

Everything was done in a timely manner. Satisfied. Waiting area has plenty of seating. Sometimes I think they book too many cars which causes delays.

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

So far so good! This truck is the nicest truck I have ever driven. The stance, ride comfort and options are top notch. I went from a 2023 High Country that was having drive train issues but had all the creature comforts that you would expect in a top of the line truck. With the lack of confidence in that particular models 10 speed transmission issues, it became necessary to reestablish my confidence in my General Motors product.

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 dealership has an impressive slate of exotic cars, I was just looking for a lesser jag. They treated me very well not pushy and very helpful. There were no hassles in getting to test drive the car I was looking at. When I decided to walk away there was no pushback or pressure to “ run the numbers”. Both the sales person and the manager communicate with me to ensure my experience was a positive one.
