Used GMC Sierra 2500 trucks for sale near Lannon, WI

I went in for an oil change and came out with a new vehicle. The sales staff are amazing. Friendly, accomodating and efficient. The manager in the service department pays attention to the details. He has been very friendly and accomidating.

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.

Jason Archimede came to us as soon as we walked in answered all our questions and after explaining what we were interested in quickly found us the car we were wanting within our budget. He kept us comfortable and entertained our toddler making it as smooth as possible and made sure we were 100% satisfied and setup before driving off the lot

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.

Great place to keep going back too for all my service needs even for my oil change always prompt and keep me up to date , the big for me is they don?t try too sell you extra stuff and they let you know when something needs to be done in more than a timely manner , keep it up RDM

I paid over $106,000 for this truck with warranty. Do not care much about miles per gal. at that that price range. Just too much truck for me at my age.

Fantastic employee assistance and buying experience. Huge thanks to “LJ” and Dogan for getting me hooked up with an amazing Toyota Camry

One very awesome vehicle. Checks all the boxes you need in a truck and exceeds expectations on quality, performance, and looks great ,too. Love my nre truck.

We purchased a 2025 Explorer and the entire process was painless. A big Thank You to Alan and the entire staff at the dealership.

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!

I like how Omar the seller was helping me out on getting the perfect truck for me thanks to Omar because I?m very happy with my new truck

This was my first experience at a dealership, but I did extensive research beforehand, and had an idea of what to expect. My sales consultant, Lukas Hale, was down-to-earth and personable - and I sincerely enjoyed working with him. In terms of finance, they did honor my OTD price, but sales were a bit high pressure and I would like more time to review the fine print before signing.

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.

Wonderful truck. Has had zero problems. I am trading for a new one. Truck is all original with no modifications. Truck is in excellent condition.

I purchased a used Porsche at this dealership and highly recommend them. The entire process was actually pleasant with exceptional customer service. My salesman Jeff was knowledgeable and extremely prompt with replies, whether it was after hours or his day off. His personality and sense of humor makes him such a pleasure to work with. The entire team from sales and finance managers to the service advisor I dealt with were all straightfoward and most helpful. I live in NH and they made all the arrangements to have the car transported to my home. Truly a great car shopping experience.

Great power and yet great economy. Love the safety features with the cameras and side vehicle warning. Camera that shows side of vehicle, including trailer when turn signal is on is great. Also appreciate the bed camera for hooking up gooseneck trailer.

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

Steve Svec, Product Specialist, did an excellent job assisting us with the purchase of our new 2020 Ford F150. He was very well informed about the vehicle and was very professional. He is an asset to the Lynch team!

I love my 2021 GMC Denali 2500HD. I have gotten more complements on this truck than any other vehicle that I have owned. I get great highway fuel milage average 19-26mpg,which is great for a heavy duty truck!

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.

This dealership is Awesome and easy to work with Will be back! Make sure you get your floor mats.

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

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.

Ours sales person was excellent, without Cecilia I don?t think we would of made it through the long process. Getting a trade in for our car took way to long. They need speed up the process! Also the finance part was backed way up and also need to speed that up!

Excellent always satisfied when I leave the dealership. Salesman Matt Kreckler and Service Advisor Craig Pozarski very efficient and knowledgeable. A pleasant experience as usual.

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

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.

Had a awesome experience with Chad Braeger when purchasing my Jeep Wrangler. Everyone was helpful and willing to answer any questions or concerns I had. Thank u, for making me feel comfortable thru out my buying experience. Lisa
