Used 2023 GMC Sierra 1500 trucks for sale near South Milwaukee, WI

Got an oil change. Took less an hour and had nice cars on the showroom floor.

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.

Every time I go there it’s great. the service staff is phenomenal. I know every time my car will be done on time and be washed and ready for me. thank you Tim, for always taking such good care of me!

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

This was a great buying experience all around. Sales management worked with me on the trade in, and everything went smooth. The vehicle is stellar! Ryan in sales did a great job pulling this one.

Excellent comfort and very good truck, it is very functional in every way, both for business and for personal, it can be said that I have the 2.7L Turbo engine and I can move up to 11500Lbs already checked by me

I received a letter from Nissan alerting me that my current lease would be expiring soon and to come in and review my options. I’m very pleased with the T&Cs of my new lease and my 2024 Altima I drove away with in just one meeting Thank you George for listening to my needs and providing this beautiful 2024 Altima

Had a great experience at Hiller, my salesman Dave was a pleasure to work with and very helpful finding the right truck for me. Then the finance guy Robert was easy to work with and ensured I got a great deal… paperwork was easy and quick! Overall great customer service and I would no doubt come back again.

I always bring my car here for service- they are honest and good at doing the work that needs to be done

This was a service related issue and I was treated like I was there most important customer by all if there staff! From the moment I drove in the service door, until I picked up my quickly repaired vehicle, like there were privalaged to help me with my all of my vehicle concerns.very satisfied with all of my service.

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.

Big thank you to David Ulwelling. He was so knowledgeable and so easy to work with. He made the buying process so easy.

I have worked with Dan Salisbury for years in regard to leasing various cars. Dan works very hard to find what I am looking for within the payment range I need. Dan never makes me feel bad for additional requests or continued questions. If there are any problems they are quickly resolved. During this last lease I had pleasure of also working with Alfonso Gomez. He was very quick at resolving small issue that I had immediately. Jason Garon in the service department is always amazing about getting my car for any oil changes or needed work. I am happy to recommend this team to others.

Great purchasing experience working with both Jim and Spike. 2nd vehicle purchased here and will definitely be back in the future for the next!

Experience was outstanding. Always professional. Very clean and extremely courtious. Very excited about purchasing my next vehicle here. Recommend to all friends and family. Thank you

It was ok. They did call with an estimate in a timely manner, and called when it was completed

I had a great experience working with Jason Archimede from start to finish. I wanted to upgrade from a sedan to a 3rd row SUV and he took the time to ask questions and listen to what was important to me in a vehicle. I did not have a specific vehicle in mind when I began my search so I appreciate all his time, effort, and flexibility to help me find what was right for me. He is very knowledgeable and I absolutely recommend working with Jason. I have nothing but great things to say about Jason and the staff at Boucher Nissan I met among the way. Thanks Jason!

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

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!

I arrived late to pick up my vehicle. Fortunately one of the Service writers noticed my arrival as he was leaving for the night. He came back to the dealership and secured my vehicle and billing. Great service.

M. Decker is a great Service Rep. very knowledgeable and honest and keeps you informed of what is being done on your car and if anything needs to be fixed

Service department is second to none! Jermaine is the best! He answered all my questions and got me in and out in record time! A++

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.
