Used 2023 GMC Sierra 1500 trucks for sale near Hartland, WI

David Ulwelling has the most refreshing approach we've ever experienced. He is honest and straight-forward, helpful, professional, and handles every detail. David makes the buying experience so easy, it becomes effortless. David is customer service, "customer first" in his style. He makes you feel important and as if you, your desires and needs in a vehicle, matter. He will be our sales person from now on. We are newer Cadillac owners but so far love the dependability and reliability of our SRX. We have found that Crest Cadillace of Brookfield is full service and great to deal with.

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.

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++

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

You did a great job helping us out. We needed a new battery and you had it and put it in right away.

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

Our salesperson, Elijah, did a great job. When picking up our purchase, he spent as much time with us on a used Jeep GC as a new one. Demonstrating the vehicle features and connecting our phones to uConnect. Patiently and without being overbearing, I was impressed and would recommend him and the dealership.

Dustin the service advisor was really helpful - took care of my issue with my keep grand Cherokee. Even though it was really busy, still was very friendly and solved the issue quickly. Definitely recommend this dealership/service hub.

The quick lube part of hiller is great. They’re very efficient, answered my questions concerning other needed work. They also have a nice clean waiting area

I had an outstanding experience working with Ty on my recent vehicle purchase. He was consistently responsive, knowledgeable, and never pushy throughout the process. We don’t purchase new vehicles often, but when the time comes again, I will certainly return to Ty. I highly recommend him to anyone looking for a straightforward and positive buying experience.

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

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.

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!

EXCELLENT- HAD SOME BODY WORK DONE WAS THERE A COUPLE OF DAYS AND LOOKS GREAT

Great service. Straightforward and easy process. Would highly recommend to anyone. Will buy again here.

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!

Overall pleasant experience. I had some issues arise in the purchasing process, but they were all addressed timely and satisfactorily. Nice people to deal with.

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.

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.

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
