Used 2023 GMC Sierra 1500 trucks for sale near New Berlin, WI

Whole staff was friendly and helpful. Smooth and very fast buying g experience!

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.

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.

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 was able to schedule the oil change my truck needed at a time that worked for me. The service was performed in a timely manner.

Tanner and Mark at Boucher Buick GMC of Waukesha we’re excellent to work with. Appreciated the knowledge of their products without them pushing anything on us.

Had the pleasure of having Nick Majeske provide us with an unbelievable experience of buying a new car. From start to finish and even after we purchased our car, his support and genuine desire to make sure we were satisfied did not go unnoticed. What really stood out to us was throughout the process, Nick was transparent and honest, which I greatly appreciated. He kept us informed every step of the way, and there were no surprises or hidden fees. His professionalism and integrity are truly commendable. We could not be happier with our purchase and overall experience throughout it all, and we would like to think this was in all thanks to Nick.

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.

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

I was greeted promptly when I dropped off the car and was given detail on what they were going to do with my vehicle and how long it was going to take. They even offered me a ride home. My vehicle's work was completed 2 hours earlier than expected. Excellent job!

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 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

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.

Excellent customer service and great to work with! They even delivered my vehicle to me. Nick in sales is the best from start to finish!

We purchased a used car from Robert and he was extremely respectful and went out of his way to be helpful. We needed to get a car trailer to get the car back to Louisville Kentucky. He was able to find one and reserve it for us. Everyone at the dealership was very nice and helpful. We enjoyed dealing with everyone. We will always remember the great service and friendly staff. We will remember them if we make any future car purchases.
