Used 2023 GMC Sierra 1500 trucks for sale near Elm Grove, WI

Worked with Rob for several months while deciding on which vehicle to purchase. He is easy to work with and very patient as I made my decision. His follow up after the sale is greatly appreciated.

Stong engine and smooth! Highly recommend for familys or someone who likes a smooth truck. Purchased new and have had zero issues since then. Love it!

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

Got the duramax diesel and getting 24 city and 32 highway is very good. Truck drives nice and is very comfortable. My 2 issues with this truck is the backup camera at night is useless (very dark) and interior lighting is not very good. You would have thought a 78k truck would have footwell lights, but it doesn’t.

Heidi and John are a joy to work with would recommend if looking at buying new or used vehicle.

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.

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

All went well from start to finish - I appreciate the good service and work done

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

My experience with Gordie Boucher was very good. We went to find a used car but ended up leasing a new car but we were never pressured in making our decision. We were given great information and the price of the vehicle was very fair. Mark Halbrooks did an excellent job from to start to finish. I would recommend this dealership to anyone.

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

Justin Peters always provides the best customer service. He offered me a loaner because the department was so busy. Turns out the mechanic was able to get it repaired by end-of-day so I returned the car next morning. I was very appreciative of his consideration. Thank you.

Found and fixed my oil leak and got me on my way in about an hour! Fair price and a great service advisor who walked me through everything before starting the work! Thank You Steve Buczak! Thank you also for the free car wash!

Hands down the experience I had was Red CARPET! Brian stayed in contact with me for 5 years because he knew how much I loved the classiness of a Lincoln and with a little time he knew I’d be back. Thank you Brian and his Manager Mike for welcoming me to the Gordie Boucher family.

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

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!

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 recently purchased a vehicle from here and had a great experience. I also use the service shop for everything I need! Great customer service in all department's!

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!

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.
