Used GMC Sierra 1500 SLT for sale near Delafield, WI

Everyone was very polite and friendly Tim was very helpful and and courteous he went above and beyond to get my car repaired and can?t wait to come back in for normal service

My 2022 GMC Sierra 3.0 Duramax pickup truck is a good truck. I work on a farm and I also drive an hour to see my girlfriend. For the farm, it has excellent towing capability and for the hour long drive to go see my girlfriend, depending on the weather for traveling, I can get up to 35 miles to the gallon!

The employees were professional and friendly. They took their time to understand our needs and preferences to help us identify the best vehicles for us. They never pressured us or rushed us to make a purchase.

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!

I travelled out of state for my purchase and Brad did a great job at answering my multitude of questions! They had a driver pick us up at the airport(1 hour away), washed and filled up the car. Brad sat down with us helped us find some local eats and got us convict way with ease. Paperwork was quick as well. I can't thank them enough for making this car buying experience very productive and hassle free! Thanks again Brad!

Great truck to own. The 2023 GMC Sierra Denali with the 6.2L engine delivers excellent power, smooth performance, and a refined driving experience. The ride quality, interior comfort, and overall build quality are outstanding. I have had no issues whatsoever, and it has been a reliable, enjoyable vehicle from day one. I would highly recommend it to anyone looking for a premium full-size truck.

Ricky was amazing to work with! He was friendly, honest, and made the whole car-buying process quick and stress-free. He answered all my questions and made sure I got the best deal possible. Highly recommend Ricky if your looking for your next investment.

I bought this after going to the dealer just to look at colors. I had a 2016 Chevy 1500 LTZ that I loved. There was my down payment and took this Denali home. Only 2 options. Paint and moonroof. I thought my chevy with 3.42 gears was quick. This one goes with 3.23's. The ride is great. Fit and finish are perfect. My only complaint is this Bose/Apple play radio is not what the 2016 Bose was.

Excellent customer service and great prices compared to other dealers with a Wide selection of vehicles. bought my first car from here and definitely coming back when its time to replace it.

This truck is the base model and that is exactly what we were looking for. A good solid truck without all the fancy technology. It drives like a dream, handles just as well and the interior is sleek and well designed. Perfect black on black exterior.... a man's truck.

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

Overall I am very happy with my new Truck. GMC however needs to address their software glitch where the display screen intermittently stops working or the audio cuts in and out. I keep hearing a software update is being worked on but that was a while ago?

Offered more for my trade than the other dealership I was working with. Friendly staff, I will be coming back here for my next one

I have the 1500 double cab with standard bed. The reason I have this vehicle is I really like the 6.5 foot bed. The crew cab with same bed is just too long. The things I dislike about this model is that it only comes in the SLE model. For the 2025 that means the external mirrors do NOT have a power fold in and it does not have a seat memory for more that one driver. The power fold in for the mirrors is extremely important to me.

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

Any reviews on this vehicle is not correct. We are first owners and it’s been an excellent truck. We hate to see it go !

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.

Good afternoon everyone, yes, I’m a lady and I’m an owner of a 2017 GMC Sierra 1500 Denali, it has a V8 motor fully loaded sunroof & also it has heated seats & steering wheel for the cold winter months & in those hot summer months you have A/C seats nothing better than that am I correct? It’s been times like that wouldnt trade for the world!! So for all you ladies who think BIG TRUCKS are just for men, go out there & buy one have them put on some electronic slide in/out rails & go out & show the shows the boss!! lol 😄 I’m out looking for a new one now either a 2500/3500 pearl white

It was all handled very well. The man who took my order handled it very professionally. The service was completed in a timely fashion and he explained all that had been done and may need to be done in the future. I appreciated it very much.

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.

Great!! Did everything they could to make it a pleasurable car buying experience! Great job to the team at Boucher BGMC

I purchased a new 2019 SLT with the X1 package. It has the Red Quartz Tintcoat paint. I usually never leave reviews, but honestly this is the most comfortable, nicest loking truck I've owned , and I've ownwd alot of them. The only issues I've had was the brake software was flawed, took it to the dealer on recall and they installed a new software patch, Other then that I love the styling, performance and the interior is very nice. No regrets

Worked with Matt to test drive a Gladiator I had researched online, I had a few moving parts in my deal I was working through. He was patience was appreciated, ZERO pressure!! I met Abs, to talk through what I was looking to trade, etc. he was transparent and open with what he could do to help me with my purchase. He’s a solid young man!! When I took delivery working with “Dan the finance man”, offered alternatives BETTER, than what I was planning to bring to the table, the process was effortless. We all don’t “enjoy” the car buying experience but the fellas at Burtness have a great operation and we will be back for my wife’s Grand Cherokee later this year!!

I love it the look the interior mine is a red one and it looks so good and it’s my baby and it runs so good and the technology is off the chain

I purchased a new Jeep Wrangler Rubicon X from Uptown. The entire experience was incredibly positive. There was no pressure. My trade in value was fair. Overall I was very pleased with my purchase and the process of buying the vehicle.

Am in disbelief every week at the Gas Pumps. Thou a big truck, mileage per gallons are 18 +. Last week it was 22.8. This week 19.78.

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.

Waiting for the Refreshed 2022 AT4 was well worth it! With all the manufacturing issues today, building and shipping was slow, but understandable. Love the truck and the features! Fit is perfect and quality is #1. Pricing was too high but all vehicles are running this way. You get what you pay for and this truck is perfect! I have owned many trucks and this by far is the best. The latest features are beyond most other makes and GM has thought this truck through from front to rear.

Late review, We bought a Jeep Cherokee Latitude from this dealership this summer. The Salesman Adam, and Service manager were outstanding! Test drive vehicle (unfortunately on a rainy day) didnt hear or discover any issues. Took car home and next day discovered very noisy road noise and undefined noise from front of vehicle. Working with the team to discover the problem althought time consuming was a far more pleasant situation than expected. The entire time the team worked on the issue provided constant interaction, communication and updates. Just wanted to assure the team that I was completely happy and AMAZED that the situation was taken care of professionally. Thank You Gary Gregory

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.

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

I bought a 2019 GMC Sierra Elevation. I traded in a FULLY loaded 2015 Sierra SLT, that I was really sad to see go, but the Elevation really sold me on styling and ride quality. I lost a couple high end bells and whistles, but the overall performance and look of the truck make up for it big time!

Sales people were nice and friendly . I thought I ended up with a good deal on my trade and buying a new vehicle . They need to get better coffee.

The only thing is I wish when I got my 2024 Buck Envista they would have told me to wait until 2025 or 2026 to get that car because they added so much more to the model that I have and that really sucks.

Great performance, hard to clean, everything, I expected. Getting lots of compliments and head turning. Stomping with thee BIG DAWGS!!!! Good gas mileage on highway.

Impeccable Serice Jeremy Simonson, Brandon Gilsch were incredible. They handles my issue with the utmost professionalism and speed. They took the time to investigate and take care of my issue.

Smooth ride strong motor decent gas mileage inside cab is loaded and very tastefully done along w easy access to knobs. Plenty of room. In back seat ! Aclassy looking Truck with a tacky looking owner!!
