Used GMC Sierra 1500 trucks for sale near Mukwonago, WI

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.

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!

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.

This truck has a jerk when changing gears sometimes. I enjoy the truck overall easy to handle and comfortable. Drive with ease sight is good when driving.

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.

Let me start by saying I have the AT4 model with the Duramax 3.0L diesel. I had a 2024 Elevation with the 5.3L V-8 that I bought to pull my 22’ camper. While the Elevation pulled my camper fine it drank the gas like it was on a binge. And with a 26 gallon gas tank it seemed I was filling up every couple of hours. After one trip to Nova Scotia I knew something had to change. I pulled my camper out west to Yellowstone and back through Arizona. It pulled like a champ and fillups were a lot more manageable. Even driving the speed limit out west I still got four to five mpg better than with the gasser. I liked the Elevation but I love the AT4. Way nicer ride and great handling. I get 30 per gallon of diesel on the highway if I drive the speed limit but I got it to tow with. I added a Titian replacement fuel tank so I have 43 gallons instead of the 26 it came with.

I found Phil Aleio to be very responsive to questions and Kaifer Zulesdorf especially enjoyable to work with. I trust him and plan to trade cars back and purchase future special vehicles. Great experience from a Wisconsin dealership!

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

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.

2021 GMC sierra 1500, 5.3, crew cab 4x4, 21000 miles. brakepad monitor lites up. dealership says needs brakes and rotors in back. one mo. on warranty. our rural roads dirty up the monitor. Needs new monitor. brakes look great to me. No noises. dealer says parts on order GM strike. Can't replace myself cause of computer...

Contacted them over email since I was so far away. They were quick to respond to my multiple inquiries. Negotiated a price with them but ended up buying something else locally.

My truck has a great appearance, inside and out. It is a pleasure to drive; and rides and performs great. It is the best truck I've ever owned.

Thank you again David Cutts,you made my decision easy and took the pressure off me..More importantly the wife is very pleased.We will see you in 2years

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.

Billy was super helpful. Everyone at the dealership was friendly as well. Only took a star off because it’s apparent they like selling the service warranty, but I understand how sales work. I’ve gotten two cars here and I’m sure I’ll get more in the future!

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.

Andy was just so nice and attentive to work with. Very professional; answered all my questions and really went the "extra" mile to provide exceptional customer service. Thank you to everyone!!

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.

I will return. Best service department in Waukesha. And I have been to several of them.

This is the nicest truck I have ever owned. Lots of features. Takes a while to learn what all it does but a really enjoyable vehicle.

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

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.

My sales person, JJ Wilmer was very courteous. He answered all my concerns, showed me at least six vehicles. Answered all my questions about each to help me decide on one. He made the whole buying process pleasant.

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!!

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

There is no better dealership than Rosen Honda! We & our family will only purchase our Hondas from Rosen. From salesman Mario, honest & genuine, to service department (Kyle & staff), & most importantly, owner Jeff Rosen, truly hands on owner, it’s a well oiled operation. They truly seem to care about their customers!

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?

Marios was my sales person and was very attentive. Highly recommend the dealership. Very professional and would recommend.

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.

Jose was great! He helped us get a great car! He understood our concerns and what our budget was and worked with us every step of the way. 100% recommend him for sales :-)

2024 GMC sierra 1500 duramax 3.0 is great truck. Great ride and great MPG. 100% recommend to any prospective buyer. Love the truck and how it perform.

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!

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.

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.

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.

Just started looking for different car. No pressure. Let us look at our pace and we're available to answer questions as needed. Good experience.
