Used GMC cars for sale near Williams Bay, WI under $4,000,000

I've been looking at Aviators since 2021. After getting screwed around by several other dealers, one phone call to John Newman and I had my Aviator within 2 months.

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.

Absolutely amazing service by Josh and the Kunes team they fought tooth and nail to get me into my amazing new 2019 chevy cruse rs

Great staff and very good deals on new vehicles. Quick, friendly and very helpful. I would recommend if your looking for a great deal check with these guys first. They will get you that Great deal others can't.

I have enjoyed my vehicle. It is comfortable and drives very well. I like the color also. It is very roomy, takes off fast and the safety features are very beneficial.

My sales person at Castle Chevrolet was Tony Twall. He was awesome to work with. He answered all my questions and was very knowledgeable. I have to say that this was the best vehicle buying experience I have ever had. My next purchase will be with the Castle dealership in McHenry IL and I will ask for Tony to be my sales person.

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?

Great place to buy a car very friendly would highly recommend them everyone was very helpful and gave us a good price on a vehicle

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 have purchased many trucks over the last 35 years. I have never had a purchase go as smoothly and efficiently as this one! Kunes is good! Very professional, responsive, polite, fair and communicative. Great trade in value on my truck and very fair price on the new one. Love it!!! Thanks to Dan and all his effort.

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.

Very professional and pleasant people I dealt with in my purchase and service work of my vehicle. Would not hesitate to buy another vehicle or have them perform service work.

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.

Out in 45 minutes. Great clean service center. Service techs, Bob & Jon, are polite and professional. Car was parked right outside the entrance. Thank you for always providing a good experience. Jim Fus

Nice styling,interior has a new design dash which is beautiful and convenient,safety features and cameras are great and easy to used and the active cruise is awesome.

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

Matt in sales is extremely professional. His knowledge of the vehicle was obvious. He throughly explained the car's features with me. I'm glad he was my sales representative with the Castle Subaru dealership.

Always smooth and easy-going at Lynch. They take great care of us! Would highly recommend anyone in the market for a new or pre-owned vehicle.

Fast, courteous, personable, professional, a great experience— thx! Will recommend to others! Work was excellent.

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.

I recently had to bring my used car in for a vibrating brake pedal, and the service I received was outstanding. The experience was impressive from the moment I drove in; a machine automatically checked my car's alignment on the way into the service bay, which is very impressive. -- What really set them apart was the customer service. Not only did they provide a convenient shuttle to and from work, but they were also completely transparent and honest about the repair. Instead of pushing for the more expensive option, they suggested I resurface the rotors, which saved me money. -- That kind of integrity is few and far between; it earned my complete trust. I had a fantastic experience, highly recommended!

The Yukon checked all of my needs, I have plenty of room for my children and my Great Danes. I enjoy driving the Yukon and how it handles, overall love this vehicle!

Easy purchase experience, would recommend to anyone looking for a new car. Everyone there was friendly and made the whole process as smooth as possible

Wonderful experience! Bought my car from Cody and he was absolutely amazing! We loved his attitude to help us get a good deal, he was truthful and straightforward! If I could give this place and my experience more than 5 stars, I would! Thanks again Cody! You really made this process easy and quick!

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!

Good service thank you. Easy drop off and pick up. Good service thank you. Easy drop off and pick up. Thank you again. Good service thank you. Easy drop off and pick up.

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

Excellent Vehicle Buying Experience!!! A very relaxed environment with a no pressure. My salesman Anthony Castalado, his Sales Manager Bob (can’t remember his last name) and Heinrich in the finance office were great. I drove home in my new used vehicle with a smile!!! Love my new to me 2022 Ford Explorer xx-Line!!!

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.

Janel and Dave very helpful. I wanted a jeep. I saw one online so wanted to check it out it was missing a few things I really wanted. Janel went Dave and talking Dave said there was one that just came in the night before. I took it on a test drive yes that was the one. Went back in Dave was doing magic with numbers found the one so I bought my jeep. Only have great things to say. I would definitely tell my friends to come her. This has been the most comfortable atmosphere. Thank you Janel and Dave

This Yukon has all the bells and whistles. It is a joy to drive, the drivers area is like a cockpit with everything at your fingertips.

Lamia was Amazing!! She was so friendly, personable and I walked out with the car I wanted!!!

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.

Andrew Doyle at this dealership was amazing to work with. He was soft spoken, detailed yet concise. He was influential in making a deposit for a purchase. I had to pull out later for other reasons. But I give high regards to Andrew’s work.

This car is a fabulous car for family and traveling. It is roomy, has capacity for kids and sports gear, and is safe. I have been rear ended twice in a Yukon and there was minimal damage to the Yukon and extensive damage to the other vehicles.
