Used GMC Yukon XL for sale near Union, IL under $50,000

Great service! Mark was awesome. My appointment ended earlier than expected too. Plus a comfortable waiting area with coffee!

This is a luxury suv with plenty of room. I'm still learning the features. It is a smooth ride with a great interior. Great for towing a popup camper.

Super honest deal. Used car as advertised, no surprises, no pressure. They detailed it for us while we did the paperwork.

Read many reviews and researched this vehicle and that helped me decide on this vehicle. Traded in a older suburban for this updated Yukon. Look forward to driving it.

Thank you to the service team for your getting me all set for my roadtrip!

Perfect . If you want to get good emotions then you need this GMC Yukon Denali XL . L M k if you have any questions please

The dealership had a great selection of quality used cars, all well-maintained and reasonably priced. I appreciated their transparency and honesty throughout the process, including providing detailed vehicle history reports. The financing process was also seamless, offering several options and explaining everything clearly. I left feeling confident and satisfied with my purchase. Overall, I highly recommend Affinity Auto Sales to anyone looking for a reliable used car and a pleasant buying experience. Thank you to the entire team for making this such a positive experience!

Vehicle is very nice and has all the bells and whistles. I bought it to pull a 26 ft Airstream and it does the job but not great, could use more power for towing. It is difficult now to find a vehicle to pull a large trailer. I didn't want a pickup because I haul a large dog that takes up the entire back seat. I wish they still made the 3 quarter ton Yukon with the larger motor like I used to have. You could haul anything with it. The Yukon XL with the 6.2 motor just barely does the job.

I really appreciate the straight-forward buying process I found at Napleton Schaumburg GMC. Thank you to Yiannis for answering all my questions! Best- Mark

great car has everything and then some. lots of seats and 2nd row heated is cool. it could use a little more under storage in the rear compartment and a cover

This meets all of my needs so far, I expect it will continue to do so, and will last me a long time. I love it. 1 owner, perfect interior, no accidents, no scratches, no dents.

Great people. Great service. Highly recommend Erick and team. They will give you a solid deal

So far so good! Beautiful ride and very comfortable. Love the smooth ride. Will be perfect for traveling with our parents, children and grandchildren. Thanks!

Darien was professional, knowledgeable and engaged in the entire process. Darien even agreed to come in on his day off to meet with us. At Biggers, there is no pressure and no hidden fees - a welcome change from other dealers. Joe made sure we had answers to our financing questions. Thanks!

I love my new yukon xl very nice and comfy, ride is supper smooth. The truck is big for my 3 fur babys with rear ac wich is nice for them on our road trips

Amazing place to buy a used vehicle, I have bought 2 vehicles from here for my daughters. First on 7 months ago and the second 2 weeks ago. Both vehicles are great.

My favorite car I have ever owned. I've had cars, trucks and a couple of small suv type vehicles. I thought it would feel like a big blazer. And boy oh boy was I wrong. I bought it ar 180,000 miles and it drives like a dream. All the power I could ever ask for. A bigger engine than my camaro had and almost as fast. My kids love it, I love it the wife hates the mpg but if we have a snow storm we take the denali, when we have the 4 kids me and mom and we can still fit another adult and any and all luggage. What is there to complain about. It's reliable and when you expect the instrument cluster panel to be wonky from bad wiring. Well it's nothing that stops me from getting where I want to go everytime. I love the vehicle and hope to keep it for a very long time.

Great family owned dealer. Easy to deal with and you can actually talk to someone that knows what they are talking about.

This Yukon XL has exceeded our expectations. We upgraded from a 2014 XL and it's like apples and oranges. From a size standpoint, the new design allows my 6'6 son to sit in the 3rd row. Not possible on the 2014 xl. Also, they have upgraded all of the finishes and with the new 10 speed tranny the XL drives and feels amazing. We also opted for the 3.0 diesel as that's what was available. We didn't even test drive one as they are hard to find - but man are we happy with the engine, gas mileage, and just how quiet it is. In city driving we're getting about 22 mpg, and then on highway expect to get about 27. Safety features and heads up display all work great. And, the sunroof thing is amazingly huge. Well done GMC and I highly recommend the Yukon XL to anyone that needs to move people in comfort. :)

Buying my Camaro from Castle Chevrolet in McHenry was an outstanding experience from start to finish. I worked with Eric Loredo, who set the tone by doing a full virtual walk around and video of the car before I arrived, answering all my questions in real time. When my wife and I landed at ORD, the car was spotless and ready to go. Finance Manager Mike Lazzara had all documents sent ahead so I could DocuSign, making the delivery quick and smooth. Sales Manager Matt Knudson, GSM Jerry Spanier, and Andrew Sytsma (who wasn’t my salesman but still took time to chat and share product knowledge) all played a part in making this one of the easiest purchases I’ve ever had. The team knew my previous car was totaled in a tornado, and they went above and beyond to make this out-of-state transaction simple and stress-free. Eric and the entire Castle team reminded me that buying a car doesn’t have to be a battle. I would absolutely buy from them again.

Love the truck, lots of bells and whistles, smooth ride, satin Steele is a beautiful color. The Denali has lots of space for my four boys.

Great selection of cars. I bought my Tesla at Affinity and couldn't be happier. After going to a few different places Affinity had the cleanest and by far the best service. I will be back again when the time comes.

I just bought my 2017 corvette grand sport two weeks ago. I flew in from New York. I can’t say enough good things about the process. We worked with Armin, he was top notch. He made every aspect about buying this car seamless and easy. He even arranged an Uber to pick me up from the airport to bring me right to the dealership. We just adore our new car. It’s perfect!! A million thanks 🙂 Joe and Denise

Great vehicle to drive and be a passenger in. Room galore for transporting people and gear. The car is luxurious in the way it looks and drives. The 4WD was outstanding in Denver's recent major snow event.

Very smooth experience. Seann is an excellent young salesman. Darien will do anything to work with you. Erick, the manager is very accommodating. A++++ dealership.

Very good repairs were done correctly and a timely manner

I love the Yukon. It needs a few censors changed out but it drives so smooth. Very glad we made the choice to purchase it

Service is great and friendly and they will do everything they can to make sure you get your car in and out no problem. They’re awesome! -jimmy sands

This car is so luxurious, and it is a family hauler! The thing is like a Sherman tank met a luxury hotel and had a baby. I love the vehicle.

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 brought my vehicle in for every oil change I have needed. Always courteous and professional, my car gets a diagnostic check every time and is freshly washed. I like that the Service Department send out coupons, and making an appointment is easy online or with a phone call.

My salesman Esad was great. He was very knowledgeable. Everyone was very friendly and helpful.

On my 7th one. That should say it all. Quality crafted, full of great features, super smooth ride and plenty of room for up to 8 people plus a ton of gear.

Have trusted this dealership for over 25 years. I wouldn’t think of bringing my 2 Buicks anywhere else. They only do necessary repairs which I appreciate and will give you a timeline as to what to expect down the road when it comes to doing work. They value you as a customer and do everything they can to help you in all aspects serving you.
