New and used 2026 GMC Sierra 1500 Elevation trucks for sale near Lake Forest, IL

Chris Lahey was an exceptional person to deal with and got us the car of our dreams!

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

I had a great experience purchasing my truck with Jamie Liszka as my sales consultant. Jamie was not pushy at all and truly allowed me to make my decision on my own terms. They were very transparent with all the information provided and took the time to address and respect my concerns throughout the process. The entire experience was quick, easy, and stress-free, which made buying a truck much more enjoyable than expected. I would absolutely recommend Jamie to anyone looking to purchase a vehicle, and I would definitely go back again for a future car purchase.

A little expensive, but comfortable, quiet, smooth ride. Great performance out of the 6.2L and better than expected fuel economy in the low 20s. Outstanding interior and good looking exterior, especially in the Downpour Metallic color. I don’t have 700 miles on it yet and have owned it for 3 weeks. Therefore, I can’t pass judgement yet on the reliability, but so far I am very satisfied. This replaced an 8 year old Ford F150 that served me quite well with only a couple of issues in the 100,000 plus miles.

I have worked with Dan Salisbury for years in regard to leasing various cars. Dan works very hard to find what I am looking for within the payment range I need. Dan never makes me feel bad for additional requests or continued questions. If there are any problems they are quickly resolved. During this last lease I had pleasure of also working with Alfonso Gomez. He was very quick at resolving small issue that I had immediately. Jason Garon in the service department is always amazing about getting my car for any oil changes or needed work. I am happy to recommend this team to others.

It was such a good truck honstly the greatest thing I have ever drove in my entire life I am so happy that I have been blessed with this being my first ever car

Most pleasant waiting room anywhere and the friendliest service people.The mechanics always attempt to fix problems before they start. Also wait time ia always fair.

I brought my car in for an oil change and multi point inspection. the inspection dealed that I a front brake issue. Mike, the employee I dealt with describe the issue and what it would take to repair it and how long I would have to wait he offered free transportation home if I wanted. because of the distance that I would have to travel there and back to home, I opted to delight the two hours in the lounge. I had coffee and water and I was fine. Mike came in several times to talk about the repair. He also said he had a rebate coupon I could use and he pointed out. I had points in my Buick awards account that I could convert to dollars to pay for the repair. That was very good service save me money and the car is running fine

Chris does an outstanding job every time I visit. He is very accommodating and always aware of my needs and my time. Only place I service all my vehicles (3) and drive 30 minutes even though there are 2 Chevy dealers much closer.

We had an incredibly smooth and pleasant experience at this dealership from beginning to end. The entire process was seamless from start to finish. Every staff member we interacted with was helpful, courteous and professional. Buying a vehicle from Seann Omara was particularly wonderful— he is knowledgeable, helpful, and genuinely committed to making sure we got the best deal possible. We left very pleased and would happily recommend Napleton Buick GMC to others!

As always, service and service reps were great-wonderful dealership and service department?have purchased cars from dealer for many, many years and will continue to do so.

Elliott was incredibly helpful. He had patience and don’t oversell. This allowed us to find the truck that we wanted vs feeling like we were pushed to make a decision. Would buy from Elliott again.

My service advisor, Michael, did a great job of communicating the progress of my service appointment. Not all the necessary parts were in stock after the diagnosis, but he kept me apprised of the status of their arrival and made sure I had a loaner when they came in. The technicians did a great job and returned my vehicle in great condition.
