Great dealership. Easy going people, they take their time to explain everything you have questions about and try and help you anyway they can. Kevin was awesome to work with!

I Love our new GMC Terrain… We had an awesome experience buying our car. The car was better than what I thought it would be!! Inside, It has great space.

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 had many Jeeps, when they stopped making the Cherokee I was at a loss until I came upon the GMC Terrain and so happy I did. Great style, performance handles great, many exceptional features, I spend a lot of time driving and never feel like it is tiring, lots of room in cabin and the cargo area. I have a new favorite, and it is the Terrain

This dealership was great the hospitality was through the roof, though we didn't make a deal I would 100% comeback.

I’m 56 and I’ve mostly owned trucks in my life. Out of the few cars that I’ve owned this 26 terrain elevation edition is the best car that I’ve owned. It’s comfortable and expensive gets good gas mileage plenty of room inside well designedand GMC has been a reliable brand for me over the years. I do recommend this car.

Todd was very helpful and made sure my car was pulled inside when leaving as it was very slippery outside

This is a very beautifu vehicle, very dependable but the gas mileage could be better. With all of the new technology, it is somewhat difficult to remember all of the various control panel options. Also the owner’s manual is very skimpy.

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

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.

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!

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.

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

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

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.

I am very grateful and happy to Jamie who was the person who helped us and guided us from start to finish to find the right vehicle for my friend.

They make you very comfortable with the process of value of trade in to purchase. I recommend Palmen for any future vehicle purchases. I'm very pleased with them.

Expectations were set and met on a Saturday with college football on. Two separate seating areas in case you wanted the option to watch something else. There's also a kids' area if you have a little one who needs to be entertained for the time you're there.
