Thanks to the professional staff at Napleton Buick GMC in Crystal Lake! Especially Ryan and Erick!
Eric and Freddi and Napleton were very helpful throughout the entire process! We love our new car
Everyone was nice. They worked with me on my situation and I was able to get a very nice ride. Definitely would recommend 👍
Mike Bell did a wonderful job in presenting all the options available. He made the experience very easy and pleasurable. Great employee!
I worked with Rodrigo at the dealership, and I couldn't have been taken care of better, Rodrigo was very welcoming and helpful. I walked out with a brand new car and couldn't be happier. I definitely recommended this dealership and Rodrigo.
Fast and courteous service Very pleased
Mike Bell provided great service thru the sales process and the finance team worked to get me competitive rates that beat my own credit union's. Thanks everyone
Perfect experience. Made purchasing an ease. Would absolutely recommend and use again in the future
My experience at Napleton Buick was wonderful. Rodrigo was the one who sold us a 2018 Enclave. He was extremely polite and personable. I felt comfortable being there and didn't feel pressured into making a deal. So yes, I would recommend this place!
Thanks to Erick, darian, freddi, christian for such fast and kind sales! Helped us find exactly what we're looking for!
I have been buying cars for 50 years. Maybe the best car buying experience ever. No pressure , low price, great service etc. Service manager came out to meet me and discuss the new truck. Nick the sales guy very knowledgeable and great demo on how everything worked. I will be back and feel good about the experience!
Great experience buying my new truck from Napleton in Crystal Lake. Mike Bell did a great job and he was very honest and easy to work with.
Shawn did great on his first day
From start to finish, the entire staff made sure the buying process was as seamless as possible. I went in knowing what I wanted and left with exactly that and then some! Ryan was great and definitely took the time to ensure the car I chose was exactly what I wanted.
Our salesman, Yiannis, was a pleasure to deal with. Would not hesitate to work with this dealer again in the future.
I highly recommend purchasing a car here! Rodrigo was super helpful!
Rodrigo was the best! Worked out a great deal on a 2025 Buick Envision Avenir! Great service over all!
Came to but a car for my wife and it was amazing service told them we had a dead line and they got us out by that time will always recommend them to everyone
Great service. Great personality Thank Mike for your service
I looked at an Equinox, I called and got a price. I drove 1hr 20 minutes, got there at 7:20pm, was greeted by Eric the manager and salesman Kevin. The car was ready and was in perfect condition, we agreed on a price that night and since it was late a handshake was all that closed the deal. Friday I had to work but they offered to deliver car on Saturday. The car arrived on time and they installed new tires as part of the deal. Eric and Kevin went out of their way to make sure the car was perfect for my daughter. There was another person involved Marty Napleton who didn't have the car I was looking for but called Eric and asked him to help me with the sale at a different dealership. This by far was the best car buying experience I ever had. I look at Marty's or Eric's dealership for my next car. No hidden fees offered services. Gave me the price quoted and I can't say enough about Napleton Auto Group. They set a standard that will be tough to beat. Thanks again, Steve
I called Jen from the highway , told her the problem i was having and that i was on the highway in Chicago. She told me to try and get it here as soon and safe as I could. I got my car there and explained all the problems to her. She wrote everything up and told me they would get back to me as soon as they did all there resting. They called me the next day and told me everything they found. They called my insurance company and got back to me with what was covered. I picked up my car the next morning. Jen is the best customer service person. Thank you and your team Jen for getting me in and getting my car fixed in a timely manner.
First time buyer with Napelton-Crystal Lake and was very satisfied with experience. They were very helpfull in securing a printed owners manual, for me. Cannot believe GM has stopped supplying owners manual in new cars, that are loaded with high tech features.
Thank you. Christian, Darien, Freddy.
In and out quick service, The help from Samara , Erick and Mike was excellent, definitely recommend this dealer to purchase your first, second or third car.
I got Good attention from Freddy
