I have never been happier since I bought my Buick at The dealership in Barrington Illinois Tim McIntyre was our salesman and Dave the manager Patrick in the finance department Went far above any expectation I had for any dealership we had been looking for a car for several months I’ve never bought a Buick It truly is The best car I have ever owned This dealership Made this purchase so enjoyable I recommend them to oeveryone

Jim Sprandel sevice mgr. very nice man and also explains everything to you clearly.The rest of the staff was also very pleasant. I would give this dealership 10 stars if I could. My car was washed for me and I needed it considering it was a cold winter day.

Overall, the service was professional, informative and understandable from beginning to end. I came in explaining what I was looking for and that’s how it was through the process.

Team was Great James and Financing department went above and beyond for us

Excellent customer service and great to work with! They even delivered my vehicle to me. Nick in sales is the best from start to finish!

Bill was fantastic to work with! Whole process took only a couple of hours and everyone was very helpful. Pricing was transparent and they worked with me to get me best interest rate possible.

Kevin was very helpful and gave me a deal on the Sierra 1500 that I couldn't refuse 10 out of 10

Mike R was our sales consultant. He did a terrific job explaining everything in addition to helping us with creative financing. Kudos to the dealership!

The Marquardt experience was fantastic. Our sales rep, Fiona, was very knowledgeable and provided world class service. If you are considering a vehicle from this dealership, we highly recommend her.

GREAT Jamie was awesome He listened to my wants and need Best dealership experience in 7 New vehicle experiences

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.

I have to say that Ryan and the staff at Napleton sure know what they are doing. They were quick to answer any questions I had and took away the fear of buying a car! They were friendly and knowledgeable and NOT pushy like most car salesmen. I walked away with a vehicle that I love and a great experience!! Thank you Ryan for all your help!!

We purchased a used car from Robert and he was extremely respectful and went out of his way to be helpful. We needed to get a car trailer to get the car back to Louisville Kentucky. He was able to find one and reserve it for us. Everyone at the dealership was very nice and helpful. We enjoyed dealing with everyone. We will always remember the great service and friendly staff. We will remember them if we make any future car purchases.

Kim was incredible in helping me get my repairs covered by my extended warranty! Details of service were provided and car was ready when needed.

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

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.

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.

The Advisor Tony and mechanic Technician Klaus are the best. I give both of them 10 Stars for such great service. These two both strive to achieve the performance level of Excellence in their jobs everyday. Thank you for such great work

Great service as always Mike really help us every time we need a car he understands why you looking and what it fits you better.

I haven't had time to get together with the dealership I am hoping to go in this weekend.
