Haggerty is great place to buy & service your car
From originally purchasing my car at Haggerty to having my car serviced at Haggerty, my experiences have all been positive. Everyone is friendly and answers all of my questions. Work is done well and on time.

A dealership you can trust
I was looking for a specific car that was at this CarMax. Problem was that I live in Minnesota, not Chicago and would have to traveling a great distance for a car I had not seen other than in pics, potentially risking wasting a great deal of time and money. I had to trust Jonathan, my salesman, to tell me the condition of the car where the pics could not. He was completely honest and the car was exactly what he said it was. Between Jonathan and Adam, the sales manager i was able to close the deal and drive back to home within an hour. I am completely pleased with the car and 100% satisfied with the dealership. I guess you can trust a car dealership. I did and they did not let me down. Thanks guys.
Great Buy!
This truck is amazing. Turning heads all over as we tour the area. Those riding with is also enjoy the comforts and safety features. Great Buy!

Buying my Camaro from Castle Chevrolet in McHenry was an
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.

Fair Oaks was the only LIncoln dealer that had (in transit) the exact 2025 Lincoln Aviator model and color scheme we were looking for. We were able to connect with them online and make a good deal on the purchase without having to make the extensive drive to the dealership. Krystal (internet sales manager) was great to work with. She handed us off to Eddie to complete the paperwork. All documents were completed online in the comfort of our home, and Eddie delivered the vehicle to us at home the day it arrived. Eddie continued to follow up after the sale to make sure we were satisfied and answer any questions we had about the vehicle. I can highly recommend this dealership.
