Great purchase experience
The Team that my husband and I worked with Dillon, Tim & Dan, were all very helpful and courteous. We had a certain price point and they managed to get us very close to where we needed to be AND we got the car we really wanted. Buying process was seamless, communication was great, and customer service was wonderful. This was our second purchase with Haggerty and we highly recommend!! Thank you
Great Buy!

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.

Multiple vehicles purchased and ZERO issues. A+
Great selection and good prices. I needed a van for my business and I bought 4 from them out of state. When I picked them up they were ex aptly as described. And all.of them made the 550 mile trip back no problem. Very satisfied and they took care of me like family. I asked them to please make sure my crew would make the the trip back without breaking down and they did. Will be buying more vans for my fleet and this time I will have them ship them since I can trust them after this experience. Out of 20 years in business and buying vehicles they have been the best dealer I have dealt with so far

recently purchased a vehicle from Old Orchard Nissan, and I couldn’t be more satisfied with the entire experience. From the moment I walked in, the staff was welcoming, professional, and genuinely helpful — no pressure, just honest service. My salesperson, Jason Chu, was knowledgeable, patient, and took the time to answer all my questions. They helped me find the perfect car for my needs and made the process feel smooth and stress-free. The finance team also did a great job explaining everything clearly and worked to get me a great deal. The vehicle was clean, in excellent condition, and exactly as described. I truly appreciate the transparency, integrity, and care that went into every step of the process. Highly recommend Old Orchard Nissan to anyone looking for a reliable vehicle and top-notch customer service. I’ll definitely be back when it’s time for my next car!
