Great selection of cars.
Great selection of cars. I bought my Tesla at Affinity and couldn't be happier. After going to a few different places Affinity had the cleanest and by far the best service. I will be back again when the time comes.

Purchase of a certified Buick Regal
I live far from this dealership but they had exactly what I was looking for. The whole experience was very favorable . Everyone I has contact with was very professional and courteous. The salesman I worked with Joe Kendall was excellent. The day after the purchase I noticed that a light strip was missing on one of the outside mirrors. The service dept fixed it. In my opinion they are a top notch GM dealership . Keep up the good work😀

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!

I worked with Rocky and had an amazing experience.
I worked with Rocky and had an amazing experience. This was my first car purchase from a dealership of any sort so I was very nervous, but he was incredibly kind and helpful and explained everything I had questions on. He was very thorough and I felt super satisfied when I walked off the lot with my car. Cannot thank him enough! Same with Matt the financial adviser there, he was also incredibly thorough and kind and explained anything I had questions on! I highly recommend this dealership and these guys! They were amazing! :D
