New and used 2025 Hyundai SONATA for sale near Mount Prospect, IL

I just purchased a car from Castle Hyundai of Oak Lawn, and I couldn’t be more grateful for the experience. From start to finish, the team showed true professionalism, care, and integrity—qualities that can be hard to come by in the car-buying world. Now I truly understand what they mean when they say “Drive Happy!” Jim (Sales Manager), Nick (Sales Consultant), Brennan (Internet Representative), and John (Finance Manager) were an absolute pleasure to work with. They went above and beyond to make sure I felt informed, respected, and supported throughout the process. They were transparent, never pushy, and always willing to answer my (many!) questions with patience and honesty. It was clear that they genuinely cared—about the car, the deal, and most importantly, about me as a customer. They didn’t just meet expectations - they exceeded them. The entire process was smooth, respectful, and even enjoyable. These are good people who take pride in doing right by others. Thank you to everyone at Castle Hyundai of Oak Lawn—you didn’t just help me get a great car, you made the whole experience one to remember. You went the extra mile (pun absolutely intended) and because of you, I now Drive Happy!

We purchased a 2025 Sonata from Freehold Hyundai. Very happy with our decision- great car and rides smoothly. Nice design as well, and very quiet while driving.

My rear bumper is damaged with my 2002 silver Honda Accord. I’m thinking about selling my car and buying myself a new car.

After having dealt with a dealer who did every stereotypical salesperson trick ("Sign here to show my boss you're serious") it was great to deal with Hunter who could not have been more helpful (look him up if you want a salesperson who legitimately wants you to be happy with the process, not just make a sale). Everyone involved was great. While they didn't have what I was looking for, I was trying any way to throw them my business--they're that good. Maybe next time...

I would like to focus my review on one particular part of my experience. Two weeks ago, after a long look at new car options, I decided to buy out the lease and purchase the 2022 Rogue I'd been driving. I wanted to make sure my car was in new car shape so I brought it to Berman for a certification inspection. I've previously not felt important bringing my car for service there, and generally my service history has felt like I'm at the mercy of the dealer or service department. However, on this occasion, I received the best customer service I've ever received in 35+ years of bringing my car to a service department. Turns out, the Best Service Manager in the car industry is at Berman, and her name is Katie Udelhoven! I'm a very tough customer, quick with numbers, and very demanding. Katie not only went out of her way making phone calls to see if she could save me money (seeking to find and use as much coverage under my lease agreement to save me as much money as possible), but she explained in great detail what every issue meant to my safe driving experience, and had feeling confident that she and Berman were acting in my very best interests! Katie is the most knowledgeable service manager I've ever encountered as well. She responded immediately with credible information to every concern I posed. If I had a dealer ship myself, I would want Katie Udelhoven to be one of my first hires, and pay her at the very highest level of the Service Manager pay scale in the United States. Having worked with every level of Berman staff in this process, I am slighting no one to say ...Katie Udelhoven is the single most valuable asset within the walls of Berman Nissan, including the cars and the highest levels of your organization, she does a second to none job of making sure each customer, I'm guessing at least 40 each week, leaves happy!

Such a good experience, from introduction to purchase. They pretty much accomodated all my needs and they do all this with no "dealer fees". I would buy from them again if I can.
