Contacted them over email since I was so far away. They were quick to respond to my multiple inquiries. Negotiated a price with them but ended up buying something else locally.

My son and I recently purchased a 2017 Kia Forte at Lynch
My son and I recently purchased a 2017 Kia Forte at Lynch Chevrolet. It was an awesome experience. We were greeted warmly by our salesperson Kurt Martiny and he listened carefully to our needs. Kurt skillfully connected us to the best car to suit our budget and needs. Kurt offered to keep us comfortable while we awaited the process. The showroom was spotless, bathrooms clean and the coffee was very good. It was an over all wonderful experience.

Sergio and Carmax were excellent!
I would highly recommend Carmax Kenosha. We setup an appt and test drive on their website, and Sergio reached out right away and put the vehicle on hold for us. When we arrived the car was ready for us to test drive, and while we were test driving they looked over our current trade in. We got a fair value on our trade in, a fair price on our new vehicle, and we were in and out in under 2 hours. Thanks Carmax and Sergio for the awesome experience!!

I had a great experience today car shopping Honda
I had a great experience today car shopping Honda Libertyville. The manger Fareed gave me an amazing deal. My salesperson Davi was very knowledgeable and he helped to guide me through my car buying experience. He answered all my questions and eased my concerns. If you are in the market for a new car, give Honda Libertyville a shot.

great service!
I was on the market for buying a new car. I travel to work pretty far everyday so I needed something that was good on gas,low mileage, and reasonably priced. I was so amazed by how helpful the car sales associate Mourice was. He was very friendly and had my best interest. He wanted to get me the best deal possible for my money. He knew about all the cars I asked about on the lot and showed me cars that had the features I was looking for. I would highly recommend him to anyone looking to buy a car!He made my finding a new car experience less stressful!! I am so pleased with the car I bought!

Had an AWESOME sales experience when we purchased our 2023 Terrain. Stephan took great care of us and was very knowledgeable. Robert & Ryan in the finance department were easy to deal with and very responsive to what we were looking for. Did not feel pressured at all. Overall a great interaction with Kunes Lake Geneva.
