2021 GLC300 4matic
I absolutely love this compact SUV! Coming from a Subaru Outback, this is light years above and beyond for same year. A quiet cabin is my top want for buying a car. This cabin is quiet and relaxing inside. I’m tall and there is plenty of room. The seats are incredible! Can’t wait to take it on the roads in winter.

Excellent service, very knowledgeable of any questions I may have. Always friendly and a pleasure when in the waiting area. Clean environment since I usually do work when I come in. Thank you to the Kia Team
Exceptional Comfort
I have had this vehicle for only one month so have not developed much experience with it. I did take it on a 1400 mile trip two days after purchase. It ran well, was very comfortable to drive, made for a very easy trip, was great on gas mileage, and it is very quiet inside the cabin. Seat comfort is exceptional and this, being our first experience with heated seats and steering wheel, was most enjoyable.

Nice surprise!
Everyone was nice, friendly and did the oil change in a short period of time. I am happy to trust that the work needed for my vehicle was done with the utmost professionalism. Especially pleased with surprise at the end. Thanks for another good experience. Would recommend this dealership. I will be moving and am disappointed that I will be too far away to continue servicing at this dealership.

I just bought a 2019 Mercedes-Benz CLS 53 AMG from
I just bought a 2019 Mercedes-Benz CLS 53 AMG from Chicago Auto Place. I'm out of state but deal was great. Took about 5 days to get delivered. Longer than i wanted but they delivered. Kept communications the entire time. Ricky was great. In the process i got worried and started researching. There are some people years ago that didn't review well. I really don't thinknthe deserve those reviews. After i got the car i asked the owner about them. He said they changed their business modelnto higher end cars with lower miles. And it has worked for them. I am 100% happy and have a stellar car. Inwould recommended whole-heartedly. They are in Chicago and i amnin Texas. Stressful buying online but they delivered on all cylinders.

Great Overall Experience
Was looking to purchase a specific vehicle from this dealership. The one I wanted had a pending sale. The sale was not finalized and the salesman I was working with called me inmediately to inform me. I think everything went pretty fast once at the dealership.
