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.

Great prices good service very polite and knowledgeable
Great prices good service very polite and knowledgeable staff. I bought a car from used car super store. After being tricked by lots of dealers and sales guys I was referred to them by a fiend of mine and I am glad I did go there and ended up buying a car. Very honest and straightforward sales staff.

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.

Life Savior - A heart felt THANK YOU
Based on my experience, I have to give five stars and double it to ten. What more can I ask? Very lucky! My first call was with the service manager Alberto. He explained the details of what to do in the situation like I was experiencing and Alberto, Nick and many others worked like a great team. They are polite, kind and they followed through every promise they made, charged me the minimally necessary, and even went ABOVE and BEYOND to reduce cost knowing what I have been through. Not only the new catalytic converter was restored, but I understood my car more, oil, fluid change, the car got a new life. I knew my car was happy there. Not only I am super grateful, but I know that God will bless their service, and each one of them for their kindness! Thank you! BTW, they provided great shuttle service at no charge, my car was super clean, the 13 year old battery was replaced, I truly appreciate the attention to detail. The car was there for 9 month due to the national back order, they took SUCH GREAT CARE for the car. Here is a bit more detail: My Prius's catalytic converter was stolen 9 month ago, since then my car has been through two Toyota dealerships. I called five. I had to move my car due to the dealership change stories after got me in or asking for excessive work, some suggested welding, it became confusing and exhausting for me physically and mentally having to move the car multiple times. So I just randomly search Toyota dealership and ended up calling Toyota on Western. The call with Alberto was short and sweet, about five minutes, I decided to move my car to their location. Glad I did! Alberto was straightforward, very educational and professional. It was from him, I finally understood, why welding the catalytic for the Prius converter is wrong, and I am all for doing the best for my car. I was uplifted, and relaxed after Alberto took my car in. He also move the car from time to time to keep the break in good shape, no amount of money or compliment can be exchanged with such genuine help and willingness to do good. I am smiling, and feeling very thankful!

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.
