ABDUL was VERY helpful to us within moments of us walking
ABDUL was VERY helpful to us within moments of us walking through the doors at 9:00 a.m. Saturday morning. He facilitated our selection process from our initial inquiry to our final selection. He exhibited good salesmanship, active listening, leaning in, gaining rapport, relevant & meaningful story-telling, and carefully wove the common thread of love for family into the selling process...we even found common ground about cultural things that we found funny...The skills he exhibited and values we shared seem to be disappearing in this new economy. We LOVED Lewis. Lewis knows every aspect of financing inside and out. He's so smooth. He respects a "NO" then remains conversational and low-key until he gets to "YES". Smooth! Top Performer's Sales Training at its best! We connected immediately and beyond just an occasional LOL, we Laughed Out Loud - LOUD and OFTEN...By the time we left, we were tired, hungry, but IMMENSELY pleased with all of the contractual guarantees, servicing/warranty explanations, being financed by the company of our choice - and our friendship with Lewis. You'll LOVE his iconic signature!
The features are amazing,stylish .
Great driving comfort,loaded with features. Safety is definitely a priority with the MB engineering . I have leased a total of 4 Mercedes and totally satisfied with every single one.

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.
Most incredible car I’ve ever owned.
This is my second Mercedes-Benz. It’s absolutely the most incredible car I’ve ever owned. I was blessed to be able to custom order this car to have everything I wanted and more inside and out! It literally came straight from Germany to the dealership for me. It drives like a dream. It’s absolutely gorgeous. The technology inside is so amazing! It can drive economically. It can drive more sporty if you want it to. It has so many options and settings for drivers of all kinds. Needless to say, it’s pure luxury inside. You’ll feel incredibly spoiled!

Go see Maurice....he has SUPER POWERS!
If Maurice were a super hero, his super power would be making great deals happen. He was friendly, helpful, informed (and don't even get me started on his accent)! I never once felt pushed or pressured. I am 100% convinced that the great deal I got would not have happened without Maurice. Aside from that, it is a rare salesman who makes you feel like he is really ON YOUR SIDE. I'll keep it short - he's earned my trust and that is the ultimate compliment I can give.
Haven't put many miles on due to snow and ice.
Not enough miles driven to fairly evaluate but look forward to driving when weather is better. I have high expectations! I'll need time to get used to the console controls.

Service
Since moving out to the NW area we have been going to Bigger Chevrolet for service. We only had an issue one time and it was handled immediately by the owner. For me that says a lot so I?ll be a constant customer. When ready to upgrade my vehicle this is where I?ll go because if you have a good service department and the owner responds to any issues, no matter how small then it?s an honest dealership worthy of my patronage. Thank you.

Buying my Camaro from Castle Chevrolet in McHenry was an
Buying my Camaro from Castle Chevrolet in McHenry was an outstanding experience from start to finish. I worked with Eric Loredo, who set the tone by doing a full virtual walk around and video of the car before I arrived, answering all my questions in real time. When my wife and I landed at ORD, the car was spotless and ready to go. Finance Manager Mike Lazzara had all documents sent ahead so I could DocuSign, making the delivery quick and smooth. Sales Manager Matt Knudson, GSM Jerry Spanier, and Andrew Sytsma (who wasn’t my salesman but still took time to chat and share product knowledge) all played a part in making this one of the easiest purchases I’ve ever had. The team knew my previous car was totaled in a tornado, and they went above and beyond to make this out-of-state transaction simple and stress-free. Eric and the entire Castle team reminded me that buying a car doesn’t have to be a battle. I would absolutely buy from them again.
