Ernie was a great salesman he walks you through eve step of the process

Alex is the man to see he knows his vehicles. Easy to talk to great customer service, he finds the vehicle you need. Alex help us in every aspect. Would highly recommend this dealership and recommend you all to see Alex.

Made a online appointment came in and they did a oil change and tire rotation. Happy with the service.

I had major work done on my car and I couldn?t be happier with the turnout. I had my transmission replaced along with a couple other issues on my 2017 vehicle. It took a while for the entire thing to get completed, but I was given status updates throughout the process. I picked up my vehicle late last night (5:45 pm). I was surprised the service manager was still there and he took the time to go over everything that had been done to my vehicle. The total price was slightly lower than what I was I was told it would be at the start. I was very happy and wasn?t expecting that. My car is driving great today and so far I?m extremely happy with the result from my service experience. I?m very appreciative of the help I was given and the customer service I received. Thank you Justin and everyone who worked on my car. ?

My first experience at this dealership will definitely bring me back. We are so happy with our purchased! We had Alex Alverio from Sales, he was very professional & helpful, has awesome customer service & we highly recommend Alex. Thank you so much and keep it up!

I purchased a 2023 Genesis Gv70 Form Napleton Downtown. I ordered the vehicle and it arrived months later. The whole process was seamless. I got the exact deal I wanted.

Highly recommend. Greeted us with a big smile on his face. Thank you Daniel Rico for the Buick.

alex gave me a great deal on our new buick..... thank you so much alex.

The sales staff is incredibly helpful but there’s one guy who stood out to me he was tall had curly hair & a beard. I don’t remember his name but I heard someone calling him Izzy. He was very respectful and you could tell he has a strong work ethic, that guy definitely deserves a promotion. I always see him working so hard at the dealership.

Anthony greeted me in the parking lot and was friendly and professional. He quickly brought the car out that I wanted to see. Negotiations were very fair and the paperwork was done in a timely maner. I love my new/pre-owned HyundaiTucson. Thank you Anthony and the team! I'll see you again when I need my next vehicle.

Daniel Rico is the man. Thank you very much Daniel for allowing us to drive couple cars made it easy for me and my family

I want to give a 5 star shoutout and big thank you to Raphael Ebisi and the folks at Napleton Downtown Chicago. Our experience here was best in class for communication, test drive, and the entire sales process. Raphael was an amazing host to us and it was a pleasure working with you. We found our perfect EV car for a unbeatable price and want to thank you. If you are shopping for a car, you'll be taken care of here.

Juan was excellent to work with, we quickly agreed on a price, the vehicle was cleaned and ready to go by the time the paperwork was complete. Highly recommend.

Second car I purchased from castle gmc our sales person was Nubia /great experience every time helpful and always greats us as family highly recommend castle gmc Nubia and Brandon will take very good care of you . 👍🏻

Team was Great James and Financing department went above and beyond for us

I live far from this dealership but they had exactly what I was looking for. The whole experience was very favorable . Everyone I has contact with was very professional and courteous. The salesman I worked with Joe Kendall was excellent. The day after the purchase I noticed that a light strip was missing on one of the outside mirrors. The service dept fixed it. In my opinion they are a top notch GM dealership . Keep up the good work😀

I have worked with Dan Salisbury for years in regard to leasing various cars. Dan works very hard to find what I am looking for within the payment range I need. Dan never makes me feel bad for additional requests or continued questions. If there are any problems they are quickly resolved. During this last lease I had pleasure of also working with Alfonso Gomez. He was very quick at resolving small issue that I had immediately. Jason Garon in the service department is always amazing about getting my car for any oil changes or needed work. I am happy to recommend this team to others.

Great Cars and also good service. Vincent Vega was very helpful thank you Vincent for all your help. This is our third car from Castle Buick GMC. We loved thank you .!

I haven't had time to get together with the dealership I am hoping to go in this weekend.

Best experience I've had when purchasing a vehicle. Everything was handled quicky and professionally with no pressure to consider anything other than what I had asked for. I was completely satisfied and would recommend this dealer and my sales associate Larry.
