Great Business !!
Bought a 2009 BMW 3 Series 6 Months ago and wanted to review after I had the car for awhile. I wasn't sure buying from a smaller dealer, but everything worked out and the car is still running great. I would definitely recommend buying from this dealer. Thank You Max!
Great car. Comfortable to drive long distances.
Very comfortable and reliable car. Great for road trips or around town. comfortable to drive and grab gas mileage. one of the best cars I have owned.

⭐️⭐️⭐️⭐️⭐️ 5 stars all the way for Quick Sales!
⭐️⭐️⭐️⭐️⭐️ 5 stars all the way for Quick Sales! If you’re looking for a dealership that actually stands by their word, look no further. I recently bought a 2014 Toyota Prius from Quick Sales, and from start to finish, the experience was top-notch. Ralph, the manager, is the kind of guy you hope to deal with when making a big purchase. He promised to replace the missing headrests on my car—and not only did he follow through, he went above and beyond by also sending a crucial part needed for my airbags. That level of integrity and follow-through is rare in the auto sales world. The transaction was smooth, the communication was clear, and Ralph made sure I felt confident and cared for even after the sale. It’s not just about selling cars at Quick Sales—it’s about building trust. I’m beyond satisfied with my purchase and the service I received. If you’re on the fence about where to go, let me save you the trouble: Quick Sales is the real deal. Five stars all the way!
My second A6
My A6 2.0 quatro has 110k miles. Still looks great. Have gotten 34.5 mpg on open highways in Pa. Comfortable ride. Leather seats are holding up. This is my second A6.

Car Castle is amazing
The staff is amazing and very helpful! We will be back! The car has been great and very clean inside and out. We are very happy with the purchase.
Lovely car in excellent condition 110,000 genuine
I find this car a joy to drive 14 yrs old and still looks very good (classy) 6 speed box manual and 4 X 4 I have driven the car for 5 years maintenance could be expensive but I buy my spares from the Czech Republic much cheaper than Britain. MPG around 34.

Pleasant and understanding vehicle unfortunately didn’t meet my expectations Martin was great very pleasant.
Perfect sports sedan, TDI engine is amazing!
Bought my '16 A6 3.0 TDI a year ago with 89k miles, now has almost 110k miles, and drives like a dream still. Can't even tell it's a diesel engine by the way it drives and how quiet it is. I drive a lot for work, and the gas mileage is amazing! Interior is comfy, classy, and roomy. Drives like butter, handles like a sports car. Exterior isn't too flashy, it's perfect. No issues, and my last checkup at the German export dealer was perfect. My favorite car I've owned, now I want an A8 L!

A dealership you can trust
I was looking for a specific car that was at this CarMax. Problem was that I live in Minnesota, not Chicago and would have to traveling a great distance for a car I had not seen other than in pics, potentially risking wasting a great deal of time and money. I had to trust Jonathan, my salesman, to tell me the condition of the car where the pics could not. He was completely honest and the car was exactly what he said it was. Between Jonathan and Adam, the sales manager i was able to close the deal and drive back to home within an hour. I am completely pleased with the car and 100% satisfied with the dealership. I guess you can trust a car dealership. I did and they did not let me down. Thanks guys.
Comfortable and reliable.
This car has met my needs, comfortable, reliable, seems economic, nice exterior and interior design, easy to operate, my kids enjoy it. It’s overall very recommended.

I had an outstanding experience with Eryk Buczynski at
I had an outstanding experience with Eryk Buczynski at Castle Volkswagen of Schaumburg. From the moment I walked in, Eryk was incredibly welcoming, knowledgeable, and genuinely focused on helping me find the perfect vehicle. He took the time to listen to my needs, answered all my questions with patience, and provided clear, transparent information about pricing, options, and financing. What stood out most was Eryk’s dedication to ensuring I felt comfortable and confident with my decision. He guided me through the features of the car, demonstrated how everything worked, and followed up afterward to make sure I was enjoying my new vehicle. The entire process was smooth, efficient, and stress-free. If you’re shopping for a new or used vehicle in the Schaumburg area, I highly recommend asking for Eryk. His professionalism, integrity, and customer-first approach truly set him apart. Castle Volkswagen of Schaumburg is fortunate to have him on the team. Thank you, Eryk, for a fantastic car-buying experience!
Brilliant Car, expert servicing
Excellent car, just done 122K and runs like a dream, had it serviced regular by brilliant guys at the general motor company in Stockport in UK. Didn't want to trade in when lease finished. Looking to get many more miles Peter Gilligan

A must stop for Audi newbies
We had been searching causally for a few months for a plug in hybrid suv. We had toured a bunch of different brands and nothing felt right. We made an appt to see one at this dealership and we’re blown away. The team gave us our most in depth tour (over 2 hours ), helped us navigate finances and find the perfect vehicle. We loved working with Wesley and Jazmin. We’re based in the city, but found the dealership so easy to get to. As young professionals, this was our first big car purchase and know it won’t be out last with this team.
Excellent car and reliable.
Great car, comfortable and excellent performance. The buying process was made easy by knowledeable sales and support staff. Pleasant dealership. High tech sales and supportm

Must buy at a realistic price.
Such a gorgeous vehicle, inside and out. Haven’t had a single issue with it for over a year of having it used. Inside of the vehicle is super roomy, and driving feels very comfortable, and really we’ll insulated!
