Vel is a great sales guy.
Vel is a great sales guy. Very responsive and will work with the customer. We drove from MI with a trade in and they honored their offer. There were a couple minor things like steering wheel was more worn than we would have expected given the nice condition of the rest of the car. Small headliner plug interior for convertible top was missing. Other than that it was a smooth transaction.

I’ve had many Mercedes-Benz models over the years, including AMG’s and the GLS 450 a wheel drive with 23 inch wheels makes this car track like a race car. Out of all the Mercedes-Benz models this is the best one you’ve ever had. The second row seats reclining just like the front row seats privacy shades and the third row comes in handy when needed plenty of cargo space for all those trips to the airport to pick up family and friends. It gets great gas mileage then other SUVs and it doesn’t look like a box like it’s competition. I had the dealer put the Mercedes-Benz standup medallion on the hood even though it has a huge Mercedes-Benz insignia on the front. I just like to see the stand up Star medallion from the driver seat guide me down the road..

The dealership had a great selection of quality used
The dealership had a great selection of quality used cars, all well-maintained and reasonably priced. I appreciated their transparency and honesty throughout the process, including providing detailed vehicle history reports. The financing process was also seamless, offering several options and explaining everything clearly. I left feeling confident and satisfied with my purchase. Overall, I highly recommend Affinity Auto Sales to anyone looking for a reliable used car and a pleasant buying experience. Thank you to the entire team for making this such a positive experience!
Best SUV we've ever owned.
Exceptional vehicle in the SUV class. We drove the BMW X7, Audi Q7, Volvo XC90 and this GLS 450 just kept blowing them out of the water. The ride is amazing and we feel the comfort level and size is the best

I recently had the pleasure of working with Exclusive
I recently had the pleasure of working with Exclusive Autohaus, and I can confidently say that they provide an outstanding experience from start to finish. From the moment I walked in, the staff was incredibly friendly and professional. They made me feel welcome and took the time to understand my needs and preferences. About four months ago, I purchased a 2014 Audi R8 from them, and I couldn’t be happier with my decision. The car is in pristine condition, and it’s clear that Exclusive Autohaus takes great care in selecting and maintaining their vehicles. The entire process was smooth and transparent, and I never felt pressured, which is a huge plus when buying a car. What really stood out was the level of customer service. They went above and beyond to ensure I was satisfied, answering all my questions and offering helpful advice. The team at Exclusive Autohaus is knowledgeable and truly cares about providing an exceptional experience. If you’re in the market for a vehicle and want excellent service, a great selection, and a no-hassle process, I highly recommend checking them out. I’ll definitely be returning for any future car purchases!
Perfect for the family of 6 like me.😍😍😍
I have this car for almost 6 years I have no major problem at all. We always use this for long drive and short heavy cargo. Excellent SUV.

Happy shopping and purchase
I was very pleased with my experience. I started at CarMax to "try on" several cars from several manufacturers. The salesman (Jack) was happy to oblige, despite it being cold and rainy. We walked the lot and I sat in ~20 cars. I went home and researched them some more, scheduled a few to test drive and came back on Jack's day off. This time, I worked with Brandon for a few test drives and discussed other vehicles at nearby CarMax locations. They found a vehicle that fit my requirements and transported it in for me to test drive. A few days later, I was back for the final test drive, loved the car and purchased it. Jack and Brandon kept good communication, weren't pushy and were a pleasure to work with. The business office was quick and explained the paperwork and processes effectively. Now, two weeks on, I'm very pleased with my car and experience. Thanks!

Great buying experience with Okaz Motors.
Great buying experience with Okaz Motors. My salesman Fahad was wonderful. Super helpful without any high pressure sales tactics. The truck I purchased was in great shape and was priced right. There lot is very impressive with lots of high end vehicles. I will recommend Okaz to all my family and friends who are looking for a used vehicle.
Great Vehicle
I absolutely love the feel and performance of this suv. The electronics are state of the art. Excellent road performance in rain, snow or wind. My only complaint is the running board- it needs to be at least 1 inch wider. Actually dangerous in snow and ice.

I just purchased a Infiniti QX 60 from Motor Werks in Barrington, IL. This will be my third purchase from this dealership and my second experience with Mark Smith my salesman. Mark Smith and Lorena Mena the sales manager make car purchasing a enjoyable experience. No pressure whatsoever and after negotiating a fair deal I drove home in my new car. You would be extremely hard pressed to find a more reputable and honest dealer. No hidden fees and the whole process was completed in about an hour. If you are looking for a new or used Infinti let Mark help you with your search. Tell Mark that Kevin sent you!
You get what you pay for
We are in our first five months and I seriously believe all the safety options have kept me out of at least two accidents. The car on the highway practically drives itself while giving me a message. Audio systems are excellent. The 450 GLS makes driving a bit of a joy.

Best dealership in town.
Best dealership in town. There’s no other dealer in Illinois that compares to this one. I’m a passionate automobile enthusiast with no patience for xx and THIS dealer has NONE of that. I walked in and I was greeted softly and warmly by the front desk discussing the reason for my visit and understanding if I was browsing or looking for something specific. When I spoke about a specific vehicle I wanted I was referred to Tiffany the sales manager. She was as warm and welcoming as the front desk people were. Tiffany paid careful attention to what I wanted and what I was looking for. I never felt rushed or pressured. I felt MY time and what I wanted is what mattered to her, which it did! She introduced me to her product specialist Roland ( With a cool Cowboy hat and a great sense of humor to accompany it). While Roland knew full well I wasn’t in the market to buy a car in the near future he still spent almost 2 hours with me discussing my options, my needs, and how to get those needs taken care of. By the end of my visit, Roland helped me place an order for the exact vehicle I want. Despite not making a sale that day, they invested those nearly 2 hours in MY NEEDS and they showed me how much MY time meant to them. I’m almost 40 years old and I’ve never purchased a brand new car before in my life, and you know what? This is the place that’s going to happen and I couldn’t be happier. Thank you Roland for explaining things so well and exploring everything down to the last detail to get me what I want and what I need. Bob Rohrmans Ford will be my first new car purchase and I’m confident it wont be my last. If you appreciate a no pressure environment that cares about your time, your needs, and communicates things clearly and easily….. This is the place for you
