We stopped into Mercedes of Westmont as a second stop in
We stopped into Mercedes of Westmont as a second stop in our search for a new car. I am not really a fan of buying new cars, we typically buy a car and drive it until it’s dead, just so we don’t have to go thru the whole purchasing process of getting a new car. Chris at Mercedes of Westmont has completely changed my outlook on buying new cars! He is very professional, but yet relatable and understanding of the process and how to make it a pleasurable experience. We weren’t looking to purchase a car that day, but Chris really listened to our wants and needs and was able to find something for us that fit what we were looking for. He was very patient with us as we made our decision. Hands down the best experience I’ve had buying a car.

Overall good experience
Edit to prior review: We had an issue with a used CRV we bought there after a few days and had to bring it back but they did end up fixing it for us.
Very happy with my purchase from RBM Alpharetta.
Very happy with my purchase from RBM Alpharetta. The car has a very comfortable interior with all the features available. Handles well in town and on long drives. Good acceleration for such a big vehicle. Love the contemporary exterior.

Happy to purchase from this dealership rather than others in town! Turned out to be much better deal and car. Thank you
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.

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!

Great place, Great People, Great Cars
Very easy to work with. They let me do any checks I wanted, and I did a lot. No surprises and the car was excellent. Very quick buying process and no hassles at all. Definitively recommend this place. Just with I had more time to look at all the truly amazing cars. It would have taken all day!
I bought this vehicle is a retirement car.
I bought this vehicle is a retirement car. He moves great is responsive and very smooth. I wanted a retirement car for my retirement. I am 60 years old and I want that something that represent my current status with luxury interiors, beautiful blue color, and 20 inch wheels it is awesome looking. I can reach 70 in the blink of an eye any moves like it's going at 30 or 40 miles an hour. He has an awesome radio system. although it is not all digital, the radios are for listening. I have an excellent sound, System. Great interiors, great materials, great lighting if you're planning to buy a GLS the 450 is definitely one of your best choices.

Best car shopping experience!
After shopping around at few different dealerships, including the big BMW dealerships... I am extremely happy that I ended up here. My salesman Andrew was not pushy and hands down extremely knowledgeable. He dedicated his time to me and answered all the questions I had. Prices are noticeably lower and vehicles are in good condition. I waited to write this review and just want to say that I recommend this dealer to anyone thats looking for a used vehicle. My X5 has been bringing nothing but happiness thus far. FYI: they do financing here and the process is so quick. Thank you Andrew.
3 month review
I purchased the vehicle off of a lease in March with 60K miles. Overall I am pleased with the purchase. For the size the SUV is very nimble. The surround camera is a must. On a 350 mile round trip my 5'6" daughter-in-law had no issues sitting in the third row. I put the car seat for my grandson in the 2nd row drivers side because lifting the 2nd row back after 3rd row access is cumbersome and heavy on the drivers since you have to lift the middle seat as well. MB you have to make the 2nd row power back to upright position. Adaptive cruise control is outstanding but keep in mind you have to get the Driver Assistance package to get it. Harmon/Kardon surround sound is very nice. My big complaint is sometimes at speeds above 65 MPH there is front vibration. Does not happen all the time, sometimes I can cruise at 80 MPH and feels like I am sitting in my living room. I think it may have something to do with the Pirellis, I plan to switch very soon to Michelins. A very classy, roomy and comfortable SUV

Owner of the company reached out to me and take care off all issues even it was after work hours. Good customer service.
Great SUV
My 2 honest cents. Just bought the 2024 GLS 450 and it has a huge presence on road and it looks stunning! I went with the AMG exterior package and it looks way better than the base model. Ride quality is good, very smooth ride on freeways but you do feel small bumps on occasional city roads. The engine is good but I wish it had a bit more power, feels little laggy at low speeds but when you floor it it moves fast and steering is very responsive. On the other hand, cabin very silent tho and you barely get to hear road noise (without acoustic package). The Mileage is incredible on this, wasn't expecting to write about it but the GLS gives better mileage than my GLC. Interiors are amazing and is something no other manufacturer in this segment can match (especially at night with ambient lights), seats are super comfy and the infotainment screens are also crisp. Overall, love this SUV and i'm gonna keep it for a while.

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

This is the third S-class Mercedes I have purchased from
This is the third S-class Mercedes I have purchased from Mercedes-Benz of Westmont and I could not be happier. Going through the purchasing process was a delight because Kimberely Cager, my Sales Rep, and the sales management team made me feel better than just a valued customer. The real test, however, came when driving the new 2025 Mercedes S580. The supreme road handling and comfortable seating were nothing short of spectacular, and the many options like the integrated toll system (driving through tolls of different states has become hassle free), Apple CarPlay, and several driver-assist features has enhanced my driving experience. While understanding how to use and benefit from the many new features and options was a little daunting, Kimberely and the Product Concierge, Damir Oliynyk, have eased my doubts, and I?m looking forward to a long multi-state road trip.

Had my Mercedes Sprinter RV serviced here. I have used them in the past and it is always a great experience. Mark in service provides great customer service keeping me informed on what is going on during my appointment. They always go above and beyond. Their quotes are on point and I never feel like they are trying to take advantage of me. One of the best dealerships I have ever worked with.

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.
