Jason did amazing Job I can’t believe the deal I got
Jason did amazing Job I can’t believe the deal I got thank you so much Luxury AutoMaxx I came for. GMC and left with a Honda Odyssey for my family I’m so has happy
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.

Great dealership. I would recommend buying and taking your vehicle at this dealership. Great people.

Special. A delight to drive. Love the way it handles. Extremely responsive, both acceleration and steering. Cabin is very quiet and at night almost too relaxing.

My Sixth Mercedes Benz-Fantastic Cars
The GLS has the luxury of a sedan and the versatility of an SUV. This is the fourth GL series that I have had and would not consider another vehicle.

Marty Lucas did a fantastic job.
Marty Lucas did a fantastic job. He is very professional and friendly and has a ton of product knowledge. I would highly recommend seeing Marty if you are looking to buy a vehicle. Tony Griffith handled the financing and was also wonderful to work with. The whole experience was great and another highlight is we didn't have to deal with them having added packages on the vehicles.
Love this car
This car met all my needs and more. Love the interior and the way its moves. So comfortable and reliable! Very pleased with this car!

Great service as always.
Great service as always. Really liked Francisco. He was very personable and extremely helpful. Very easy to work with. And that's all I have to say.

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 staff was efficient and my car is running smoothly. My vehicle was covered under warranty but it was difficult to work out due to it being a weekend. The staff was very helpful with getting back to me and keeping me updated through the next week and were able to fit me in right after.
Large yet stylish enough to carpool the Grands
We just bought this car. Comfortable, roomy, easy to drive. Not quite a luxury ride that the Lexus GL has but performs well. Takes a second to get comfortable with the bells and whistles. Beautiful car, 2 2 2 seating. Easy for kids to get in without climbing over or moving a seat. We bought this SUV for me to drive around town as well as to school carpool my grandchildren. So far...very pleased. This is my third Mercedes. My only complaint with Mercedes is the fuel tank on the passenger side. I feel a little more vulnerable being on the opposite side of the driver side when pumping fuel. I assume it has been this way for years. I guess safety at the gas station was not as big of a concern as it is today. If considering a luxury SUV test drive. I think you will be pleased/

Liz in sales was always helpful and made the buying
Liz in sales was always helpful and made the buying process a breeze. She addressed all my concerns about the Carfax report, pricing & extra keys. The dealership's facilities are convenient & very clean. The vehicle itself was in great condition. The financing process can be made more transparent. It would be helpful to know about the extended warranty options beforehand as cost of these options can add 10-20% to the cost of the car. It is hard to make this decision at the last moment. However, I could have added to the financing.

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.

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.

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

Above and Beyond
We purchased my son’s first car from BG Motor Cars. Fair prices, no pressure sales but very accommodating. This is a small dealership and the owner handles almost every aspect personally. I will say that the owner does go above and beyond to deliver quality and ensure his customers are satisfied. Even though we did buy a used vehicle without a guarantee, the owner exceeded our expectations by making sure the small issue we did experience after purchase was promptly addressed. You are not just a number here. You are treated like family and it is clear that the Business model is to create a solid reputation and make repeat customers.
The vehicle was a good experience for the first ti
The interior was very comfortable and the color combination made the experience very nice , was very surprised by the power that came from the engine
