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.
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.

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

Amazing, hospitable, and upfront people to do business with. This was my second time getting a car here, always a pleasure to talk with Mel and Sef!
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

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.

Awesome service!
Awesome service! They are the most transparent dealer that I have ever been to. Highly recommend Mike and Harris were awesome. Helped my dad and I purchase a new truck
Almost perfect for luxury family truckster
Owned this suv for 15 months purchased certified preowned with 33k miles and about half the price of new. The truck has only two issues to note but otherwise rides, drives and in all other respects is far and away the best automobile I’ve owned - which saying a lot for an old guy. The standard tires are nearly useless in snow and ice and we hope an aftermarket replacement will address the issue later this fall. The more annoying downfall is that although the ride is otherwise amazing, the truck handles sharp bumps very poorly - almost the feeling of a car with workout struts. I have had the struts replaced under extended warranty but the improvement was marginal. For most drivers the suspension issue wouldn’t likely be as much an annoyance but for my fellow ocders, be warned. I would buy the truck again, however.

I had a great experience buying my tesla from highline
I had a great experience buying my tesla from highline auto sales, specifically Scott. We were able to talk and text to negotiate a price both for the car I was buying, and the car I was selling. When I came in to test drive the vehicle, the car operated as expected. Once we got to the buying process, I was in and out of there in 45 minutes, with all the documents signed, and highline stuck to their word on the price we agreed upon on the phone. It was a flawless experience. Highly recommend them for a used tesla.
very roomy and functional
I have test drive the range rover the X7 and I find this is the best for me , it has the room and comfort plus all the safety plenty of power too with a good mileage for a car this size .

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.
I’ve had many Mercedes-Benz models over the years,
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..

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

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.

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.

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.

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.

Great service and fair pricing
Just wanted to mention that I had a great experience buying my F-Pace from Patrick Jaguar of Naperville. Dale was just fantastic and went above and beyond helping me during the the whole buying process. The rest of the team (Finance & GM) was also excellent in their interactions with me. I initially chose Patrick Jaguar because they were one of only 2 Jaguar dealerships in the area that were not marking up their vehicles over MSRP, specially the hard to get ones like the F-Pace SVR which I bought. I've only needed to use their service department for a minor cosmetic issue that was sorted out in one day. Great job all around.
