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!

Julio R and Gary K did what was necessary to get my car repaired in a short time with care and respect.

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.

I am a 60 year old person and I have bought many cars from many dealerships . Buying a car from dealerships have been very stressful and unplesent. Then I stumbled upon Autohaus on Edens . It was an unbelievably pleasant and friendly experience. Just bought a car from Autohause and I will never use another dealership for service or purchasing another car other than Autohause on Edens. Every one in that Dealership is amazing. Call Bobby, if you are in the market for car. He is the best.

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.

We recently purchased a Porsche Macan from Napleton Maserati of Downers Grove, and I can’t say enough about the exceptional service we received from start to finish. Even though we’re located all the way in Seattle and never saw the vehicle in person before buying, the entire experience was seamless, trustworthy, and surprisingly personal. From the very beginning, Orsie on the sales side went above and beyond — answering every question promptly, providing detailed photos and information, and making us feel confident and excited about the purchase. His honesty and commitment to service were truly refreshing. On the financing side, Alex made the entire process smooth and straightforward. He explained everything clearly, helped us understand all options, and kept things moving quickly despite the distance. What impressed us most was the trust and transparency every step of the way. In an age where buying a car sight unseen can feel risky, they built an experience grounded in professionalism and care. We would highly recommend Napleton Maserati of Downers Grove to anyone — no matter where you're located. They proved that exceptional service and trust can travel any distance.

Fast and easy. All staff was pleasant, well spoken and mannered. Made an out of state purchase with a few email and phone calls. Sales person Luke was excellent.

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..

Made me feel like family as soon as I walked in very helpful and accommodating to my needs didn?t feel rushed at all great staff and location overall.

Excellent service from Joe Bednarek Knowledgeable-efficient and personable Always confident the right work will be done

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.

From the moments I got in the dealership until I left I was treated very nice and very welcomed. I looked at Lexus RX and end up buying it because I felt comfortable and car is clean with good competitive price. Very recommend

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.

Exceptional service from the sales team and a very honest and transparent transaction. The team there did an amazing job taking care of me from putting numbers together, to ordering, to delivery and taking care of my trade! Thank you Fields BMW!

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.

Very professional and helpful. Also, the salesperson was very helpful and accommodating. I'm happy to recommend!

I don’t usually write reviews, but this experience was truly exceptional. Working with Matt from Executive Motor Carz was an absolute pleasure. From the start, his and the team's professionalism, honesty, and transparency stood out - qualities that can be hard to find in the car-buying industry. I initially hesitated about purchasing a car sight unseen, but they made the entire process seamless and stress-free. Matt was incredibly patient with my many questions, always available to talk, and guided me through each step with complete transparency. His willingness to go the extra mile, including a detailed video walk-through where we tested every feature, gave me complete confidence in my purchase. Any minor thing that came up was addressed and resolved immediately. It was clear from the beginning that EMC is committed to quality and customer satisfaction. Even being out of state, I never once felt disconnected or uncertain about my decision. Now that I have the car, I couldn’t be happier! Without hesitation, I’d work with them again and recommend them to friends, family, and anyone looking for a reliable, honest dealership. If you’re considering purchasing a vehicle, *this is the place to do it.* Thanks again EMC team!

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

This was the best experience we’ve ever had in buying a car. Would recommend Mercedes Benz of Barrington. They were more than accommodating.

Overall I had a pleasant experience with this dealership and would definitely return when I purchase my next vehicle.

Prompt and courteous reply to my inquiries. Remained in contact but not pushy... good balance. Good 'dealer-sense' and manners.

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.

Got my car serviced here. Honestly I thought I was in for a lot of money on my Panamera but they replaced the engine for a great price …couldn’t be happier. Ask for Carlos

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 .

I have never bought a car online before let alone bought a car without even seeing it or driving it. I saw a Bentley Flying Spur for sale at Chicago Auto Gallery. I called and spoke to a salesperson named Steve. From the first hello on the phone until we closed the deal and the car was shipped to me Steve was fantastic. He did everything possible to ensure that I was satisfied with the car and the deal. Now here's the extra part that I was even shocked at myself. Once I got the car, I drove it and after 5 miles some of the lights came on such as check engine, ride height, traction control and ABS. I was initially immensely pissed. I called Steve and said you might want to get ahold of that driver who delivered this car and tell him to take it back. Steve suggested I take it to a certified mechanic near me and have it looked at to see what was the problem. Apparently when one light goes off, it triggers more lights to activate. I had it looked at and to fix the car right it was going to be over $3000. Steve took care of it and the dealership paid the whole bill. In my mind that was the most solid thing to do and he did it. He could have argued and tried to avoid it or said no, you bought it, you fix it. They did not do that to me. I'm in Pittsburgh and they are in Chicago. I know I had rights and could have just sent it back but I wanted that car and they fixed it for me. I appreciate everything they (Steve) did for me and I would definitely purchase another vehicle from them. Thank you again Steve and Chicago Auto Gallery.

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.

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

We drove from out of state to look at a vehicle. I asked a lot of questions before we traveled. The salesman was very honest about the condition of the vehicle and did a good job sharing pictures that I asked for. We were very happy with the price and condition of the vehicle. We have been driving the vehicle now for three weeks and there have been no surprises.

I was really excited to buy this car, I appreciate the fact they try to get me the best rate. The vehicle was so nice for the price and year, I couldn’t get anything better than this car
