Sales rep (Kenn) and GM (Bradley) were awesome to work with. Just the kind of buying experience everyone is looking for. Highly recommended!

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..

Tesla has mastered the art of combining luxury with
Tesla has mastered the art of combining luxury with sustainability. The acceleration is addictive—instant and smooth. We’ve taken several long trips and were amazed at how easy it is to plan routes with Tesla’s superchargers along the way. The seats are comfortable, and the quiet cabin makes every journey relaxing. It’s also great to know we’re driving a vehicle that’s environmentally friendly. Charging at home is simple and cost-effective. Owning a Tesla feels like being part of the future
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.

Just about 1 hour!
Ever bought a car in an hour? Go to Knauz. I was amazed. Including a short test drive, financing, and a car wash we were on the road in just over 1 hour. Brandon did a great job.

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.

Same day service for belts and spark plugs.
Same day service for belts and spark plugs. In and out the door fast. I even went to the wrong branch and was still served! Wonderfully efficient.
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.

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.
