The dealership contacted me and followed through on everything I asked and needed of them. Great overall experience.

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..

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.

It was a great experience, Will was very nice and well inform as to what was need for my break pads
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.

I just bought a one year old GLE 53 Coupe from michael Moran and had a great experience. He was a real professional, none of the typical car dealer nonsense. Everything was very easy and they delivered the car to me one day later. Very good experience
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.

Excellent experience with Doug and the whole team here! I knew what I wanted when I came in and they helped me find the right car at the right price! I would recommend them to anyone!
Love it so far
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.
