I had a great experience from the minute I walked in the door. Everyone who walked by spoke and made sure I was being helped if they saw me sitting alone at any time.
Perfect for the family of 6 like me.😍😍😍
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.

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

I recently bought a 2015 Porsche Macan S from Alix and the buying process was so easy and quick! I had a great buying experience and the staff there made sure I was well taken care of. Their inventory is great, I will definitely be keeping them in mind in the future! I love my car so much, thank you!
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.

I had an amazing experience working with Mohammad at One
I had an amazing experience working with Mohammad at One Legacy Motors. He was professional, patient, and genuinely cared about helping me find the right car. From start to finish, he made the process easy and stress-free. He answered all my questions, gave honest advice, and never once made me feel pressured. I highly recommend asking for Mohammad if you’re looking for great service and a smooth car-buying experience!
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!

Jason Alvarez helped me purchase just the car I was
Jason Alvarez helped me purchase just the car I was looking for! He was patient with my questions, and I felt free to make the decisions I wanted. He even gave me a ride from my home to the dealership on the day I picked up my car and also befriended my dachshund who came with me. It was a very pleasant buying experience!
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.

Great customer service!
Brandon helped out my wife and I and he was an excellent person to deal with. We could not come to terms on the Lexus LS 460 but the experience was great. We just were not in the financial position to purchase a car that needed $2,400 in structural repairs right out of the lot.

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..

Customer Service Experience Turned Around
After having a very unpleasant customer service experience with Jennifer Collins, a new service advisor was assigned to me. I was extremely pleased Clayton Fraizer. He took the time give me a call to introduce himself and was very warm, positive and professional. Once my vehicle was ready for pick-up, he called again, greeted me upon my arrival, and did a proper checkout to ensure that the window tint and window seal repair exceeded my expectations. As a brand new Mercedes Benz - Plano service department customer, I am happy to say that Clayton COMPLETELY turned around my overall experience and perceptions of this department. His customer service definitely matched the Mercedes Benz brand which is what I expected from the beginning. As a result, I will continue to work with him in the future.

Smooth Buying Experience
Friendly and professional staff. They were very hospitable and made the buying process as smooth as possible. They explained everything to us clearly and didn't try to sneak in any extra charges. Our salesman, Eddie, took especially good care of us and was very patient as we thoroughly looked over the car we were interested in and took our time to make our decision. The car we purchased wasn't a Mercedes and was less luxurious and less expensive than what you would typically expect from a high-end luxury car dealership, but they didn't treat us any differently because of that. Highly recommended!

Darren Shin -EXTREMELY knowledgeable Sales Advisor
We built/ordered 2024 GLC300 for my wife in May 2023. Took delivery on 12/1/2023. Darren Shin was our sales advisor. We moved our business from another Mercedes dealer because Darren was EXTREMELY knowledgeable about the Mercedes autos, options, process, timeline, etc. He did NOT use any pressure whatsoever. he focused on educating us to ensure the vehicle was EXACTLY what my wife wanted. If I had a sales opening in my firm, he is exactly the high performing sales person who I would hire!! Kudos and well done.

First time buying a car online. The most awesome experience ever. Salesman, Adrian was very responsive to texts and phone calls. He went out of his way to make sure I had no worries. He even dealt with a couple of "psycho moments"....lol Great personality for sure! Even responded to text on his days off! (Sorry Adrian) The car is beautiful and looks brand new!

I recently purchased a used car from Ottosource
I recently purchased a used car from Art Wilson at Ottosource. I am very happy with the service I received, the ease of the no pressure sales process and love the car I bought.
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.
