Used Mercedes-Benz GLS 450 SUVs for sale near Frisco, TX

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.

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.

they replied to all of my messages and were easy to work with on numbers

Wanted more information on the damage to a car and none was giving to me

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.

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!

I purchased my first car here and the process was so amazing everyone was so kind and tentative. I will send me entire family here if they need a quality vehicle.

Absolutely the best Car buying experience ever!! I purchased my first vehicle 2/2023 And they definitely did not disappoint. I was in dire need of the vehicle and they exceeded my needs. Fast forward to yesterday, I worked with Sean and he was very patient and helpful with not only offering the perfect vehicle, but also assisted with submitting us to lenders for financing. I am Very grateful I found this gem of a dealer. No haggling, No pressure, just a very respectful & honest business!

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

Fidel has excellent customer service! I was out within the hour from the time I scheduled my Oil Change. Will definitely be looking for him again whenever I bring my car in for servicing in the near future.

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.

Easy to work with. Car was exactly as described, no surprises. 15 minimum, needed 4 more words....

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

Outstanding customer service during test drives yesterday and today with Mr Glen was outstanding and very professional with patience and caring . Also Mr Chris in finance department during purchasing my car who too his tone with passionate and caring to help and facilitate the process . Thank you ??

Clear communication, no pressure, knowledgeable - they respected our time and our preferences. We were made aware of various protection packages, without any pressure or wasted time.

Good experience in dealing with Kerron at dallas lease returns, would Definitely buy another vehicle from him !

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.

Love y’all guys so much thanks for y’all making this the bestExperience I have yet in buying cars you keep up the good work and get your clientele the best y’all can give

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 recently purchased a vehicle from Top Line Auto, and the experience was outstanding from start to finish. The team was incredibly knowledgeable, attentive, and genuinely committed to making sure I found the perfect car. They went above and beyond in providing detailed information about the vehicle, including mileage, Carfax history, and available warranties, which made me feel confident in my purchase. The process was smooth and stress-free, with no pressure or rush to make a decision. I also appreciated their willingness to work with my schedule and accommodate my needs. The level of customer service at Top Line Auto is truly exceptional, and I would highly recommend them to anyone looking for a quality vehicle and a hassle-free buying experience.

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 purchased a 2020 Mercedes G550 from Top Line Auto, and I couldn’t be happier! The car is absolutely phenomenal—every detail exceeds my expectations. The service I received was exceptional, going above and beyond to ensure a seamless experience. If you’re in the market for a vehicle, I highly recommend Top Line Auto. They truly deliver excellence in both cars and customer care!

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 highly recommend Beatriz, an excellent salesperson, attentive, she cares about providing you with the best service, and I hope she reads this (Mariluz used vehicle Navigator 2020). I also hope to return in the future because they made me feel very good, and I plan to buy a vehicle in the future, and it 👍👍👍

We just bought this car. Comfortable, roomy, easy to drive. Not quite a luxury ride that the Lexus GL has but performs well. Takes a second to get comfortable with the bells and whistles. Beautiful car, 2 2 2 seating. Easy for kids to get in without climbing over or moving a seat. We bought this SUV for me to drive around town as well as to school carpool my grandchildren. So far...very pleased. This is my third Mercedes. My only complaint with Mercedes is the fuel tank on the passenger side. I feel a little more vulnerable being on the opposite side of the driver side when pumping fuel. I assume it has been this way for years. I guess safety at the gas station was not as big of a concern as it is today. If considering a luxury SUV test drive. I think you will be pleased/

Carl Miller answered questions I forgot to ask. Straightforward and not pushy, very refreshing. I would buy from them again. This was an out-of-town purchase and it was a piece of cake to get the job done.

The Mercedes GLS is my second Mercedes and like always very satisfactory process to buy at the dealer. Great vehicle! Outstanding engine and transmission! Very confortable for the entire family 😂

Very professional group of people. They did a great job of contacting me and following up. Sent me all the info I needed for the vehicle I was interested in.

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.

Steve was amazing his GM and Cadillac knowledge and honesty was greatly appreciated! Quincy was great as well!

So I pretty much been dealing with one Gentleman name Craig and have been an easy person to speak with and very knowledgeable about things I ask of him.

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.
