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.

Infiniti of Denver truly is the best dealership
Infiniti of Denver truly is the best dealership experience I?ve ever had from buying, finance, service and everything else in between. The customer service here is top notch and everyone is always so friendly and helpful. Can?t recommend them enough they really changed my outlook and experience in a car dealership. They treat everyone like a part of their extended family and the amount of awards they have won shows just how great they are
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.

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

Best SUV we've ever owned.
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

We are in our first five months and I seriously believe all the safety options have kept me out of at least two accidents. The car on the highway practically drives itself while giving me a message. Audio systems are excellent. The 450 GLS makes driving a bit of a joy.

Professional from the start and they were not as much pressure as so many other dealers.
Almost perfect for luxury family truckster
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.

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.

Best service department in 50 years of driving
I've driven many makes of quality cars throughout my life and have had many experiences with a multitude of dealers and service centers. Prior to Prestige Audi my best experience was with a Volvo dealer/service center, but the folks at Prestige have exceeded even them. I purchased my Q7 five years ago from Prestige and have had it serviced there ever since - and I have been 100% pleased with those decisions. It's been an extremely reliable car and I've consistently received the best service I could ever hope for, let alone expect. Everyone on the Prestige staff has been very helpful and courteous, but a special shout out goes to Lucas who has been my Service Advisor for most of the past 5 years. I truly couldn't ask for more from any business or individual. 5 Stars and 2 Thumbs Up!

New Purchase: 2023 Porsche 718 Cayman GTS 4.0
The entire car purchase experience at Porsche Littleton (previously known as Stevinson Imports) was truly exceptional from start to finish!!! As a second time buyer from this dealership, I have had an opportunity to meet several individuals who are part of the team at Littleton. Everyone is outstanding (i.e. parts, service, sales, finance, and management departments)! During the most recent acquisition (2023 Porsche 718 Cayman GTS 4.0), highest praise goes to Anastasia Reison, Porsche Brand Ambassador, who assisted me throughout the long but definitely fun car ordering journey! Anastasia is not only extremely professional but also has a great sense of humor too. Ask for her by name when visiting Porsche Littleton and you will agree! For reference, the overall car purchase process spanned 1.5+ years from initial customer demand order submission to final vehicle delivery. However, this wait was without question certainly worth it and Porsche's Track Your Dream app provided great updates along the way! Again, a huge thanks to Anastasia and the whole team at Porsche Littleton! Happy Motoring, Daniel
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.
