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.

My experience at Affinity Auto Sale was the best
My experience at Affinity Auto Sale was the best experience I done had with a car dealership. All the guys was cool especially my salesman Henry. He was quick at getting the business done I was in and out of there with no problems. If you in need of a great vehicle and awesome service give these guys a visit you will love. 5stars
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

My overall experience has been great at this dealership.
My overall experience has been great at this dealership. I came to this dealership a year ago and due to my credit not being so great I was not able to buy. The sales manager Farhan is great and I like to thank him for how he helped me and guide to get my credit strong. Now after 1 year I came back to this dealership to buy a car. The salesman was extremely helpful and he also did excellent job with everything. I am extremely thankful and very appreciative for all that this dealership do for me. I buy a low miles Fiat from this dealership. They helped me get a very good rate from a bank. I will come back to buy my dream Mustang from them in future. Thank you!!! 😊
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.

Great experience
Great car at a fair price. Shaun was straight forward and honest. I’d been looking for a specific car and the one I bought from him was in-line with market price, as well as condition. Easy transaction.
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

Courteous and straightforward
No nonsense, honest and transparent pricing, knowledgeable and accommodating. My salesperson interrupted his vacation to fit my schedule and spent the time I needed to become familiar with the car, the options, the financing and the process.
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.
