Tuan is an excellent person to reach out to when
Tuan is an excellent person to reach out to when purchasing a vehicle!! Tuan understood my price points and thoughts on theri vehicle.
My Mercedes Benz SUV
I am a senior citizen and I want to feel secure while driving, and the SUV gives me that. I am on the short side so getting in and out was a new experience for me, but I learned how to manage it. Once, I found the seat setting the visibility is exceptionally good. It handles nicely on the road with quick pick-up, and the gas mileage is about average.

ROCKING MY SABLE BROWN LEATHER SEATS!
I'm not new to the Mercedes brand, as this is my 4th. This is, however, my first try at the Mercedes SUV. So far, I'm extremely happy. Favorite feature has to be the camel leather seats...an impressive update from the MB-Tex.

I have trusted and used Henry Brown for repairs since
I have trusted and used Henry Brown for repairs since purchasing the Tahoe from their CASA Grande, AZ store in 2009. First with Mike Meade and now with Lou. Both very professional, knowledgeable and helpful.
Pleasant drive, but not driver friendly.
A pleasant driving car. Very dependable. But, in my opinion, not very user friendly. The controls for features like like wipers, lights, and GPS are complex and buried under layers. The GPS took me over a route that was 1 hour longer than normal on a 5 hour trip because GPS had avoid carpool lanes turned on. Had to call MB at an 800 number to find out the feature even existed. Also, I HATE the run flat tires.

This car excess my expectation it is a dream care. I feel so comfortable in it, it has a lot of space for me. I love the automatic park assistance and touch screen.

GLC Coupe
I bought the GLC Coupe with the AMG package and it’s the nicest car I have ever owned. The unique two tone (black and cranberry) interior definitely sets it apart from other cars.

Best car buying experience
Excellent car buying experience. I felt this dealership put my needs first, ahead of their own. They acted with integrity, honesty and professionalism at every step, which is a refreshing way to buy a car. Also when returning for follow-up maintenance, again they exceeded my expectations. It was my first Mercedes purchase and this dealership was hands down the best, compared to others visited. The facility is top-notch, the people are kind, friendly and customer focused. There was zero pressure - it was a truly professional experience. Plus a more than fair deal. This is an excellent dealership - was obvious the people are focused on operating with highest integrity. Would definitely recommend!

My Hat's Off To Those Involved
On February 21st.,2023, we took our 2022 Santa Fe to Earnhardt Hyundai of Scottsdale for routine maintenance & factory recall. After driving home, approx. 45 miles, the car set in our garage undriven until Feb. 23rd. On that date I found a considerable amount of oil under the car. In further investigation and checking under the hood, I found the engine compartment saturated with motor oil. I immediately called Earnhardt Hyundai of Scottsdale who contacted Valley Towing to pick up my car and deliver it to their Service Dept. The service mgr. contacted me by phone within two hours to tell me they located the problem which turned out to be the dip stick had failed to be fully replaced. He also assured me that they would clean up the engine compartment and return my car the following day. On Feb. 24th., Howard (Store Greeter), called to tell me they had completed replacing the engine oil, washed the car, detailed the engine compartment and would deliver the car to our home with one hour. As promised, Howard arrived at our home with the car and it was as clean as the day we made the new car purchase. Howard also filled the the gas tank and offered to clean up our garage floor. We're all human and capable of making mistakes as did the mechanic, but the follow up by each Earnhardt Hyundai Store Employee involved in this matter was professional, courteous and understanding (including the store phone operator). Even though we have a Hyundai Dealer closer to our home, we're certain to use only the Scottsdale Earnhardt Hyundai Dealer for our future service needs and vehicle replacement when due.

Had a good experience at Brown and Brown sales this last
Had a good experience at Brown and Brown sales this last week. Worked with Jordan and he got me a pretty good deal on a car I've been wanting. Helpful, friendly staff and didn't feel pressured to buy. Good vibes from everyone there. I would recommend to friends and family.
There are 20 matching cars close to your year range.
