Lots of cars to choose from
Hi the dealership is wonderful as the staff are extremely knowledgeable and they have great service, but the only thing that hurts them is the price. The cars are thousands of dollars higher than other place I looked so did not buy from the dealer.
Most incredible car I’ve ever owned.
This is my second Mercedes-Benz. It’s absolutely the most incredible car I’ve ever owned. I was blessed to be able to custom order this car to have everything I wanted and more inside and out! It literally came straight from Germany to the dealership for me. It drives like a dream. It’s absolutely gorgeous. The technology inside is so amazing! It can drive economically. It can drive more sporty if you want it to. It has so many options and settings for drivers of all kinds. Needless to say, it’s pure luxury inside. You’ll feel incredibly spoiled!

I love my car and I would recommend it to anyone looking for a small SUV ?rides good?looks good.. And it is a nice color
Haven't put many miles on due to snow and ice.
Not enough miles driven to fairly evaluate but look forward to driving when weather is better. I have high expectations! I'll need time to get used to the console controls.

Fast service and very professional
I bought a year old BMW. The price was better than I found at other dealerships. They were prepared to go as slow as I wanted and answer all my questions, but that's not what I wanted. I wanted fast! So after a quick test drive went in and signed the paperwork, while they washed it for me. They let me leave my old car there and drive my new car home. There was a headlight malfunction and they said it was completely covered under warranty. However, because it was a software issue, Carmax said I needed to take it to BMW, but that Carmax would cover any costs. They were true to their word!

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!
The features are amazing,stylish .
Great driving comfort,loaded with features. Safety is definitely a priority with the MB engineering . I have leased a total of 4 Mercedes and totally satisfied with every single one.

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.

Excellent Personnel
I approached buying my Miata with usual fear and trepidation... price was a concern... I didn't want to part with my 2001, yet thought it was time. Lori was very patient and relaxed. At one point I decided not to buy and she, without argument, placed it back on inventory. Also, at other points I'd dealt with Mark and Luke, co-workers with Lori--all cooperated with each other in a very professional and friendly spirit. I had two issues under 30 day warrantee--I was given a loaner car and was called in 1/2 day that car was ready! Location is a problem, gps a necessity for someone new to Dallas. I can now find it after 8 or so visits, but laugh when I finally do get there each time. I'll probably return for service, as I have a warrantee contract, though it allows me to go elsewhere. I feel I have some real and honest friends there, a good experience.

Highly Recommend Zarina and Clay Cooley!
Ask for Zarina Ward. She makes the process smooth. I bought the new VW ID.4 and had to order it in advance. Everything Zarina told me was accurate. She shot straight with me and kept her word throughout the entire process. I highly recommend Zarina and Clay Cooley VW Richardson!
