Great customer service
I contacted the dealership for a Flying Spur that I was Interested in. The sales manager, Saleem Beg contacted me promptly to send my all the information on the vehicle. He was very professional and helped out a lot in getting numbers to me in minutes. I couldn't come to the city to do a test drive, Saleem offered that someone can bring the car to my home which was a very generous offer. I went with another car but was really impressed with Saleem, definitely would recommend this dealership and will go to them in the future.
Love my Mercedes
I have been driving Mercedes Benz s class vehicles for over 10 years, traded every 3-4 years and have been very happy, always have them serviced at the dealer, always received a loaner, no complaints.

An Absolute Dream
I have owned 6 S Class (SonderKlas) cars in my life and each and every single one has been problem free and a pure joy to own, drive, and admire. The 2021 S580 however.. Well this car is truly something special and not an incremental upgrade! This thing is crazy

Phillips Chevrolet was EXCELLENT.
Phillips Chevrolet was EXCELLENT. My amazing team consisted of: Jordan my salesman that closed the deal, Anthony the manager, and Rami the first salesman I spoke to. I was on a mission. I began an aggressive search for a car for my daughters 21st bday. I needed her in a safe used car, with low miles. I picked Phillips Chevrolet by accident, after I had a horrific experience with another dealership. The night before I paid the other dealership 18,800 cash for a 2024 Altima, but canceled the wire after they argued with me- and refused- to make me a 2nd key. Phillips didn't argue about ANYTHING. They showed me a fabulous car- a 2022 Corolla with low miles. It was a $400 difference, and the BEST $400 I have spent. I left the dealership laughing with the manager, hugging the salesman, and promising to buy all my future cars from them. They did not haggle with me, and I respected their position on the pricing. They went down a few hundred, but couldn't any further--- it was already below market value. My husband checked and said it was way under priced. My brother who is a large man- gave it a xxxx of a test drive- through the back woods, fast turns, up hills, etc. I fussed at him for shaking up the car. He said it was a strong car, that rode smoothly. I felt good that they weren't selling me a lemon. To guarantee they weren't - we negotiated to include the extended bumper to bumper warranty. I went back the next day to pick up a clean, freshly washed car. At the other dealership I was nervous when I signed, and second guessed myself all throughout the deal. Whereas, I was thrilled and excited about the car from Phillips Chevrolet. I gladly wired them the $19,000 + and took photos of my car. After taking photos with everyone, and my brother getting his $100 referral (which he didn't share with me :(.. LOL. My husband came to thank them for not causing me to "snap off" like the other dealership. He said - now he can have Peace in the House. After the hugs, photos, and jokes they gifted me with sweatshirts, hats, and bags. Now I can buy a big red bow, and give it to my daughter. I'm making her wear the sweatshirt and hat for the photos. SIDEBAR: Out of the last 5 car purchases I have made in 7 years- this was the absolute BEST experience ever!!!! Colleen & Family Loved Phillips & their Awesome Team!!!
Luxury
Luxury at its best, you can’t get better than that with this price range. S 580 is the way to go, the 8 cylinders are so smooth yet so sporty. This car can be Rolls Royce luxury and lamborghini urus if it wants

This was the best purchasing experiences I have ever had. The staff were friendly and very helpful. The vehicle was as advertised. Sometimes pictures don't accurately depict the vehicle, not in this case. I would highly recommend CAW to anyone looking to purchase a quality vehicle and be treated like an MVP!
