Used Mercedes-Benz C-Class for sale near Hayward, CA

I had an absolutely amazing experience working with Diana, hands down one of the best car sales professionals I?ve ever dealt with. From the moment I walked in, she was welcoming, knowledgeable, and genuinely focused on helping me find exactly what I wanted, not just making a sale. She took the time to understand my needs, answered every question with patience, and made the entire process feel smooth and stress-free. What really stood out about Diana was her transparency and professionalism. There was no pressure, no games just honest guidance and real support. She went above and beyond to make sure I felt confident in my decision, and you can truly tell she cares about her clients. I also want to give a big thank you to the manager, Amine, who was just as incredible. He made sure everything was handled efficiently and professionally, and together they created a top-tier experience from start to finish. If you?re looking for a dealership team that treats you with respect, delivers excellent service, and actually cares, ask for Diana and Amine. I?ll definitely be recommending them to everyone I know!

Vaani is amazing and has spoiled it for other dealerships! He had vehicle options for me and sent them to me to review prior to arrival. When I arrived the cars were available for me to look at and he accompanied me on the test drive pointing out major & minor features! I already had a Mercedes but was considering buying a non Mercedes (crazy huh) but the dealership I went to was not welcoming and more like I was an inconvenience. Very appreciative of the quick efficient process and I Love my new car💕

It’s my 12th Mercedes, this one by far is the best. My salesman Barry Martin always takes great care with me. The C Class technology is unbelievable

I like my rep David chao. He is great. Very helpful, not pushy. Facility is nice and spacious. Overall good experience. I highly recommend this dealership with my rep

2013 C350 RWD, AMG Performance and Handling package. 108,000 miles. Bought this car in '16 with 40,000 Miles. It continues to serve me well. The one major problem has been an anti-theft ignition switch that only the dealer can fix. Cost 2k to fix. This is the only repaired I've needed. I have had all scheduled maintenance done, Runs quite well, and still has great performance. Handling is the best.

The staff was very friendly and helpful through a frustrating situation with my bank. They called the bank on our behalf to sort out a situation with completing payment for the vehicle.

Shawn & Dave is an amazing car salesman they were very patient with me and help me very nice i give both of them 5stars each

Calvin did very good job in return of previous leased car and leasing new 2026 model 330i car. He did wonderful job in leasing of new car

I love my 300C with the AMG Package. You get a much sportier look and drive. The car rides very comfortably in Comfort Plus but you can put it in Sports Plus and it becomes a whole different car. It feels like the car stiffens up and the Torque is immediately right there. Also, the AMG Package comes with great brakes! At this price point, you're going to hear a slight wind noise at higher speeds and the back seats don't have a lot of legroom. But, as an entry-level Mercedes, this is the best Mercedes for value in my opinion.

The Rep. was so outstanding, and he was so helpful and helped us in the processes this was new to my son since he was purchasing his first car he had a great experience and also the sales rep was very attentive to our needs. I would defiantly go back again when I am looking.

I got everything take care of it. James is Great. I will tell my friends about this dealer. I'm going to continue all my cars service here.

C Class Mercedes are great vehicles. My last one lasted 7 years and 300,000 miles and this one seems even better. Improved interior and exterior styling with many new features. Drives smoothly with power and handles great.

BAO WAS SUCH A PLEASURE AT WC MERCEDES! The process went by so quick and he was extremely easy to talk to! Super accommodating and made me feel that it is through the entire process of getting my first Mercedes! He gave me exactly what I was asking for and more. I was truly appreciate you, Bao!

Most reliable and usefull car I've had as a daily driver. Everything in the interior is placed where it should be found functionally. Power, while not a muscle car, is more than adequate. Gas mileage is excellent. Adjusting from Comfort to Sport make a very noticeable impact on the driving experience from gear shifting to steering...

i love this dealer, we both two cars from here also my sister my causin

Robert and Alex were exceptional to deal with and made what could’ve been a difficult situation very pleasant!

We worked with Diego Soto and finance manager John to purchase a new 2022 VW Tiguan. From start to purchase we had a very good experience. Diego was professional, knowledgeable, and appropriately tuned into our pace. He matched our stride without ever being too “pushy” or “sales driven”. Our questions were answered quickly and easily. At our request, Diego put us in touch with a Service Manager to answer a few more technical questions about the SUV. We were able “shop locally” for a vehicle that matches our needs for this stage of life. And it is also great that we will be able to work with VW of Oakland for our service and maintenance needs - if and when it is required. All in all a very good experience !

It was a great experience buying mt car at the dealership. The look and features of the car is what attracted me to it. Donte is a great salesman, he is very knowledgeable. He answered all my questions and show me how to use all the features that the car has.

Andrew Medina service advisor was very helpful, efficient, knowledgeable, courageous and explained everything to me. I have an appointment at 7am and I was there at 6:40am and got my car out at 9:30a and that’s amazing . I like to acknowledge the techician team Robert Martin doing an outstanding job. To Andrew Medina and Robert Martin team keep up the good work and thank you for your hard work God Bless Orland

Absolutely love it, loaded with features including self parking. Sports car with different drive modes and yet luxury comfortable. So far not a single issue, very reliable. Highly recommend.

From initial contact to driving away with a new vehicle, the process was delightful. Highly recommend working with Sam Bernal. We'll be back for our next purchase.

We have a model 3 but we want a more comfortable car with similar performance on gas. This car with all the technology packages are more comfortable than model 3 but as smart in terms of driving assistance.

Navin was very helpful with the sale. He provided honest comprehensive details about car and provide all available history for it.

Love how easy the process was and even more so that it wasn’t high pressure. Every person I had interactions with during the process was super kind and patient (I’m recovering from spine surgery, a little foggy occasionally) I super appreciated being able to work with Bella on my purchase/paperwork. She’s very kind and personable. Many thanks

Truly great car driven it 20k miles over the year, no issues whatsoever (with proper maintenance of course). It gets Great gas mileage, some trips up to 28MPG!

The Diamond Auto staff were incredibly helpful, informative, efficient and honest with my purchase. I would absolutely do business with them in the future.

While getting groceries out of my car, My trunk came down on my head (C-300, 2017). Sometimes trunk opens after I lock the car. This is dangerous. What is the problem?

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.

Amazing car, handles great , amazing build quality and lots of power and spunk. Highly recommend, best car I’ve ever owned and will be sad to see it go.

They were 😃 they made the process easy and stress free for my daughter buying her first car.

May be too complicated to operate and use available functions . Too soon to tell. I still can not figure out how to set clock to DST!

The sales manager contacted me within a couple of hours. He invited me to come down for a test. Unfortunately I haven’t been able to meet the him. He has reached out since our first emails and he has been very professional. I appreciate his patience. I will try and meet him and test the BMW as soon as I can.
