Used Mercedes-Benz C-Class C 300 for sale near Mentone, CA

I have to say that I received the best Porsche buying experience from Porsche of Riverside. If you’re in the market for any vehicle at Porsche of riverside, definitely ask for Rob Owen! From the beginning to the end, Rob provided the best communication and service I’ve ever received in purchasing a vehicle. Rob made it a priority to make sure the best service was provided. I purchased a Macan for my wife and a Cayenne for me and we’re so happy that we chose to go with Porsche of riverside and that Rob was our sales rep. Also want to show appreciation for the sales manager Eric and his great finance team for all their hard work making sure the numbers were perfect for me! Once again, thank you for everything. I promise to send all my Porsche referrals to Rob and Eric!

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.

On November 25th I went to the Mercedes on Ontario, and was looking to buy an electric car around 7pm in the evening, I was looking at the EQB 350 when this very nice sales representative Abel Vargas helped us and was very nice and interactive explained to us what was good about the electric vehicles, at the end of the point of buying the EQB 350 the transaction at around 2am Black Friday after hours but I will like to mention excellent and outstanding sales person human being his name is fadi batarni I had a situation where I had to call him, a couple days after but was out of town but still answered right away, like always nice friendly and helpful manner, and I really appreciate the help and appreciate the huge help on purchasing my EQB 350 Thank you much guys I really like my 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

We recently acquired a 2025 MB 450 GLEe from Walter’s with the help of Christian Aparicio. We our longtime MB owners so it’s a high bar with us but Christian exceeded all expectations. We couldn’t be happier and will certainly contact him the next time we need a MB. Thank you Christian!

Great buying experience. I did take the car (BMW) to a BMW dealership for a concern I had with the car I bought at CarMax. They found something so then I took it back to CarMax to have it fixed (5-day money back guarantee and 30-day warranty) and CarMax took care of it at no cost and without any questions.

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.

Although the car we wanted didnt work out, the customer service was excellent. MARCUS is a STAR! He should be in management. I have brought many mercedes in the past. Carmax is turning the tide when it comes to purchasing vehicles. The best thing to do when you buy any car is to take it to another mechanic, and then bring it back to the place to be fixed within the warranty period. The Truck I purchased from them a year ago had a few issues but they did take care of it and I've not have any problems since. Carmax has set the bar high for purchasing returning and anything to do with cars. BRAVO!

WONDERFUL SERVICE.FRIENDLY AND VERY HELPFUL WE RECOMMEND THEM TO ANYONE WAITING TO PURCHASE A CAR !!!THANKS YOU LARRY AND NEAL :)

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!

I never write reviews…. BUT!!! A HUGE thanks to salesman JEFF! We appreciated his professionalism and passion to help us find our new car. Even after buying ours, he was so kind and quick to answer any of our questions. We are definitely recommending Jeff to our friends and families!

Ashley is top notch with knowledge and service and patience! Everyone at the dealership is helpful and accommodating. Thanks for everything, Ashley!

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.

recently visited Mercedes-Benz and had the pleasure of working with Mr. Jeff Tarin regarding the end of my lease end. I came in with a few preferences, which was to leaver MB & purchase a car with another Brand. I was uncertain about the most financially responsible path—whether to end my lease, purchase my current vehicle, or explore a new one. Jeff was incredibly mindful, honest, resourceful, and supportive throughout the entire process. His charismatic and empathetic approach immediately put me at ease. He took the time to thoroughly educate me on all available options, including the financial implications of each, while paying close attention to both my needs and my financial comfort. Although I ultimately decided to purchase a new vehicle, Jeff ensured that I felt confident, informed, and genuinely happy with my decision. His professionalism and care made a lasting impression, and I’m truly grateful for the time and attention he dedicated to assisting me. Thanks to Jeff’s exceptional service, I remain a proud and loyal Mercedes-Benz customer since 2017, and I look forward to returning to him for all future needs—both for myself and for my family and friends.

I had such a great experience at Mercedes-Benz of Riverside! Christian was incredibly helpful from start to finish—he really took the time to listen to what I was looking for and helped me find the exact C300 I had in mind. He was patient, knowledgeable, and made the whole process smooth and stress-free. I couldn’t be happier with my new car! I would definitely recommend Christian and this dealership to anyone in the market for a Mercedes.

Austin, Zach, and Jaime were exceptional , they got a a great deal would definitely recommend to family and friends!

Christian and Rob were the absolute best to work with at Walter’s Mercedes Riverside. They are very professional, honest and straightforward. So happy with our new purchase and the entire process.

“The entire car-buying process was smooth, efficient, and genuinely professional. From the initial inquiry to driving off the lot, every step was handled with clarity and care. The staff provided prompt updates, transparent information, and a streamlined workflow that made the experience stress-free. Overall, it was a well-organized and highly satisfying purchase.

I recently worked with [ Jeff ] to get my car, and the experience couldn’t have been better! They were professional, kind, and made the entire process smooth and stress-free. Highly recommend if you’re looking for someone who truly cares and goes the extra mile! 🙌🚗💫

This is the second Mercedes we have bought from Mercedes Benz of Ontario. The reason we have gone back is because of Michael Velasco, the sales associate. He is the best and most trusted person! We have had great experience with him.

Salesman Trey made the process easy and fast. I gave him the criteria I was looking for and he delivered even with my not so great credit. No hassle and no xx that I have gotten at other dealers.

This car met my needs of comfort, reliability, safety and moon roof! Also needed easy cruise control and big front compartment for purse. Like the memory seat also.
