Used Mercedes-Benz C-Class for sale near Rancho Cucamonga, CA under $899,990

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.

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.

Rodney was excellent easy process not pushy friendly knowledgeable very knowledgeable, the 25 words is giving a reason for someone to op out from leaving a review,

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.

Mercedes really are The Best!! Everything is Too Notch! The performance and gas mileage are great! Buy one whenever you can! There will be no regrets

Everyone at Car Castle is wonderful including everyone in Management. Eddie in management was wonderful and assisted us with all the process. Come see them you won't be disappointed! 👍

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?

The tr at house imports was amazing every step of the way , making the buying experience very easy and spent quality time making sure I was pleased with the process

Not happy with the degree of energy some employees/ sales people were and most likely won’t come back or recommended Although Dom Was excellent With his communication and care He was one of the only one here with people skills

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.

Well, our experience with Tony was Fantastic! We found a car on the internet that we wanted and proceeded to go out there to purchase. Upon our arrival, Tony greeted us without delay and processed our request. We were out of the dealership within 1.5 hours, now that's a record! He got us our approval in a timely manner and it was all good!!! I would definitely work with them again. Now about the markup, it seems all the dealerships mark up and in order to stay in business so I don't worry too much. Plus the fact the car we purchased was in pristine condition with low miles it was worth the markup and the drive. I am a satisified!

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.

Process is simple, prices reasonable, very good customer service. Overall good experience. Been customer with this dealer for over 20 years, always happy with whatever provided

i greatly appreciate diamond auto for helping me buy my car ,they were very very helpful with the process ,i will defiantly return in the future

Let me start with the c300 4MATIC is amazing has enough power to feel it and does good on gas I’ve owned mine since 2020 and have aftermarket parts on it and hasn’t gave me a not one big issue love this car 🫶

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.

We purchased a pre-owned 2017 Corvette Stingray Z51 from Mercedes-Benz of Foothill Ranch, and the experience was outstanding from start to finish. MB of FH provided a detailed pre-owned reconditioning summary along with the vehicle’s CARFAX, so we had complete confidence in the history and that everything had been thoroughly checked and serviced. Our Sales Professional, Conrad Cave, made the entire process smooth and stress-free. He was upfront, transparent, and answered all of our questions without any pressure. The Stingray was in excellent condition—exactly as described—and we couldn’t be happier with our purchase. We highly recommend Mercedes-Benz of Foothill Ranch and Conrad Cave if you’re looking for a quality vehicle and a top-notch buying experience.

I just bought my new 2026 Mercedes-Benz GLE 350 from Mercedes-Benz of Foothill Ranch, and the experience was amazing! Sean Roslon made everything smooth, stress-free, and enjoyable from start to finish. The whole team was friendly, the dealership is beautiful, and they even have an awesome coffee machine that makes the wait way better! I absolutely love my new car and highly recommend Sean and the Foothill Ranch team!

Still reviewing them have had good contact so far. They were great about bringing my other vehicle to my home.

2012 C250 Coupe summer 2014 CPO purchase. Odometer read 23000 mile as I wrote a check for $2500. Now at 42,000 miles this beautiful Iridium Silver coupe has one repair issue (ESL) It's the best looking car I've ever owned. An 850 mile round trip to AZ - mostly interstate - showed 35 MPG. I rarely push the turbo 4 - - - but when I do - the car responds in a - at least to me - a satisfying manner! In addition to decent highway fuel economy and adequate low end torque the car is just plain gorgeous - inside and out.

“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 came back for a second time buying a new car. Really great communication. The service provided is top notch. Thank you Bo and the team!

Every one who we talk to in the buying process was great ! Definitely will be back soon Thank you

Ryan truly did his best to work with me, because of Ryan I would definitely go back to this dealership and purchase another vehicle. He truly did his best to keep me happy with the amount of my trade in and with the amount of the purchase price of the vehicle I purchased from him. Met my payment at what I was looking to pay , he truly made me and my 2 boys feel welcomed and I truly appreciate you Ryan for all of our deal. Thank you

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.
