Used Mercedes-Benz S-Class for sale near Riverside, CA

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.

MBZ S-class always 5 ***** vehicle. The most luxurious , comfortable, car I ever drove . I highly recommend it . My old Mercedes S-class has 200,000 miles and not a single problem.

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!

Franklin is great. Thank you for your support help and patience with me. Love the car. At rides great. The paperwork and process was fast

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 picked up my S580 Lux-Line in Emerald Green over Sienna Brown, and I am absolutely thrilled with the purchase. I have owned five S-Class models since 2010, including this new one, and I can say this is the best iteration yet from an overall perspective. While I still think the W222 was the best-looking (especially my 2019 S560 with the refreshed look and AMG pack), this new one does not disappoint at all. The Emerald Green is stunning in the sunlight, my favorite color yet. And the interior is on another level from a luxury and tech standpoint. I loved the interiors of all the S-Class models I've owned, but this current one is my favorite. The seats are super supportive, and the vast amount of tech is amazing. The new infotainment screen takes time to learn and get used to, but I feel the "Hey, Mercedes" function makes doing small things like putting in a Navigation request easier than going through the main screen. From a driving perspective, the ride is the best yet, just like gliding on a cloud. I've been lucky to have driven Bentley's and Rolls-Royce's in my lifetime, and this ride is as close as I've seen the S-Class come to being even with those vehicles on this front. And, the V8 is plenty punchy when needed, so it can be a fun vehicle to take on windy roads if you so desire. Overall, a wonderful vehicle and a bargain when you compare it to the other super-luxury vehicles on sale. I'm looking forward to the next few years of owning such an awesome car.

Aaron has been very courteous and professional during my contact with the dealership. He's gone above and beyond in his approach to customer service.

Dollar for dollar this is the best car that money can buy. A 3 year old MB Certified car with around 30,000 miles is the way to go. The price will be about 50% of original MSRP so you save about $50,000. I suggest 4 MATIC and AMG trim package. I 've owned other MB's, high end Jaguars, BMW's, Volvo's, VW's and several American cars, new and used. This is the best.

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

This car should be classified as an “exotic”. The S550 Coupe is by far the best vehicle I’ve ever owned. Well, our 2008 S63 AMG was a monster, but very heavy. The ride is harsher than expected over rough roads, but it isn’t close to a deal killer. The interior is perfect, but the controls were clunky at first….until you get used to it.

Excellent car. I am driving S550 2015 for 6 years with no any mechanical problems, this car is soft driving and luxury finish and look.

Had really pleasant experience purchasing my daughter’s first car here! They have a very nice selection of inventory to choose from and their website is straight forward and give you lots of information to make an informed decision. Staff is very friendly and never once did we fell pressured. Highly recommend this dealership.

The entire process of working with Zora was incredibly communicative, accommodating, and easy. He even stayed late at the dealership since I had to fly in. He took good care of us and made sure the vehicle I purchased had everything I needed and did a double-check before we left the dealership. Thank you for everything!

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!

sale associates very helpful during whole process. very pleased with purchase and customer service. Second auto bought from carmax.

S450 is a great value. Plenty of power. Very comfortable. Quiet and smooth ride. Don't need the big engine. Would definitely buy again. Very dependable.

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

recently just bought a super low mileage 2006 S430 California one owner car, that had been pampered and garaged. Beautiful flawless interior, gorgeous exterior with AMG sport package and new tires. Car had around 87000 miles on it, so I didn't squabble over 10k price, it also had new tires. I own another 2009 S550 but couldn't resist buying this one as it was last year of the body style and this one had wonderful service records. Engine shifts perfectly, AC blows cold, fresh oil change, it is a really great car for the money and you simply cannot buy a car of this high quality for this amount of money.

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.

I have driven an S Class Mercedes since 1995. I have not owned anything else. This 2023 S 580 4matic is amazing. With four wheel steering, turns are tighter than you predict. The performance is more than I can handle today and more than adequate. Interior, comfort and exterior are all within my normal Mercedes expectations. After driving this vehicle for 30 years, I am not sure I can accept LESS. Most any vehicle is accepting LESS. I also own a 2020 Range Rover Sport supercharged V8. Just as impressive but not as comfortable. The S Class is what all other vehicle manufacturers are typically chasing to "meet". I have test driven many comparable cars, but none worth buying.

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

The 2007 S550 What is unique in design from its conception greatly because it was the changing of the S class design and body style, the size of the vehicle as well as a drastic change in the onboard computer and operating system win first premiered what the public have the opportunity to see was what would eventually become the release of the maybauc because this is a glimpse into the body style of what the maybauch would it look like?

It's an 2023 S-class Mercedes. That pretty much says it all. The fact the it is also a Plug in Hybrid just makes it even better. Plug in at home and you will hardly ever need to buy gas. Plus it is so smooth running on electric that you will love the car even more. Best one I have owned and I have been driving these since 1998.

Enjoyed my experience here at this dealership. Came out with a brand new car! Anthony was extremely helpful and guided us to find the car we were looking for.

Anthony sold me the 2020 Mazda 6. Super nice and very informative and fast too.

Excellent customer service, detailed oriented, honest deliver what they promised, a lot of selections very very low mileage like a a prenew

Very comfortable strong fancy and cool ! Perfect for family users! Big trunk comfort inside ! Black on black new tires new wheels just set up!

Great experience.. we had a little hiccup during the test drive but It was rectified and the sale was made .. they have quality high end cars and pleasant personnel. .. great experience again!

Highly recommend Mercedes Benz of Foothill Ranch! This dealer makes me feel comfortable since I step in, they had customer focused approach and an awesome coffee machine. Albert was extremely professional, patient, and transparent throughout the entire process. He helped me find the perfect used Honda CR-V at a very reasonable and fair price. The whole team made everything smooth and stress-free. If you're looking for great service, honest dealing, and good value, this is the place to buy your car. Thank you Albert and the team!
