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

Adrian took care of me throughout the entire service process. Set me up with a loaner, kept me updated with my vehicles repair status and got me in and out when my vehicle was ready.

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

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.

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.

Talked to Mark about getting a car and left with an electric car. Very satisfied, thank you Mark! Will recommend to anyone that needs to find a used car :)

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.

I've purchased many many new cars and I know what I expect out of a dealership and a sales person. And I am familiar with how to achieve and what is a fair deal. I was very very satisfied dealing with Marissa and this dealership. I've got a new Grand Cherokee Limited in my driveway and I know I've gotten a good deal on it. Good job Marissa. You know your stuff.

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.

Jose was a great salesman, I was able to find the right vehicle for me because of him. He was very nice respectful and easygoing. He made my car buying experience very nice and smooth.

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.

Quick and easy process. Everyone was really nice. Aaron went with me on my test ride and sold me on the Bronco Sport. Will definitely recommend to anyone looking for a new car.

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 had already leased an Infiniti car, and I had to return it next month, so I went to a dealership. The Infinity Manager was helpful, and the dealership staff also helped. And Today I re-lease a 2022 Qx60 full-option car. Dealer staff recommend this person (Sepan Zakarian) I recommend the Glendale dealership here.

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.

Bought a certified 2015 BMW 535. Ultra clean and low miles. Smooth transaction. Fair value for my trade in. Overall very pleased with staff and process.

So i went in already knowing what i wanted. Had my appointment already made and he was there waiting for me no issues. It was kind of strange to me how he didn’t know where the vehicles were so we had to go look for it. We walked for a bit then got into another vehicle to search for the vehicle. I think the lot and vehicle locations should be better situated. The buying process was easy and smooth. When the car was purchased i was waiting for a final cleaning and check of the car. This took forever. When i finally got the car. The inside of the windows were still dirty you can see the finger prints and the rear emblem had some chemical in it that oxidized the emblem. It took them a long time to seem like nothing had been done properly. I did appreciate the person helloing me to keep checking on me and letting me know the status instead of leaving me. The clean process and check process of the car needs to be better managed. It shouldn’t take that long for a half xxx job.

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!

This was the easiest purchase of a car that I've ever had! No haggling-just bought it! They bought mine and then I came back and bought one from them

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?

Easily the best car dealership I ever been to. It was like living the office tv show with all the charming and funny workers there! From Art, John and Armen they truly are the most interesting sales group in the world!

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.

They called us for our service that was covered by Toyota care. No issues and then recommended some additional items all Minor. This was our third visit all good. Thanks

BRANDT was amazing ! My niece took ownership of the 2020 Fiat Spider He was EPIC! Highly recommend AARON AUTO !! The whole Staff is a pleasure. Mahalo, MJ

I love driving this car!! It handles and performs amazing. The interior is beautiful and the sound system is excellent. I get excited every time I drive.

I just recently purchased a Mercedes M-Class from CarMax at Costa Mesa. I was ready with all the salesman pitches, haggling and general unplesantness that is associated with buying a car (paperwork, insurance, time, etc). But moment I walked in Kyle and Ron made me feel welcome and we were outta there with our new car in no time. We had little clerical error but they made sure that we had the that day to drive home with the best price possible (they gave the best trade-in value as well). Thanks CarMax.

Comfortable vehicle. Gas mileage is good and I use premium. No major issues thus far and anything that has happened like battery was covered under warranty.

Aaron helped my husband with his truck purchase. We are very happy that the process was very smooth.

Went from a Sahara Jeep Wrangler to this beauty & i Don’t regret it one bit. Amazing interior & exterior quality. Very clean & comfortable. I love it.

Leo at Pro X motors was amazing. I got a very good deal on a decent 2016 X3. Leo was a pleasure to work with, worked hard to get the deal done and I left with the car I wanted for a very good price. I would recommend Pro X Motors to anyone looking for a competitively pre-owned vehicle. Thank you very much!!

The confort and luxury speaks for it self. Nice and confortable ride. The car has the speed that I need. I’m in love gain !!!

This car meets all my needs and it had very low mileage and on top of that my note is very manageable to pay. T
