Used Mercedes-Benz C-Class for sale near Reston, VA under $20,000

Great and trustworthy team! This is my second vehicle purchased from them, and I couldn’t be happier. I’ve checked other options, but their prices are much better for the same mileage. Highly recommend these guys!”

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!

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?

Driving this car is so nice it rides so smooth and it has power too. Not to mention it looks really good. Never had a problem with it

Deondrea McLaurin was very helpful especially since our original salesperson, Nicholas disappeared. I was disappointed that I was not notified that he left the organization, as I was emailing him and not getting a response. I didn't know until the car came in. All in all, a good experience, but a little disorganized. Maybe because Nick left, all the paperwork had to be redone when we arrived because the car was supposed to be registered in our 2 names but was only done for one of us. There were many clerical errors, so it took a lot longer than expected. However, everyone was professional and kind. Also, we thought we would get a military rebate, but the small print is only if you finance through Toyota, who's rate is ridiculous. This should be noted in the headline. A bit of a bait and switch. Would use them again.

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.

It was a pleasure to be a customer at Mercedes-Benz of Alexandria. I have worked with and bought from different automobile dealerships over 20 years. I informed my sales manager, Mike Prati, who was AMG certified what I wanted from a car. He was the FIRST auto dealership manager who listened when I told him exactly what I wanted my car. Mr. Prati knew more about Mercedes than I could have read in magazines, Car Werk, Edmunds, YouTube etc. He explained the different variables of each model with and pros and cons. He directed me to the E class 450 sedan for a test drive. I personally could not have found the car without his background and experience. I bought the Mercedes pre-owned and certified. What made the dealership a phenomenal experience was how everyone listened and were respectful. Often, customers are talked to which happened at another dealership I walked out of two weeks prior. The goal: sell you something you don’t want. Not at the Mercedes-Benz of Alexandria. Later, I required work on the car. In lieu of calling the Service department I contacted Mike Prati. Who does that? I did. He immediately sent a tow truck, introduced me to a service assistant and I sat back as arrangements were made for a loaner. Mercedes-Benz of Alexandria was organized, cooperative and I had details regarding my car in less than 24 hours. The general manager, which people never see at dealership, called me. He wanted to be sure all departments were working together and I was satisfied. I actually think this dealership off of Pickett Rd in Alexandria has the finest employees. Great attitude. Thorough. Buying a Mercedes? I recommend Mike Prati to sell you one at MB of Alexandria.

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 cannot say enough about my experience dealing with Diamond Motorworks. My wife and I purchased our first automobile in IL (I'm a transplant) and I cannot say enough about the professionalism, kindness, and thorough handling of our transaction. Rami was a pleasure, answering all of our questions and concerns and wanting us to find the best fit for our needs. I believe in professional service and that is offered in spades at Diamond Motorworks. Our experience was so good that I have recommended 2 friends who have recently moved to IL to seek out Diamond Motorworks for their automobile needs. If you appreciate honest, no hassle and friendly service, this is your place. The vehicles are pristine, the service is top tier, and the transaction seamless. Thanks again Rami and Team!

Bought an amazing hybrid car with low mileage and a very competitive price from Motorcars of Gaithersburg. I had a great experience there. Ishmael's team was exceedingly professional and courteous. I walked around the showroom to see what else they have for sale, and saw a ton of solid cars in great condition. Would purchase a car from them again no questions asked.

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

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 🫶

I bought a car a couple years ago, Came back today to purchase another one. Truly a honorable dealership the first car i bought did not give me any issues and I loved the deal I got that’s why I am back today they treated me like family and took very good care of me.

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.

The dealership was very clean and organized. The car salesman Sean Furr was very professional and patient with me. My credit needs a little work before I can buy, but when I'm ready I'm going to Mr Furr

I have been the only owner of a 2016 c300 4matic sport for 9 years. I have owned the car since it was brand new in late 2015, and it has had only one issue during the duration of my ownership. The only issue I have had was that leaving it out in the extreme cold seemed to ruin the driver's LCD screen, whereby the screen would show random Chinese, Russian, Korean, and Arabic words before warming up and operating normally. Eventually, the screen quit altogether, but it was very easy to get a replacement. Other than that, it's mechanically extremely reliable, the styling keeps it relevant to today's designs, and the highway driving is impeccable. Performance is pretty mid-tier compared to BMW and Audi, but the engine doesn't have their issues. Overall, it's not a fast car, but it does inspire driving confidence when braking, even if the steering is somewhat lackluster compared to real sports cars. I take very good care of the interior, so there are no peeling issues, no warped wood, and no issues with the plastics, but the rubber seal in the moon roof has been a bit squeaky in certain temperatures, and the dealership said it would cost about $2k+ to take the sliding roof off, replace the rubber seal, and reinstall. The seats have held up very well, the alignment has never truly gone out of alignment, and the gearbox acts as if it's brand new. I do an oil and filter change every 4,000 to 6,000 miles, and I follow the regular dealer-recommended services. Mine just ticked over the 100k mile mark, and I know I'll keep it well taken care of for another 30k to 50k. I highly recommend this car; however, if you're looking for "value," please do not get this car thinking you will be able to afford it when something goes wrong. An average service will run you $250+ every 7k miles, and anything being replaced out of warranty will cost you north of $1,000.
