Used Mercedes-Benz C-Class for sale near Darnestown, MD under $30,000

Good cars for good prices love my car i will be back for another car

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

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

Salesman (kash) was good. I didn?t feel pressured, environment was pleasant, my trade in was fairly priced. I will go back to the dame dealership in future when they have the type of car I want.

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.

Overall, I had a good experience with Auto Expo. I scheduled a test drive the day prior, and they had the car waiting out front for me when I got there. After the test drive, I was allowed to make a thorough inspection of the car and Abraham answered all of my questions and critiques on the car. I pointed out some issues with the car--for example, the trunk cargo mat was gone--and they proceeded to fix the issues where possible. The lot and the office are both small and cramped. Parking and moving around felt a bit awkward, and there was clutter that needs to go. In the end though, that's not a big deal though, as I care most about the car and the price I'm paying for it. Speaking of price, negotiations with Auto Expo were the most cordial of the places I visited that day, which was appreciated given how all negotiations are at least a little bit awkward. Again, I had a positive experience.

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.

I received a prompt reply regarding all information I requested regarding the car I was seriously interested in buying.

This has been by far the best car I’ve owned. I use Yokahama Avid Ascend tires and have been able to travel in any weather in this car. I had a tire blow out (after 76k miles) and the car never wavered once!! During an extremely busy year I kept forgetting or not being able to take it in for service and went 40k miles over the oil change, that was 100k mikes ago and it’s still running great!! In addition to the comfort and sporty look, it’s fast, fun and easy to drive. The only downfall being the expense of services and repairs, which is to be expected out of a quality, import car. I’ve been able to do a lot of the work outside of the dealerships and found that Ebay, FCP Euro and Rock Auto have had anything I’ve needed for repairs and services. I would recommend this car hands down to anyone, any time.

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.

I bought a car from them in August 2020 and was very happy with them in many ways. They were very straight forward and very confident about their car. They were very helpful and nice at the same time not only the price was fair but, they even gave me a discount as well. They seemed to be more interested in keeping customer satisfied than making more money. I would recommend them to anybody who is looking for a used car. Gholam MD.

I've had this car since 2012. Bought demo from a dealer. Reliability is excellent. After 120000 miles I've only had to replace the timing chain and gears, thermostat, front brakes and tires. Drives like a dream. None of my past GM vehicles would even come close to being this reliable.

The website was accurate and the employees were helpful. I found exactly what I was looking for.

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.

Jimmy at Carmart. was absolutely terrific. Out of the dozens of times I have bought a car from anyone this was the most smoothest ever one that I felt no unease about. Jimmy took care of a problem after the sale with no hassles even picked up and delivered my wife while his crew worked on the car. By far the best dealership I have ever worked with. If you’re looking for an honest dealership that you don’t feel will cheat you this is the one.

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...

AWESOME DEALERSHIP AND STAFF❣️ GREAT SELECTIONS 2 CHOOSE FROM🚘🚙 THANK U 4 MY NEW SUV🚙🤍💃🏽🥳🎉

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 !!!

1st Dealer I find with all info online and low fee. They drop my car to my house with no extra fee. Thank you

Bought it as certified used with 14,000: miles and 3 years old. Absolutely love the car. Now have 60,00 miles on it. Only cost other than routine maintenance has been tires. One dislike is run flat tires. They make no sense. Also did not like the engine shut down at stops ostensibly to save fuel, but I was able to over ride that. And I bought a spare tire and wheel another major issue for me is you cand buy a trailer hitch for a C 400. You can for other C cars, but not the 400.

They were very patient with me. I changed my mind on what car I wanted like 5 times. In the end I walked away with the car I wanted

Great to purchase a vehicle that is ready for the road no repairs needed. tires and breaks in good shape. Delivery service available. The financing is painless.

I post a review on June 7 2025 and today July 26, 2025 we had meeting with the manager James and he settled the price issue we had with the purchase of Honda civic 2016. Thank you James

2017 Mercedes c300...This car met all my needs. Great interior and exterior, low mileage. Tires are also in great condition. I will use this car for my everyday use. Great gas mileage.

Great service, solid prices, clean, fast, easy, simple, fair, need to reach 15 word minimum

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!

This car has been absolutely amazing. No issues with it what so ever only regular maintenance like oil changes and replacing tires. Bought the car 6 years ago with 32,000 miles or so on it and now have 210,000 give or take. I’ve used it to commute, to travel, to run errands, anything you could imagine. Wouldn’t trade this car for the world. It drives incredibly, performes great, and is beyond reliable, not to mention it’s a good looking car too.

They were super helpful and low pressure, and the car is exactly what we need. The financing was easy and they can work with folks with a lower credit score. They have a large inventory from which to choose with odometer readings under 90,000, and the car came professionally detailed. My husband and I are very happy with this purchase!

This car has been the best and most reliable car I have ever owned. My wife got a new car for her birthday or I would not be selling it now.

I found the sales experience to be excellent. Both my sales person and sales manager were engaging, helpful and honest in their approach. The sales process itself was very quick and with the professionalism of the business manager, both painless and enjoyable. I was very happy with the entire process!

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!
