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

Brought a 2025 Bronco from them and Logan was great to work with. They got me the number I was looking for and walked out with a new Bronco!

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.

Amazing service. Quick and easy and professional. The total process took about 1 hour. Couldn't be happier with 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?

The way car buying should be!

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...

Taylor was a great saleswoman! She communicated clearly and frequently with us, and we found a perfect starter car for our son!

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.

The sales associate (Siwan) was very kind and friendly. I was a little nervous considering this was my first car buying experience, but with the help of my parents and the Siwan, all of that nervousness went away! Siwan was awesome and helped me with everything along the way!

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.

Just bought a 2025 KIA Telluride from Grant a great sales representative it’s my third car from Grant and this new car we bought we love it Fred

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.

The service was amazing! I highly recommend buying a vehicle from SMH Auto Sales! Jim Gladhill was the salesman who was very professional and helpful with buying the new car.

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 🫶

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

We had an excellent experience with the repair of our Volvo. Andre is always very responsive. He even arranged for a loaner vehicle at short notice.

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 !!!

Chris D'allessandro is a fckn magician. If you live in or anywhere near Maryland, & have bad or no credit at all. Call Carmax & ask for this dude.. YOU'LL THANK ME LATER.

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.

We got helped by Taylor and she was wonderful. I knew the car I wanted and she greeted me at the door with the keys for it in hand. Very nice, and efficient!

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

The employees are friendly and courteous. They try to make sure you are comfortable in this environment. They explain what work has to be performed. They do not try to get you to do unnecessary work. I was greeted by two smiling faces. Lynese Hutchinson took responsibility for my car. She kept me updated via text message. My questions were answered immediately.

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.

Carmax is by far the best company that will go the extra mile to help you reach your Hope's and dreams and they did. Thank you.

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.

Precise and to the point. Presented themselves well . However, no deal was to be made.

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.

Hypiatia was a life saver , got me a great deal even with not so good credit on the car I wanted! Made the process easy and I ended up with a great car ! 10/10 Highly Recommended

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!

Our salesman was Eddy and I cannot say enough! He was friendly, very knowledgeable about all of the cars we looked at and was not pushy at all. I ended up driving away with a new car and I couldn’t be happier! Thanks Eddy for a great car buying experience! I will definitely be telling all my friends to go see you when they are buying their next car.

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!

I am buying a used car after 8 years, and this was great experience. No haggle is what I care. I was not forced to buy GAP insurance or anything else. The only complaint is, the lady taking down payment at the cashier was hesitant to tell me the details of the transactions before making a payment and showing attitude, but everyone else was great. I highly recommend this carmax.

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

The team at Carmax Gaithersburg was amazing! So appreciate their patience, attentiveness, and professionalism! Great job!

This car met all of my expectations. This car is very reliable. All of the features are great. Love the color. Smooth ride on the road

Purchased a vehicle with ease. Certainly a place where I would purchase again. Friendly staff. Showed up an hour early for an appointment, and was taken care of right away. The process was straightforward without any bumps. Was treated top-notch

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.

I am still driving this car after 11 years. I spent about $2200 on average per year to fix or replace this thing. Still drives good, far more expensive that I would like it to be.
