Used Mercedes-Benz C-Class for sale near Affton, MO

I had the absolute best experience at AutoNation in St. Peters, MO. My salesperson, Anthony Smith, was upfront, knowledgeable, patient, and kind throughout the entire process. He never pushed me into anything—he made sure I was comfortable at every step and even gave me helpful tips on what to look for during a test drive. I later learned Anthony is somewhat of a local celebrity here in St. Louis, and it’s easy to see why. His approach and personality made the whole experience authentic and enjoyable. I also want to recognize Nate, the sales manager, who worked hard on my behalf to lock in the best deal for my situation. He truly went above and beyond to make sure everything lined up in my favor. And finally, Cameron in finance made the paperwork side of things stress-free. He explained warranties and add-ons so clearly that there was no need for pressure—the way he laid everything out spoke for itself. Because of his clarity, I was able to confidently choose what mattered most to me without feeling pushed. Altogether, this was hands-down the best car-buying experience I’ve ever had at a used car dealership. Anthony, Nate, and Cameron earned my trust, and I won’t hesitate to follow Anthony wherever he goes when I’m ready for another vehicle.

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.

When I purchased my dream car Genesis GV70 from this dealership I noticed how well kept the service area was. I only take my car here for service because it is professional, clean, organized and the staff is amazing. They do great work and often have you in and out in less time than expected. Josh and Brad have been so helpful. Their knowledge and experience is much appreciated.

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 🫶

Just bought (09/25) a 2010 MB C300 Luxury 4Matic. Car has 46,000 miles on the ODO. Local driving and 700 mile road trip so far. Fun to drive. Very comfortable and looks great. Gas mileage is not for the faint of heart, but it's a Sports Coupe ! So far, love this car.

I am visiting in St Louis and needed my 130K service. I called Suntrup West County Volvo and spoke with Greg in Service. When I arrived, he was accurate on him estimated time and came in just under quoted cost. Thank you!

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

Good and easy people to work. Duru was so helpful and kind. They help us to know everything we wanted to know and be safe on the road. Thank you 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!

I recently purchased a car from this dealership, and I cannot say enough how wonderful the experience was! From the moment I walked in, I was greeted with a warm and friendly welcome that immediately put me at ease. Every step of the process was smooth, straightforward, and stress-free. The customer service here is nothing short of fantastic. The staff was knowledgeable, patient, and truly seemed to care about helping me find the right vehicle. Special thanks to the general manager, Scott, who went above and beyond to make sure everything went as smoothly as possible. He made what can often be a stressful experience feel easy and enjoyable. I would highly recommend this dealership to my family and friends because I know they would have a great experience, just like I did.

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

It was a great experience! The salesman, Josh, was very knowledgeable and provided our family excellent service!

Amazing car, handles great , amazing build quality and lots of power and spunk. Highly recommend, best car I’ve ever owned and will be sad to see it go.

Prompt response to my interest. Was given several choices of a mini that fit my needs. Sam Hall, the salesman, was very helpful and put me in the car I love!

Tommy was very helpful and had prompt communication. He followed up and provided additional photos of vehicle.

GREAT VALUE - Bought the C300 4Matic Sport 4 years ago with 55k miles for my wife. Highly optioned with full leather, NAV, panorama roof, illuminated door sills, AMG wheels, blind spot indicator - nearly every option that the dealer did not know how to price! Very reliable and fun to drive on curvy roads. Only repairs are new battery and one tire pressure monitor. We follow the service guideline that the MB dealers suggest but usually at an independent ASE certified repair shop that works on German cars. Third Mercedes (all used) and one new 5-series that was highly unreliable - thankfully under warrant!

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.

Wonderful thank you Fred Willams and team for the amazing experience ❤️❤️,Im so greatful you guys are wonderful

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.

This review is for Jimmy, one of the sales associates here. I spoke with him about my options for trading my vehicle. He was very knowledgeable and helpful. Now that I know my options, I’m looking forward to working with him in the future!

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.

Best experience I've ever had buying a car. Great people to work with. Bob Reasoner and Cameron Brodeaux were great to work with. I will definitely buy from them again.

Very fast and luxurious I love the double sky roof and interior leather seats being lite so your seats dont get so hot in the summer Always buy the wheel and tire package its well worth it with all the pot holes and construction here in San Antonio you will definitely use it mutiple times!
