Used Mercedes-Benz sedans for sale near Weldon Spring, 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.

Car is very reliable and have driven it on long trips. in the last few years mostly local driving. Its and expensive car and you really purchase It for its contort and safety. Service has been pretty good i have owned six Mercedes over the years

Ryan helped my daughter make her first adult car purchase. He went above and beyond to make the car buying experience a fantastic experience for her. Everyone there were so friendly and down to earth with easy going demeanors. I would recommend them to anyone purchasing a car!!

Amazing vehicle, but only buy new if you want the S63, the Maybach, or your just really rich, if not, then just wait 5 years, and get it for 70 grand! The value is so low because you can just wait for it to depreciate like crazy. But overall, this is an awesome car.

FANTASTIC Service dept. and the staff in parts and service are so easy to work with each time. Recommend to visit for sales and service.

I have driven an S Class Mercedes since 1995. I have not owned anything else. This 2023 S 580 4matic is amazing. With four wheel steering, turns are tighter than you predict. The performance is more than I can handle today and more than adequate. Interior, comfort and exterior are all within my normal Mercedes expectations. After driving this vehicle for 30 years, I am not sure I can accept LESS. Most any vehicle is accepting LESS. I also own a 2020 Range Rover Sport supercharged V8. Just as impressive but not as comfortable. The S Class is what all other vehicle manufacturers are typically chasing to "meet". I have test driven many comparable cars, but none worth buying.

Awesome experience. Cody was professional and easy to deal with. I came from about 45 miles away and he knew what time I would arrive to look at it and take it for a test drive. Cody was honest and very straightforward with me.

This car should be classified as an “exotic”. The S550 Coupe is by far the best vehicle I’ve ever owned. Well, our 2008 S63 AMG was a monster, but very heavy. The ride is harsher than expected over rough roads, but it isn’t close to a deal killer. The interior is perfect, but the controls were clunky at first….until you get used to it.

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

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 highly recommend Dean Team Hyundai and my salesman Milano very professional, and knowledgeable. Milan was patient and polite I got the car I wanted at the price I wanted

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!

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!

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.

I love to get my vehicles from Weber in Granite City. Kevin and Zac are the best ever. Not one time have they done me wrong. Kevin always makes sure he goes above and beyond to help me find exactly what I am looking for. Zac goes above and beyond to help me find the perfect lender for my needs. I would never chose anyone different. Thank you both for being there everytime I chose a new vehicle. You both are the best. I LOVE my 2026 Equinox!

Easy transaction and really appreciated the urgency that Tracey and Justin demonstrated. I can?t remember a car buying experience that didn?t take all day, so this was great.

Wonderful staff, easy to work with. Everyone was very knowledgeable and was able to answer all of my questions and concerns through the entire process.

The deal was great (financing, complimentary maintenance, discount). Willingness to find the right vehicle in another state. Friendly and professional experience. I would buy here again.

Excellent Service!!!! I love this place! Will definitely recommend to more customers! My car is one of a kind and definitely is unique to my personality! Mercedes is definitely hands down the best luxury car choice! Go get yours today!

The car buying process with Plaza Infiniti was amazing through the whole process. They were very accommodating with the whole process, even when purchasing from out-of-state. Barney makes you feel at peace with the selection process, and Rob is very knowledgeable and helps you to find the best deal when it comes to financials. Altogether was an amazing experience and I would recommend Plaza Infiniti to anyone looking for a new 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

On July 15, 2023 I purchased a new car from Dean Team Volkswagen in Kirkwood. Eddie was great to work with and made buying a new car painless. We were in and out in no time. Thank you Dean Team...awesome customer service, we will be back!

2014 CLS63 Type S. I’ve owned maybe 50 cars in my lifetime. Never a car like this. Bad to the core. (In a good way) The engine is second to none. The handling bests my mustang. The interior is clean, classy and feels quality. The car is fast. And I don’t mean hey look at me fast. I mean, hold on and maybe I should let off the throttle a bit, fast. No problems mechanically so far. But I am well aware of the potential cost of maintenance. That would be the only draw back. Very happy with this vehicle. Love the look. Love the feel. Love the power.

Matt is the kind of dealer you had back in the day. I enjoyed the short back and forth we had with numbers and the entire dealership left us with needing nothing, they took care of us further then we actually needed

Don Clayton was my guy and he?s zero pressure and knew his stuff. Made the whole process easy. Will always buy my Mercedes from this dealership.

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.
