Used Mercedes-Benz cars for sale near Ballwin, MO

Excellent experience all the way around! A special thanks to Brett Harness for following up with me and making my vehicle purchase happen even though I inquired about a different vehicle a month before. I was extremely pleased with everyone involved in the entire transaction at this dealership. Highly recommended!!

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!

I recently had the pleasure of working with Alex Hernandez during my car-buying process, and I couldn’t be happier with the experience. From the moment I walked in, Alex was friendly, professional, and genuinely interested in helping me find the right vehicle without any pressure or pushy sales tactics.

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

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.

I visited kind of skeptical because of bad used car experiences in the past . All I can say is WOW ! Very nice staff and the environment was very welcoming . The vehicle was better than expected and they worked with me on the price even when there wasn’t much to pick at . 5 Starts from 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.

Everyone has been very conscientious and courteous checking back with me to determine what I want and if I was aware of the age of the vehicle. They also informed me that their service department wanted to work on some issues with the car and that they would let me know what they did and what work they believe still needs to be completed.

I bought my E320 Wagon new in 1994. Currently, I have 248,000 miles logged. She burns NO oil and runs like new. Replacement parts? Thermostats, exhaust muffler, battery, shock absorbers, fan belt, transmission case gasket .... that's all. Since new I have spent less than $4000 on repairs .. but I did repaint for $5000. She's beautiful, comfortable and envied by all who sees her. In the past 27 years I have betrayed her twice by 1) buying a new 2012 Audi 6 Quattro, which I sold after one year and went back to my garaged e320 wagon and 2) was seduced by a sleek and fast 2004 BMW 540 wagon. After less than a year I sold the BMW and went back to the E320. I'm looking forward to the next 27 years and 500,000 miles with my E320 wagon. The best feature of my wagon is visibility. In the 80's and 90's good cars were built so you could see out of them. Today's new cars are built to hide the passengers from the outside world. And you cannot see out of the either.

Have purchased a lot of different cars at different dealers and the three I delt with there were great. Best experence ever. Derek , Adam, and Grant treated us like royalty. Purchased a 2025 Teguan for my grand daughter 11/14/25 and went back 11/15/25 and bought one for my wife. No presure sales and two the point , no haggle sales. I have probably purchased over 50 vehicles in my 78 year history and this is like sales should be. First time volkwagen purchases.

Hands down the finest automobile I have ever owned. Makes driving very enjoyable! Best ride and holds the road like no other. All wheel drive takes the pressure off winter driving. If you want a smooth ride, unbelievable acceleration and comfort then you should buy this car!

We bought a car this week from frank leta in ofallon. Ed was so helpful and knowledgeable. He answered all of our questions & was very thorough. This made the car buying experience less stressful. Would definitely go buy our next car from here with Ed! Hank and Ryan worked through the financial piece quickly and efficiently making this painless.

This is the 3rd vehicle I have purchased and currently leasing a new vehicle from Sapaugh. Rich Konold is the best sales consultant. He knows the vehicles and can help you match your wants/needs to the best vehicle for you, and get you the lowest price.

The CLE is the Perfect blend of luxury, style and performance. Only negative is premium fuel and higher insurance due to the automobile being a luxury sport coupe.

I discussed the purchase of a 2023 Mini Cooper "S" with salesman Dustin Summers. He was completely knowledgeable of all the features and details of the vehicle. He was always courteous and handled himself in a professional manner. I'm still debating on buying a vehicle, but if I decide to do so, it's back to Dustin Summers I go. Michael Deters

2014 Outback manual transmission and rear differential oil change was performed. It was done quickly.

This is our second GLC 300. We love the size and features for our needs (two people). Good mileage 27-29+ around town, 30-32 highway. Smooth ride, easy handling, and I think, nice styling. Newer models have larger screen and are more electronically controlled from the screen. Fields of Orange Park, Fl. has great Service, not cheap, "Mercedes" nuff said, but they will take care of you.

I had a great experiencing purchasing my car from BMW of West St. Louis. Dawn D. is an excellent person to work with. My purchase was remote and she acted as my eyes and ears, providing a trustworthy assessment of the vehicle I selected as if it were her own. She answered questions, made a video and was readily available to answer questions leading up to and through the purchasing process. The shipping process was seamless with a fast turnaround time. Armin H. was great on the purchasing side of the process. Extremely detailed and clear on cost, warranties, etc. All around great team to work with!

Had my 2012 750i serviced here a bunch of times and the staff was always great - will return!

nice car and no to expensive, comfortable, I can't explain how I like my new Mercedes Benz GLC 300 . My last car was very good , ut my new OMG......

Excellent experience - quick in and out w/ no surprises - Cody was very efficient and answered all questions. On the road in 35 minutes!

Been driving it for 3 years already. Great everyday car, I must admit. Unstated exterior styling versus the power train under the hood. Surprisingly, very good FC for despite the power. Mostly City driving averaging around 9km/l. Managed 13km/l on highway. Experienced a few issues with whining sound coming from engine that remained unresolved. Dealer changed front and rear axle, 2 drive rods, pneumatic suspension pump, wire harness and 48 Volt generator under warranty. These are certainly costly major parts. So, in terms of reliability, I would still rate it as 3, as no breakdown encountered till now.

Thank you Andy for taking the time with me in purchasing my new Sonata. Showing and telling me about the new features of my Sonata. Thank you also for your assistance in helping me with my accident. I will definitely recommend you to anyone who needs a new car. Also thank you Ryan for your assistance in handling my finances. You are both amazing and Awesome. Michael Simpson.

Best car I’ve ever owned , very comfortable and smooth ride , great on gas . Also as long you do the proper maintenance the car will last you , had for for 3 years no problems whatsoever. Also very spacious for size. So i definitely recommend this car to family friends or whoever looking for a nice car.

I felt they were honest 1st of all. Can't say that about very many dealerships. They gave the best trade-in value on my 2015 Tahoe (by far). I searched Missouri and Illinois for about 8 weeks and Sapaugh was the best experience Hands-Down. My ONLY fault with my whole experience was getting my paper work finished. It was a cash deal with a trade-in. NO financing needed. But it was a holiday weekend (01/02/2026) only one guy doing the paperwork processing instead of two. NOT a giant deal.

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.

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

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!

Easy to deal with. Texas was very knowledgeable and caring and listened to my needs. Fast easy process highly recommend! Great place to do business!

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

Ron, and the entire staff are first class! My wife and I flew down from Minneapolis. Ron picked us up at the airport. We took the vehicle for ride & within an hour and a half, we were on our way home. The smoothest transaction I've ever had buying a vehicle.

I love my GLB but two months and ten days, after the purchase, the engine needed a repair which was covered by the warranty. However, we were planning a lengthy trip and was thankful this did not occur while we were a few thousand miles from home. Me and My Mercedes are still trying to figure our communication out. I prefer Waz or Google Maps to their GPS system. Advance notifications of turns and such are better. Other than these issues I love driving her, Gilby.
