Used Mercedes-Benz C-Class for sale near Ayer, MA under $99,994

Superb experience purchasing my 2014 BMW X5D. The customer service was impeccable from the moment I walked in. I would recommend anyone to go here if you want to purchase a luxury used car! I wish I could give ten stars.

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...

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 🫶

Needed a newer car and was second to buy from my family. Awesome customer service and very helpful..Than You Jimmy Barros for your help with my Nissan Altima..

2013 C350 RWD, AMG Performance and Handling package. 108,000 miles. Bought this car in '16 with 40,000 Miles. It continues to serve me well. The one major problem has been an anti-theft ignition switch that only the dealer can fix. Cost 2k to fix. This is the only repaired I've needed. I have had all scheduled maintenance done, Runs quite well, and still has great performance. Handling is the best.

I bought my Fj cruiser 13 months ago. It was a great experience, from start to finish. Medi was great to deal with, worked with me to get me into the car. Connie was amazing with getting my financing in place. The whole process was quick and painless, which was unexpected, I was even able to drive it home the same day. The car is a beautiful bright red FJ, 2012 Trail teams edition, with 55k miles on it, and it still looks brand new. It is the best car I have ever owned, new or used. It has had no issues at all and runs like a dream. The 4x4 worked extremely well in the snow and on the beach this year. I would def recommend this dealership. A side note, A friend bought a 2011 FJ with 20,000 less miles, from a DIFFERENT dealership, for the same money, 1 month before I bought this, in comparing the undercarriages, hers has a concerning amount of rust, mine has almost none. Medi definitely goes for quality and has pride in the cars he sells. I would def work with Auto excellence group again.

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!

Awesome dealership to buy from.I live out of state bought and had a vehicle delivered it had some minor problems they were great at making sure all was taken care of. Absolutely recommend rt110auto to everyone.

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.

Excellent and on time service, Mike Robinson the service rep was very nice (as always), and a fine loaner vehicle

It was a great experience buying mt car at the dealership. The look and features of the car is what attracted me to it. Donte is a great salesman, he is very knowledgeable. He answered all my questions and show me how to use all the features that the car has.

I bought my car at this dealership a number of years ago..And coincidentally, I had a flat tire happen to me right around the corner from them. They replaced the two front tires (worn enough to merit requiring when changing one we needed to change the other). The process was quick. And while they needed to receive the right tires overnight they also cleaned the car quite thoroughly. Everyone was very nice and helpful.

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.

Sales rep was very good and informative. Knowledgeable about the cars I was interested in. Proper follow up and answered all of my questions and helped set up the cars technical items.

Super easy, straightforward experience - the price is the price, no annoying haggling etc and the car came in beautiful condition. Great experience!

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?

John and Kieran were exceptional throughout the entire transaction. John was a pure pleasure and professional. Our vehicle purchase process was truly the easiest and smoothest we ever experienced. We highly recommend John and his team.

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.

Buying a car from Mo was great. I do not like buying cars. I do not like the standard buying script. Thankfully, Mo talked me through the process. Showed me a coupe of vehicles and never pressured me to buy. With his assistance, I was able to make the buying decision that was best for me. In my experience, the prices were more than fair. The team was awesome and they continue to work with you after the sale closes. If you have researched your desired vehicle. Know the prices and what is available. Go see Mo. He probably has the car for you at a great price.

This car meets all my needs and it had very low mileage and on top of that my note is very manageable to pay. T

I had a wonderful experience with carmax in Westborough. Very friendly staff, very clean. They don't harass you. Upon entering the building, I was greeted and directed to the vehicles I was interested. I ventured the lot on my own and able to check out the vehicle. All the details were located on the window or they have touch screens with the info of the cars on the lots. Chris C was my sales person, he was very quick to respond to questions I had after I left the lot and also gave me detailed information about the cars I was interested in purchasing without haggling me to buy the more expensive car. When I had a question for him he would always answer it and send the brochure or the car detail info so I had it. The day I made my decision I was driving off the lot in a preowned vehicke within a few hours. I was extremely happy with my experience and would recommend Carmax in Westborough for anyone searching for a preowned vehicle. And i had been to other dealerships for test rides.

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!

Good place and good people to work with. Car was in great shape and process was clear.

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.

Great people great selection of vehicles. Highly recommend! Easy to work with. Financing and in state registration service provided.

My 2003 Mercedes C240 is the safest, most reliable, sleekest, brilliant, powerful, & comfortable car ever made because they can do anything a Japanese car can, but they also give the same luxury & safety that any car ever made can give. Built for high speed on the German Autobahn, these cars must provide safety at collision speeds of 120 miles per hour in Germany.

11/28/2025 I called Schneider at around 7:52 a.m. He then gave me the towing company’s number to arrange for the car to be towed at 8:39 a.m.
 At 9:29 a.m., Schneider called me to inform me that the tow truck had arrived at the dealership and that they were going to find out what happened with the power steering. He called me later and told me that the car was ready. Furthermore, he went the extra mile to check whether I was covered by my extended warranty. I had a great experience with Schneider. Kami P.

Stephen Leung at Mercedes-Benz of Boston is the finest sales consultant? I have had the privilege of working with either at this dealership or any dealership in past years. He is professional, extremely knowledgeable, articulate, and a pleasure to deal with it gives you the pluses and minuses and is completely honest. I highly recommend him.

Matt is Excellent. Outstanding customer service he is knowledgeable and quick and made the buying process a breaze. He went out of his way to make our experience the best it could be and stayed late to make sure my Wife could take hers home same day. I bought 2 cars in two separate trips on Saturday in the time it would take to buy one at other dealerships. This is my 4th car from AutoMax and have never had an issue with any of the vehicles or the experience. This is the place to go and I will be buying my next car there and asking for Matt.

Go to Michael Robinson for service. Absolutely professional and friendly can help you save a lot of trouble and cash

Mercedes-Benz was extremely helpful when it came to helping me with the purchase of my new C300. The facility was immaculate and team very accommodating.

I love driving this car!! It handles and performs amazing. The interior is beautiful and the sound system is excellent. I get excited every time I drive.

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
