Used Mercedes-Benz cars for sale near Brentwood, NH under $20,000

Overall satisfied with the service, not to impressed that my Jeep broke down and was out off service for a week.

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.

Got a truck from them bought running boards for the pickup but couldn’t put them on cuz running boards were rotted so called Tim’s an they said bring the truck down an fixed the issue thank you

I purchased a 2017 GLE 350 with 27,000 miles on it the SUV is a dream come true, you can't get a more quiet or smoother ride in an SUV. Has every option in the you can get even self parking. Love the color combination white exterior and cashmere interior, I have the original window sticker and sales receipt the car sold out the door includes tax and discounts dealer prep for $64,000.00

We Purchased our third BMW form TMC late this fall. Both Rick and Gregg helped us and they were both excellent. Great product knowledge and these cars have lots of options! We live in western NH so we would not made the drive unless the service and selection were the tops!

Absolutely a delightful to drive, superb quality interior and excellent drive! I am very pleased with my 2016 Mercedes Benz E350 4Matic! Great info center!

I love my Mercedes It has special powers And a 4 liter engine. What a wonderful easy car purchase These gentleman are spot on with their cars They care It shows

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 recently bought a beautiful 2012 Dodge 1500 Ram I couldn't be happier with! I drove 2hrs to see it and it was more beautiful than it looked in the pictures. I worked with Mike, Dillon and Sasha on my purchase thru emails and phone and they were awesome. It was well worth the 2hr drives. On purchase day the process was fast friendly and professional. A great place to purchase a good clean used vehicle! I definitely recommend this dealership to family and friends. 👍☆☆☆☆☆☆

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.

I recently bought a Lexus GS 350 here and it was an absolute pleasure. Mike Walker is a consummate professional who listens to what you want rather than making a lot of noise. No undercoating; no extended warranties, no bullish… Sasha is also terrific if you need financing as well. Go see Mike. Eric S-Beverly

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.

Very professional experience. Kara was outstanding. Recommend others to use the dealership. Very satisfied. Smooth and seamless process. Felt like a priority and management supportive.

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

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..

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.

2002 E 430 4matic I've owned it since 2016 with 110000 miles on it. Now nearing 185000 miles. Best car I've ever owned. Fixed a leaky seal and replaced the PSE and tires. This car has power and can corner well. It's solid and quiet.

We were very lucky to come across Alliance Motor Group. Our 08 Ford Escape finally began to kick the bucket. As a two car family it was essential that we find a new vehicle fast & one that was safe for our young family. We came across Alliance Motor Group & Mike Walker (salesman). He quickly was able to help us find the car we were looking for, setup a nice test drive, and then got our purchase done within days. If you're in need of a new or used car this is the place to go. The owner was friendly, met me as we picked up the car, and has available even after we were done. Truly a 5 star 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?

I thought my experience at Alliance was great. The sales people were nice and helpful. The car I bought was extremely clean, it looks like a brand new vehicle. I hope I don't need another car any time soon, but I would shop there again.

We have owned our 2015 for two years now - got her used from a family member with about 55k miles. The car is comfortable, fast, huge, and gets great mileage for its size and weight - about 21mpg with a mix of city of highway miles and I'm shocked by that. This is the year they put the 3.0 liter twin turbo V6 in the GL450 - not sure what other years they did, but I highly recommend this engine. V6's are often marketed as having V8 power when they really don't, but this one absolutely has V8 power. It even sounds like a V8. You can certainly feel the car's heft on turns in country roads, but it weighs basically 3 tons fully loaded. It feels very safe and is super quiet inside - build quality is superb. It feels like a fast, luxury tank. I love it and I'm going to drive it as long as I possibly can.

I recently bought a Certified Pre-Owned Mercedes-Benz E 450 at Mercedes-Benz of Portsmouth. It was a very nice experience working with Cynthia Acorace, my sales associate. When I picked up the car, they let me know that it was missing the key to the locking lug nuts, but they were ordering a new kit and would let me know when it was ready. Cynthia sent word to me that the kit came in and I could come at my convenience and a tech would change the locking lug nuts and give me the new key. I went in yesterday, and Cynthia took me to the service area where Cory Counsil was supervising the department. When Cynthia explained why we were there, Cory sighed and explained that there was a problem with the service software, and they had allowed all the techs to go home early. Cynthia escorted me to the customer lounge where I had a complimentary cup of fresh brewed coffee, and began to browse through the gift area where they sell Mercedes logo shirts, key chains, and coffee mugs. After a moment, I looked out the window and saw that Cory himself was changing my locking lug nuts. Within moments, Cory had gone the extra mile, and, even though there were no techs working, he took care of things personally and came to find me, telling me it was ready. Cynthia, caught up with me before I left and was concerned to see if I had any questions about the car, now that I had been driving for the first week after buying it. I did have some questions about the automated parking features and how to use the shift paddles. At that point, another sales associate, Ben Lamont, came over and gave me an encyclopedic dissertation on how the parking assist feature worked, and then he showed me how I could easily get in and out of manual mode with the shift paddles. Ben's enthusiasm for Mercedes automobiles was evident, and he made me really feel good about my purchase. From when I was first visiting the dealer, as an off the street shopper, browsing the inventory of cars, through the sales experience, and now as a customer needing help, I have visited this dealership a half dozen times over a 3 to 4 week period. During all those visits, everyone has treated me like a VIP. I was never made to wait, and any concerns I had were taken seriously and addressed immediately. I would recommend this dealer to anyone in the market for an upscale car, and tell you to ask for Cynthia or Ben.

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

Peter Derby is worth his weight in gold. I live in France and he was brilliant, he sent me a picture of the parts to confirm the correct ones, arranged delivery to Portsmouth confirmed their arrival before charging me anything. Once paid ,confirmed that they were sent job done! All done in a calm professional maner. Perfect 11/10

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!

I just purchased a SUV here and the staff were great no pressure. I love the new vehicle I bought, and it just passed state inspection with no issues Thanks

This car is something I really love. It has so many built in features that are there to assist the driver and passengers, and provide comfort. It is also an impressively FAST car! I was out on an open highway years ago, and the more I stepped on the gas pedal, the faster the car "flew". It refused to level off at any maximum speed.

I have a SLK230 since 1999. Drove it from WA state to California on Highway 1 multiple times. I also drive it every weekend for trips to nearby towns and during the week to get a coffee. It is a great little car with a bit odd engine sound, but it has been going on without an issue forever.

Amazing experience. My fifth car bought at this dealership. Chris, the salesperson was very accommodating. They made the experience easy.Would buy a sixth car!

Very smooth ride. Lots of cool safety features. Good power. Good value for my money as I bought this as a CPO. Mercedes Benz financing made it easy to own.

Best experience ever. The entire purchase process from start to completion was 5 stars and the communication was excellent. The salesperson was excellent, business office was excellent!

Got my 2015 gla in 2016. Drove it from NJ to DC every week even in the middle of a blizzard.. I feel like it has a more agile power steering. It can fit it anywhere. The ride is smooth and quiet. It’s now 2025, what do you think? I got the mountain grey color. It still shines like new!

First time buying a car from them and I couldn?t be more impressed with how nice the sales people were, I will definitely be purchasing my next car through them,Service was great.

A prefect car. So luxurious! Very spacious, great size for family and friends. Very reliable. Would recommend to anyone looking for safety and style at the same time.

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.

I have owned my 2017 E 300 for 5 years. It has been the finest car I have ever own. It is enjoyable to drive. It's a baby S class. I searched and purchased the 2017 e300 with P3 package. The lane keeping assist is the most advance in 2017. The engine is a 4 cylinder but it handles like a V-6. This car is leader for luxury, driving and durability.

We have been working with Matt Chagnon for several years. This will be our 13th vehicle from Bonneville through Matt. We not only continue to buy from them but have sent our children to them as well. We always have our questions answered and know exactly what to expect, what price we will pay and no surprises. We will definitely continue to use Bonneville for all of our transportation needfs.

I love my car not only is it fast but it's conterable and stylish and dependable iv never had a car like this one before
