Used Mercedes-Benz cars for sale near Boxborough, MA

I have been servicing my cars with Smith for over 35 years. Always attentive to my needs. Simply the best for Sales, Parts and Service.

It’s been a great month of getting to know my new vehicle! I waited 12 weeks from the date of order to pick up my new 2023 GLC, and it was definitely worth the wait! I selected the Exclusive trim, Driver Assistance and AMG Line packages with several add-ons, and I could not be happier. My previous car was a fully loaded 2019 GLC 300, and it was unfortunately totaled in early February on a road trip. My first one was the favorite car I had ever owned and it kept us so safe during our accident, so I knew I wanted a second one. I did not realize I would have to wait so long to get a new one but I am happy I did not settle for anything else. The drive is sporty and smooth, and very quiet. It has a slight hesitation from a full stop. Once you take off it picks up very quickly and sport mode on the freeway is great. The upgraded electronics have been easy for me to understand after I read through the owners manual. One recommendation I have is to turn off the automatic speed change if you are using cruise control and happen to go through a construction zone. The cameras pick up the sign and slows the car down very quickly. I prefer to adjust to those situations manually. The car feels a bit bigger and is so attractive and comfortable. It feels much more luxurious than my 2019 did, and in my opinion the upgrades are worth the price. I absolutely love this car! Happy Shopping!

Greg Longo in service went above and beyond for me yesterday. Highly recommend Smith's friendly and knowledgeable staff. I will use Smith Motors for any warrantee work in the future.

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

We just bought a C-300 2024 from Smith Moters. Chris Walden was a super salesperson. Every thing he said was true. The car has everything we wanted+. the transaction was seamless. The financial end of the transaction was efficient. We would highly recommend Chris and Smith Moters.

I had an amazing experience at Audi Peabody. Ryan was amazing. We didn?t have a great experience at previous dealerships but he made sure to help us and change that. Everyone in the dealership was so kind to us. Would definitely recommend to other people!!

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...

Fabulous service; great and friendly customer service; knowledgeable staff who kept me informed during the service process; exceptional care is given to both customer and car.

I am now 3 years into ownership of a 2018 CLS 550, which I purchased new. The motivating factor to buy was that this was to be the last year that the big twin turbo V8 would be offered and it is a wonderful powerplant. I have not had one moment of regret since the day I picked my car up at the dealership and this includes MB service, which has been superb. I have done a few minor upgrades to the car, such as adding CarPlay, eliminating the engine shutoff feature, adding a rear spoiler and swapping out the standard front grill for an AMG vertical bar version. I haven't owned a car for 3 years+ in 50 years of driving, but every time I start to look at replacing my CLS, I can't find a vehicle that I would be satisfied with over the CLS, without spending well north of $100k. I love the power, the handling, the luxury features and the gorgeous lines of this car. In my opinion, at its current used car price, if you could find a 2015-2018 model year, (pretty much the same car) with low mileage, its one of the best used cars available. Strongly recommend.
