Used Mercedes-Benz S-Class for sale near Brookline, MA under $40,000

I bought a 2011 Chevy Suburban. Liam and John were fantastic. Amazing is an understatement. I did not know there are actually car dealerships anymore that go this above and beyond and as pleasurable to deal with. A+++++++++

Purchased an used bmw 328i, was super well maintained, got all of the paperwork that I asked for plus more. Great customer service and work ethic. Fully recommend this dealership, reliable and trustworthy.

We bought a 2013 BMW 328XI back in November. We love the car and the whole buying experience from start to finish. They went above and beyond for us.

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.

Bought my 2nd BMW from avon auto brokers, they got me a great finance rate/ and the staff was amazing. they alway have a great inventory of vehicles.

Robert was great through the car buying process. I bought an x5 and did an inspection . Robert made sure everyone from the inspection was fixed. So great to experience! Thanks

The whole experience was very positive. All the people were friendly and professional. Have had the car now over a week. It’s everything that I hoped it would be.

I had an exceptional experience purchasing a vehicle from Highline Group. Upon expressing interest in a test drive, Sales Manager Ted promptly contacted me to arrange the appointment. During the test drive, Salesperson Robert exhibited remarkable enthusiasm and provided a comprehensive overview of the vehicle’s features, addressing all of my questions and concerns. The vehicle was in impeccable condition, as Robert explained that Highline Group maintains an in-house service facility to ensure rigorous quality control. The dealership’s showroom was impressively stocked with a diverse collection of Ferrari, Ducati, and other high-performance vehicles. I promptly finalized the purchase, secured by Highline Group’s competitive loan rate that surpassed offerings from other institutions. I collected the vehicle within one week and have been thoroughly satisfied with the experience. I look forward to returning for future purchases and will confidently recommend this dealership to my associates.

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.

I had the pleasure of meating a sales rep named manny and he delivered just what i needed i was satisfied thanx msnny 5 stars!

I bought a 2014 Porsche Cayenne last year of them car still runs phenomenal. No complaints on my side super quick super nice no tricks no hidden bull Just make sure you check it before you buy it thoroughly. You should be good. These guys are great thanks again guys for the purchase.

Their customer service is very extremely good. Doug and Andre helped me and they are very professional.

Felt a bit like a fish out of water when buying a GMC Sierra among the Maserati, AMGs and Austen Martins, but Medi treated me like someone buying any one of those beautiful vehicles. My buying experience at Auto Excellent Group was probably the least pressured of all the cars I've purchased over 4 decades, as in no pressure at all. It was an easy going, informative, professional, and very friendly fun experience. Medi made sure I understood all new aspects and details of my new vehicle, right down to tire pressure readings and air pressure adjustments. I'm hoping to win the lottery so I can come back and purchase one of those Exotics. The LED pen is great too! Thanks Medi.

Medi was wonderful to work with. I will recommend him to anyone and everyone. He will be the first person I call for any future cars. Thank you Medi.

Great dealership. Brought my car in for 10k checkup. Alyssa was great, took care of everything including a brand new loaner car. Called me when ready and picked it up the next day cleaned and ready to go. Couldn’t be easier. Always enjoy stopping in and chatting with Armando and John.

It is nice dealing with true professionals that care about the customer experience. What a great team at Kelly Infiniti. My service rep was Pete and exceeded all my expectations. Always taking excellent care of the customer needs and paying attention to minor details that makes a great difference. Outstanding!!!
