2021 GLC300 4matic
I absolutely love this compact SUV! Coming from a Subaru Outback, this is light years above and beyond for same year. A quiet cabin is my top want for buying a car. This cabin is quiet and relaxing inside. I’m tall and there is plenty of room. The seats are incredible! Can’t wait to take it on the roads in winter.

Exceptional Comfort
I have had this vehicle for only one month so have not developed much experience with it. I did take it on a 1400 mile trip two days after purchase. It ran well, was very comfortable to drive, made for a very easy trip, was great on gas mileage, and it is very quiet inside the cabin. Seat comfort is exceptional and this, being our first experience with heated seats and steering wheel, was most enjoyable.

After looking for months at MINI dealership in the
After looking for months at MINI dealership in the tri-state area and as far as Pennsylvania looking for used car I found that South shore Mitsubishi had the best sales team. The entire staff and all people involved were very pleasant and professional very helpful and very energetic about every aspect of the process unlike other places that seem to be just non-interested trying to just blanket sales somehow. The team from top to bottom or excellent and I would not hesitate to recommend the steelership to anyone looking for a good car and professional and courteous people to deal with.

This was my third purchase, and once again, the team
This was my third purchase, and once again, the team exceeded my expectations. Shania, my salesperson, was fantastic—friendly, knowledgeable, and made the entire process smooth and stress-free. She took the time to understand what I needed and delivered with professionalism and genuine care. Khan, the sales manager, was equally impressive. He ensured the deal was fair and transparent, and you could tell he truly values long-term customer relationships over quick sales. Christiana, my finance manager, made the paperwork side of things a breeze. She explained everything clearly, found the best options for my situation, and treated me with respect and honesty throughout. It’s rare to find such a consistent and trustworthy team, and that’s why I keep coming back. Highly recommend all three!

Victor was super nice and professional and patient.
Victor was super nice and professional and patient. Knew much about the vehicle and its history and had maintenance documents ready to give me along with carfax. He also have the vehicle washed before my visit. He was very prepared. I did not buy on that day but I’m hoping to return should they agree to be flexible on their pricing. Seems like a well run dealership.

5 Stars!
5 Stars! I had an absolutely amazing experience buying my car from South Shore Mitsubishi with Ali! From the moment I walked in, Ali made the entire process smooth, stress-free, and genuinely enjoyable. He was knowledgeable, patient, and took the time to answer all my questions without any pressure. Ali listened to what I wanted, found the perfect car for me, and worked out a fantastic deal. It’s rare to find someone so dedicated to customer satisfaction, and Ali truly went above and beyond. I couldn’t be happier with my new car and the overall experience. If you’re in the market for a new vehicle, I highly recommend visiting South Shore Mitsubishi and asking for Ali — you won’t be disappointed!
