The car buying process can be hassled and stressful, but
The car buying process can be hassled and stressful, but I had the most pleasant and happy experience dealing with the team at Bridgeport BMW. If you’re looking for a prioritized experience vs predatory experience, then it is worth giving Bridgeport BMW your time and your business. Big thanks to Zashley, Paul and Charles, I appreciate your time, patience and accessibility. WJ

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.

Courtney was pleasant and knowledgeable while explaining
Courtney was pleasant and knowledgeable while explaining what would be done to my vehicle and the cost. She also told me what her mechanic recommended for the next visit. I have had the pleasure of having her take care of my last service appt but was unable to leave a review. Very happy with My KiA vehicle knowing that the service team is well trained and serves with attention to every detail.

I visited on the second day being opened and had a great experience in buying a 2022 Explorer and trading in a 2016. It was seamless. Had an issue with the new car that turned out to be a factory defect that they had Ford correct. All good. I’ll be back.
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.

Still the greatest
After the dealership was sold to Curry I suspected the quality of service would decline as it was the greatest and could only decline. It remains great. The service department and auto body shop are helpful and knowledgable.

Thank You!
It’s not often that we write a review about the people involved in selling something to us. But from start to finish every aspect of purchasing a car at Darcar in Greenwich was excellent. Our sales consultant,Ted,and sales manager Neerja, were very knowledgeable and highly professional. They listened to our endless questions and concerns and worked with us on finding the right car that fit our needs and budget - all without pressure. We were thrilled to drive off in our newly acquired Lexus. It’s everything we wanted!

Above and Beyond!!
I came to Mercedes-Benz of North Haven for a very specific Infiniti Q50. Mr. Don Shephard was appointed to me as my sales rep.We we went for my test drive…I was extremely transparent with Don and explained all things leading up to that moment. Good, bad , indifferent. Straight shooter as I called him, he returned the favor! Coming from previous experience in the business I knew what my deal could be possible, but didn’t know if the team would want to invest the time in off-brand car. Needless to to say, the finance guru… Danny and Don worked my deal relentlessly for days and didn’t give up on me! At no point did I feel that my treatment differed due to it being an off brand car. When I went to pick up my new car, they made me feel like they were genuinely happy for me. This dynamic duo was amazing and I would recommend this dealership without pause!!! Thanks again for everything D & D !!!!

This dealership was excellent! Our salesman Dominic was very profession, kind and welcoming. He helped me find a Toyota Highlander for my daughter for a great price. The financial agent Mr. Khan was also very helpful to find us the best interest rate possible. I would recommend this dealership to any of my friends.
