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

Best dealer
When you walk in its like seeing friends you haven't seen in years! Very friendly and they have patience which most places do not have. They made it easy picking a car and getting it!
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.

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.

easy transaction
I found a Ford F250 that had the options I was looking for on cars.com that Blasius of Middletown had in stock. Contacted Edwin (salesman) to confirm truck was still there and set up an appointment. The truck was detailed and ready to go when I arrived after a 3 hour drive to the dealership. I liked the truck, so I made the purchase. We negotiated a little on my trade and came to a deal we could both agree to. Overall had a smooth transaction.

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 !!!!
