The car buying process at Habberstad BMW was rather
The car buying process at Habberstad BMW was rather straightforward. My salesperson, Paola, was very helpful in scheduling a visit to view the car and test drive, and answering any questions I had. Only once we were satisfied with the car did we move on to speaking about payment. Habberstad BMW didn't tack on any hidden fees, so taxes, titles, and document fees were the only additional costs, which they made transparent from the start. When it came to purchasing and picking up, the process was streamlined and was done in no more than one hour. After papers were signed, I was able to drive the car home and enjoy it. I would recommend Habberstad BMW to someone looking to buy a new or used car.

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.

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.

Jordanny was the service advisor who helped me, he was very helpful, kept me informed on my car.
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.

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

I recently purchased a pre-certified Mercedes-Benz from Victor Varga, and the experience exceeded my expectations. From the moment I walked into the dealership, Victor demonstrated professionalism, transparency, and a genuine passion for helping customers find the perfect vehicle. He provided detailed information about the car’s history, inspection process, and certification standards. Every question I had was answered thoroughly, making me feel confident in my purchase. The car itself was in immaculate condition, exactly as advertised, and came with a comprehensive warranty that added peace of mind. What stood out most was Victor’s dedication to customer service. He guided me through the financing process with clarity and ensured all paperwork was handled smoothly. Even after the sale, he followed up to make sure I was satisfied with my purchase. I highly recommend Victor Varga if you are looking for a trustworthy and knowledgeable professional to help you find a pre-certified Mercedes-Benz. His commitment to quality and customer satisfaction is unmatched.
