Used Cars for Sale in Quogue, NY

Bryan was attentive and excellent at making sure my car got repaired in time. He called and texted frequently with updates. The car came back fully clean, which was wonderful.

I recently had a very positive experience bringing in my car for service at Mercedes of Southampton. I needed a tire replaced and it was done quickly as they were able to get me in and one promptly. The staff was very friendly.

While shopping for either a new BMW440i or an Audi S5 my son(a two Mercedes owner) encouraged me to take a look at the new Mercedes E400 coupe. Best advice I ever got. Thanks to Gary Gentile at Southhampton MB he made this beautiful car possible. After purchasing the car, he put me in the hands of Nick Hatton (product specialist). Nick is an absolute whiz when it comes to explaining all the features on the 2018 E400 coupe. He explained everything in such a way that is was easy to understand. I'm sure he is the same way with all other models also. Can't say enough about Gary and his staff. Thanks to all. Bob V

Purchased a pre owned 2006 BMW 330ci I dealt with Sal who is an excellent sales person, and good humored, hard working representative. I must say that this was my best car shopping experience ever. The salesman was very informative and he was answering very question of ours patiently.

Outstanding service from this dealership.,quick efficient and pleasant through the maintenance service. Nice waiting room and will sure to be back. Loaner car was great.. Thank you

I just went in for service and to discuss replacing my 500sel. I learned Smitty was no longer there. What a horrific shock and disappointment! I live n 3 states and in 11 years he has been so professional, proficient and friendly. Never have I been so happy with my service, because of him , anywhere. I hope merced s of Southampton will bring him back and give him a raise! What a grave mistake Ever letting him go, I trusted him completely!!

Best Mercedes sevice by qualified techs. Couldn't be better.

I have used MBOSH for the past 10 years and will always buy my cars there. I have sent friends and family because they treat them honestly and always give them the best deal , they have become close friends with our family and they consistently deliver. It's worth the ride !!! Dr Avvento.

Andy and the service team are always courteous and professional. It's always a pleasure to do business with them!

Felicia was very pleasant and responsive. The dealership found the right used car for me. Joe, the manager, & Bruce and Mike were very friendly and helpful. They made the process comfortable and efficient.

The professionalism and courtesy was beyond exceptional. Showrooms were spotless. My point person was Justin Martinez he handled my trade in and putting in my new BMW. Joseph Saint-Val was my BMW genius. He spent over an hour sitting with me in my new car. He covered all the bases in acclimating me with my car. Joe was super professional and extremely knowledgeable. The last person I sat with was Helga Carroll who handled the financial segment.She was extremely knowledgeable and explained every little detail to me. All in all my experience at Competion BMW was perfect.

Excellent and efficient. Staff is friendly place is clean Car was cleaned after device and follow up was good. Will recommend to others looking forward to a long relationship

Would recommend the dealership to anyone I know who is looking for a BMW. The orientation was exceptional and look forward to working with the dealership through my experience with my New X4.

Mazen was great! He was a huge help and made the car buying process easy! Would deffinily reccommend to anyone looking for a new car

Mazen helped us get a car at this dealership and it was a great process all the way through. We got the car and color we wanted with all the features and I can't wait to start driving it. Very nice staff!

Mazen was great to work with, good character made me feel welcomed, doesn’t pressure you. Overall would buy from here again. Love my new truck

Mazen was a great salesperson. He took us to several lots and helped me find the car I was looking for. He got a detailed list of the features I needed and found one that fit. I test drove the Durango and took it home ! The buying process was smooth and all parties involved were very nice and kept me informed. Mazen then took the time to explain all the features of the car and what all the buttons do. I will certainly recommend family and friends to this dealership. I had a great experience !

Mazen great salesman helped me buy my car got a amazing deal, i love my new Cherokee Limited. i would recommend Mazen as your car salesman
