I just purchased a Buick Encore from Buick GMC of Mahwah and I am thrilled all around. Gerald was patient, knowledgeable and so helpful. Jennifer, the business manager went out of her way to assist me through the buying process. The staff were all great and most importantly, I LOVE my new car!! Thanks for such a great experience.

Milea Service Manager Angelo contacted me, service was performed on my vehicle, dents were repaired. Problem was corrected satisfactory. Milea made good.

Very helpful service from Petar and extreme transparency very truthful and genuine 👏 looking forward to purchasing from this dealership

This dealer 100% is owed the most positive review ever! I never knew buying a car could be such an enjoyment! Start to finish best time ever! So happy! Thanks to Jaheim during initial phone shopping time, then meeting Moises sales and his manager Scott, who was so great and patient with me, to then getting to pleasure of meeting Jennifer finance manager who not only overcome credit obstacles she also made me feel like family after leaving her. Team you have there is unbelievable!

The experience and professionalism we received from Mark and the team at the Bomnin was amazing.

Great experience and service!! Prior to pickup everything was explained and verified in order to have a seamless delivery experience. Sharon was great at going over everything and Mike took it home with no hiccups. Definitely great customer service and experience!! Would recommend and buy another vehicle!

Pleasantly surprised that my car was repaired so quickly. Very nice and helpful Service Advisor Stan. I was quite shocked when he called to say it was ready.

Wow best experience ever! Hugh sales, Jennifer finance manager, and Scott sales manager were all so unbelievable! Thank you thank you!!!

Great dealership to work with. I had the pleasure of dealing with Zeeshan, Willie and Akbar and I have to say it was the best interaction I had in any car sales. They were professional, courteous and actually cared about what we wanted. Most importantly, they were honest. Communication was too notch and I was updated every step of the way by text or call. They went out of their way to make sure we had the best sales experience from beginning to end. The car itself is beautiful and they didn't cut any corners in the sale. I wouldn't hesitate to recommend them to any one and when I'm in the market again will definitely be a return customer.

They actually listen. No sales lines like “these won’t last” or “someone else is already interested.” Just respectful, pressure-free help. It made the process easy and comfortable.

It was quick recall service. Staff was hospitable. Provided good pick up rides from my work place. Dealership maintains a class of its own. A visit is worth.

They do everything from inspection to body work. When I go here service usually pretty fast. Andy Melo was my contact. He does a good job of explaining what?s going on with my truck?..

I came in with just a few questions, and they welcomed me like a regular. The manager walked me through the Terrain’s features while I sipped on coffee—no pressure, no sales pitch. Honestly felt more like chatting with friends than being at a dealership.

You can feel right away that the staff genuinely care. I came in solo, with no experience buying a car, and they walked me through my options patiently, explained everything, and never once pressured me. That kind of honesty and calm isn’t easy to find.
