I Love our new GMC Terrain… We had an awesome experience buying our car. The car was better than what I thought it would be!! Inside, It has great space.

Robert was terrific. Knew his stuff made it easy. Was expecting fees and nonsense but he made it happen

I have had many Jeeps, when they stopped making the Cherokee I was at a loss until I came upon the GMC Terrain and so happy I did. Great style, performance handles great, many exceptional features, I spend a lot of time driving and never feel like it is tiring, lots of room in cabin and the cargo area. I have a new favorite, and it is the Terrain

Only thing I have to say is I wish I had purchased my Sierra truck from this dealership. I drove pass my purchase dealership just to do business with Rockville Center GMC Andy Melo and crew did a splendid job on getting me in and out and safely on my way.

I’m 56 and I’ve mostly owned trucks in my life. Out of the few cars that I’ve owned this 26 terrain elevation edition is the best car that I’ve owned. It’s comfortable and expensive gets good gas mileage plenty of room inside well designedand GMC has been a reliable brand for me over the years. I do recommend this car.

Car was serviced for an oil and filter change and a tire rotation. I was in and out in one hour. Very please with the overall service and fast turnaround.

This is a very beautifu vehicle, very dependable but the gas mileage could be better. With all of the new technology, it is somewhat difficult to remember all of the various control panel options. Also the owner’s manual is very skimpy.

Small detail that impressed me: when I picked up the car, they gave me floor mats as a gift. Maybe minor, but it showed real attention to detail.

Wilbur Pichardo was great! Efficient, Excellent communication skills and very professional. I Will definitely contact him again for his great service. Thank you

The service was fast and Jonathan, the seller explained me every detail of my vehicle. I definitely recommend Bomnin Nanuet and ask for Jonathan, he is the best!!

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!

Services were professional friendly and courteous. The service writer was informative and helpful with answering my questions. A clean comfortable environment. I would recommend this dealership to a friend.

A + all around went above and beyond to help me out very kind and helpful was in a serious pickle and everyone helped me out immensely

Thanks for the great work and fast turnaround. My advisor Andy was very communicative and transparent. I appreciate the loaner car which was very helpful to my family. I was impressed with all the work that was done to my car. My car feels like new again. I would definitely be back to this service GMC of Rockville Centre. Highly recommended!!

Always great customer service. Excellent waiting area with fresh coffee and a good choice of goodies while you wait! I love the new computer system showing your car while you wait

Jonathan c made it easy for me to buy my car with attention to detail!

I recently purchased a used vehicle from Petar Ardeljan and it was a pleasure. This dealership operates differently from most as they encompass a no pressure environment and are transparent throughout the process. I would definitely recommend.

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