Our experience there was great.
Our experience there was great. Everyone would cheerfully answer our questions. Our sales person Sheila Passmore really took a lot of time explaining the workings of the car. We still have questions, but Sheila said that we could bug her anytime (we will try not to). She is such a helpful person. The whole purchase was made easy and relaxed, no pressure and no rush at anytime. We have dealt with the Defouw dealership since 2014 and have always had really good sevice.
Never had one. Always wanted one and love it.
I love my Denali. Beautiful truck inside out. When I drive down the road all heads turn. I couldn't have made a better choice. That's Cortez for you good service.

Great friendly and knowledgeable staff.
Great friendly and knowledgeable staff. They were very helpful and they were very fair. Highly recommended.
Early to tell truck has less than 100 miles
Truck was bought specifically to our travel trailer. We have to wait for 1000 break in before we can tow the trailer. So far the truck is very quiet, smooth running, & comfortable to drive. We were pleasantly surprised at how much interior storage space is available. Having the bed steps before rear tires and in the bumper sides is very nice. Bed rails are even with my shoulders so the steps get used a lot.

Great experience working with Bita
The staff were very helpful. I did not want to buy new and they had the exact trucks I needed. I would recommend to anyone looking for reliable trucks without the spending top dollar for new.

Visited Grieco Honda, Johnston,RI, on Fri.
Visited Grieco Honda, Johnston,RI, on Fri. Mar.28, just to begin looking for a new vehicle. Didn’t plan to drive off the lot that day with a new vehicle, because “just looking “. Then we were introduced to Jacob Hammen. He put me right at ease by asking me what I was looking for in a vehicle, not what he wanted for me. He gave me the time to make a decision, narrowing it down to two cars of interest, which he then allowed us to test drive. Fell in love with a Honda Accord. From there, Jacob went above and beyond to present a deal that we were very comfortable with. While he was putting everything in motion for us, he also took the time to make sure we were comfortable in our wait for all the proper paperwork to be completed….asking if we wanted, or needed, a beverage, or snack. Was so pleased with Jacob’s professionalism and knowledge….would not hesitate to come back and see him, or recommend him. Great job, Jacob!!

Sebastian was very helpful and after some negotiation we settled on a price we both agreed on. I had to drive almost 3 hours to go get the truck from him and I’d do it again any day. If you’re buying a vehicle from Greco Ford ask for Sebastian because he topped my diesel off and detailed it for me. Great experience 10/10.
