"Stamford Dealership is very professional from start to
"Stamford Dealership is very professional from start to finish. When I first visited their website, I noticed their high star rating, and now I can confidently say they truly live up to it! From the moment I call in, Sergio was welcoming, knowledgeable, and attentive to my needs. Sergio in sales made the car-buying process smooth and stress-free, answering all my questions with patience and expertise. Parker in service was equally fantastic, ensuring everything was in top shape and addressing any concerns with great attention to detail. The selection of vehicles was impressive, and the overall quality of service exceeded my expectations. I highly recommend Stamford Dealership to anyone looking for a smooth and hassle-free car-buying experience!"

I visited on the second day being opened and had a great experience in buying a 2022 Explorer and trading in a 2016. It was seamless. Had an issue with the new car that turned out to be a factory defect that they had Ford correct. All good. I’ll be back.

Wow what a complete difference in professional service
Wow what a complete difference in professional service from Generation GMC in Sayville compared from King O'Rourke in Smithtown. Service department is amazing. They send you a video from the mechanic going over all the concerns that you have any what they found. I was constantly being told my oul leak was a seel. Thanks to Generation GMC they took the time to find the real cause and it's going to take a week to fix. Thank God had the issues at King O'Rourke otherwise I wouldn't have found an amazing dealership. Especially Thanks to Maria for keeping me updated.

I recommend Stevens 112 Ford. Look up Carmine.
Excellent experience buying a 2020 Ford Expedition Limited MAX SUV because my salesperson, Carmine Randello was honest and helpful rather than pushy. Carmine had a way of making me want the car without trying to make me want it.
