I recently purchased a GMC Acadia from Generation GMC, the salesperson was Chris Oliveto He was knowledgeable about all the different vehicles. He made me feel comfortable. The purchase was just very easy and smooth. I am very happy I took the ride over there. Everyone was kind and helpful. I had a great experience. I never felt pressured to make a purchase.

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.
