The Ingersoll employees provide excellent and friendly
The Ingersoll employees provide excellent and friendly service as always whenever I go there for service or to purchase a new car. I highly recommend the dealership.
So far so good!
So far so good! This truck is the nicest truck I have ever driven. The stance, ride comfort and options are top notch. I went from a 2023 High Country that was having drive train issues but had all the creature comforts that you would expect in a top of the line truck. With the lack of confidence in that particular models 10 speed transmission issues, it became necessary to reestablish my confidence in my General Motors product.

I just purchased up a late model Pacifica.
I just purchased up a late model Pacifica. The transaction was professionally handled. There were no surprises. A hat tip to our salesman Julian and Ken in service, both customer focused. I particularly appreciate their followup communications. It does make a difference where and with whom you choose to do business.

Great dealership to work with.
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.

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 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.

I bought a 2022 Escalade ESV in 10/2023.
I bought a 2022 Escalade ESV in 10/2023. From start to finish there was no hassle I saw the vehicle and did not purchase for over 2 months shopping around for a better deal. I went to many Cadillac Dealers across Long Island and they did not take me seriously. When I told them what I wanted my payments to be they didn't even attempt to really search for a vehicle that could match my interests. This Dealership allowed me to test drive without prejudice and also were totally patient until I was finally able to clear title problems with my Credit Unions because of NY State Laws and then Finance with Cadillac. I was shown the vehicle features several times to at least get the vehicle off the lot. My payment was 1265.00.. but now I'm down to 1065.00 per month. I would recommend this Delearship to anyone in the world. They go above and beyond in Customer Service.
