Jerry DeJesus demonstrated exceptional professionalism
Jerry DeJesus demonstrated exceptional professionalism and expertise throughout our experience. It was truly a pleasure collaborating with him. He took the time to address all of our concerns as parents of a new driver and successfully guided us in finding a car that was not only equipped with numerous safety features but also remarkably affordable. We extend our heartfelt thanks to Jerry and highly recommend him to anyone in search of a vehicle.

Found the specific, rare car for which i was searching.
Found the specific, rare car for which i was searching. It was at Blasius pre owned. I had never heard of them so I took the trip from NY to see the car. The car was as advertised and I bought the car. 3 days later I went back and took delivery. Every part of the transaction was great. From the moment I walked in I was treated respectfully and everyone there is so pleasant. There were no games/nonsense just a straight, easy deal. No upsells, no hidden fees, it could not have gone smoother. I buy lots of cars and highly recommend Blasius. Special thanks to Adam Betancourt the salesman and Bobby Fernandez the GM for making this such a great experience.
One very awesome vehicle.

Jerry is amazing!
Jerry is amazing! I really enjoyed finding my car online, and when I left a message about the one I was interested in, Jerry responded that same night. He even followed up with a text the next morning to let me know he’d check to make sure the car wasn’t already sold. Jerry—and everyone else at the dealership—treated us with genuine kindness and respect. I absolutely love my Rogue, and the color is beautiful! If you’re looking for a used car, I highly recommend coming here and asking for Jerry!

Great Service Department
In maintaining our 2020 Buick Enclave, we have used Buick GMC Watertown Ct, since our purchase in September 2019 and have always received the best on time, reliable service and friendly customer service on our visits. The staff that reviews what service I am requesting will always review for possible upcoming recommendations of service as well. The cost and approximate time of completion has always been spot on.
2020 GMC 2500 AT4
This truck is the truck that all others should look up to. It rides great, will tow a house, runs smooth, and gets great fuel economy. The Allison transmission is so smooth. The AT4 looks great too.

Great Truck
I paid over $106,000 for this truck with warranty. Do not care much about miles per gal. at that that price range. Just too much truck for me at my age.

Great purchase experience
John McCoy was a great salesman! He was honest, communicated well, and applied no pressure to make a decision. This dealership was the only one on Long Island that was willing to negotiate a deal on the car I purchased. Every other dealer said that they could not lower the price of the car even $1. This is the third vehicle that I purchased or leased from this dealership and I will return when I am ready for my next vehicle.
Beautiful truck
I love my 2021 GMC Denali 2500HD. I have gotten more complements on this truck than any other vehicle that I have owned. I get great highway fuel milage average 19-26mpg,which is great for a heavy duty truck!

Great Truck (sans MPG)
Love everything about this Duramax Denali except the fuel mileage. 13-14 Mpg tops when not towing. Bought truck cause previous was stolen. Wish I still had my 6.2 High Country!

Old lady in need of a vehicle!
Today, purchased the 2013 Nissan Juke, 112,600 mile for $9,995 today. It will be ready Wednesday or Thursday this coming week. My sales person Amy was excellent. She knew I had a firm budget (retired) and she found two great vehicles to test. The Jeep I could have taken home today with less milage... a little older, however, Jeep mph versus the Juke..., Nissan won even with higher mileage. So far, I'm "a HAPPY CAMPER"! I can't foresee any problems from now until pick-up. So, I'd say, if you need a reliable used car, Amy is knowledgeable and, in spite of the packed waiting room with eager customers, we were never abandoned. Note; yes, the sales people had to multi-task at times. Understand, at these reduced prices, compared to any dealerships for used cars... Patience, just a little patience - and you'll be treated right too. All the best to customers in need of a new used vehicle!
Best truck I have owned
I've owned every other American truck and this is my first GMC. I bought the 2500 HD Texas Edition. I absolutely love this truck. It's everything I could have hoped for and more. It is able to pull my 30' travel trailer with no problems. So now when we go out with our trailer I'll have no worries. The look and feel of the truck is outstanding. The 6.6L gas engine actually gets great gas mileage. It gets about the same as my Ford f150 ecoboost. Probably better on the highway. Looking at about 13 miles in the city and 15 plus on the highway. Definitely got a better truck for the price compared to any other american models with the same characteristic and options.

Excellent buying experience!
My family drove two hours from RI to buy our new GMC truck at Ingersoll. The price was excellent and the service was outstanding. Kyle, the GM of the dealership greets you when you arrive and even puts the temporary plate on your vehicle. Truly an outstanding experience. 👌🏼

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. "We Aim To Make The Journey Of Owning Your Dream Car Both Exciting And Accessible".
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.

Great experience
We went to D'addario's about a used Volkswagen SUV. I worked with Ed and he was phenomenal! Never made us feel pressured and the dealership worked with us on getting into the car at the price we wanted. Would highly recommend.
Most convenient options on any vehicle I've owned.
Great power and yet great economy. Love the safety features with the cameras and side vehicle warning. Camera that shows side of vehicle, including trailer when turn signal is on is great. Also appreciate the bed camera for hooking up gooseneck trailer.

I bought a 2018 Nissan pro x a little over a year ago.
I bought a 2018 Nissan pro x a little over a year ago. I drove from ny to look at it it was clean except for front bumper was hit in corner and paint was scraped. They repaired the damage perfectly by the time I picked it up. I was impressed by their professionalism. The only thing that I thought was a little extravagant was the dealer fee. We negotiated a fair price and now it’s mine. I’ve had the vehicle for over a year and it is flawless. I felt I needed time to make a fair judgement of the vehicle before my review. I would not hesitate to buy another vehicle from thi dealership
