Used GMC Sierra 2500 trucks for sale near Port Jefferson, NY

i bought a jeep from here and i was unsure of the vehicle i wanted at first but after i was there i was able to test drive a few different cars and figured i loved the jeep i bought i had a budget that i couldn't pass and the car was more than that budget but after i sat with Pablo we were able to get it under my budget beyond grateful for them as i am still driving the car to this day with no problems but i recently went back and bought a car for my son i all went very smooth and i don't have any complaints i would totally recommend them and i will be going back for my next vehicle happily

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.

We recently purchased a Cadillac and worked with Victor during the process. He made the entire experience seamless and stress-free! Victor was professional, knowledgeable, and incredibly efficient. He had everything ready for us, and we were in and out faster than we expected. It's clear he values his customers time and ensures they get exactly what they need. Highly recommend working with Victor if you're in the market for a new vehicle.

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 staff, good prices, Greg (salesmen) was amazing, and Jim got me best rate possible even though he didnt have to he kept trying and got me a nice low rate. Now I hope and pray my 2014 Nissan Murano can last me as long as my Toyota highlander did (14 years) before it was totaled while parked. Will look to do business in future with Daddaro Dealer

Love my GMC. Owned a Chevy and this absolutely beats it hands down. Never had any issues. Inside is very comfortable and can't imagine driving anything else

if you go to this place ask for Oz... an absolute gentleman, and great salesrep ... very rare you find a man like that in the industry... overall 10/10 experience... never even asked me to write a review but my experience was too smooth not too

I bought a 2022 F250 from Blasius South, Victor C was great to deal with, the whole interaction was flawless, id definately come back again, very happy with my truck

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 all around, gave me a a fair trade in valve, would highly recommend.

One very awesome vehicle. Checks all the boxes you need in a truck and exceeds expectations on quality, performance, and looks great ,too. Love my nre truck.

Sean my service provider was excellent and insured my interaction with the service department went smoothly.

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.

Very fast friendly response from internet manager letting me know they just took a deposit and the car I asked about was no longer available. Didn’t push anything else which is nice.

What a gorgeous truck, runs good, sounds good and has all of the amenities I need although I am looking forward to their next interior upgrade.

They made sure the car that we wanted was road ready and safe for my family. Even after purchase they still are wonderful to interact with. I highly recommend them especially George, he goes above and beyond. We will definitely be return customers 😀

I've owned my truck for nine years now it is never once let me down. I'm about to put my first set a tires on it and brakes other than that I don't plan on getting rid of it it's never let me down and after reading all the other reviews it makes me realize they don't make them like they used to as they used too!

Recently bought a used Lincoln from Blasius. Great experience! Ken McKay is a great guy. Took car of everything. Great car, great price, great experience. Wouldn't hesitate to go back. And thanks to Chris in finance as well. Another great job.

This is the first diesel I have owned. The power is amazing and I really like the room inside the cab. This truck is a beast... Love it!

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.

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!

Quick and easy beginning to end. I saw vehicle online the price was good and drove it off same day. highly recommend this dealership. thanks colley

The salesman was great. No pressure and willing to negotiate. The finance guy was even better. Overall great experience buying a car.

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.

Go see Luis at Blasius South. He was attentive and very easy to work with. The whole process was perfect start to finish. Everyone there was helpful and very knowledgeable!!

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 mine in 2017, 2nd owner. It had 36,000 miles on it when I bought it, getting ready to turn a 100,000 miles, and the only thing I've had to do to it, is replace the Def heater, other than that, it's been a great truck. 👍

Just bought a Colorado from Blasius Branford and impressed by the quality of vehicle, price and service. Joey Posa and Mike De’Angelo were great to work with—highly recommend

Mike and Chris were awesome. Chris in finance was extremely helpful. Would definitely recommend. Great service department also.
