Amazing service team, tech kept vehicle clean and service
Amazing service team, tech kept vehicle clean and service Consultant kept me up to date on my needed services and repair, pricing is affordable and fair
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.

Victor was super nice and professional and patient.
Victor was super nice and professional and patient. Knew much about the vehicle and its history and had maintenance documents ready to give me along with carfax. He also have the vehicle washed before my visit. He was very prepared. I did not buy on that day but I’m hoping to return should they agree to be flexible on their pricing. Seems like a well run dealership.
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!

A Beast when it comes to hauling!

Extremely nice staff, very professional team players from service desk to the shop. A very clean and safely run facility. Waiting area was comfortable. Service was done in a reasonable time.

Painless, fast, and rewarding experience ever!!!
I walked in with something very specific in mind. Even though I didn?t get the car I built online Colandrea was able to offer me the next best possible thing. I?m picky but their associate read my mind and was attentive to what I wanted. I looked at just one car and fell in love with it. Took it for a test drive and made the deal. The longest part of the process was trying to see which of the approval offers best fit me. They fought to stay within my budget. They found me the lowest payment option possible. I was in an out of there in less than 3 hours and returned the next day for my vehicle. Painless!!! This is my NEW dealership! Thanks to Floyd and Dan!

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.

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.
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.

I needed our transmission reprogrammed, I called the night prior, they had my vehicle in the next morning and returned by the end of the day. Everything I needed done was accomplished with no issues, they also kept me up to speed as they worked on the vehicle through an email link to check the status. Great job!!!
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!

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.

I had an outstanding experience purchasing my Cadillac
I had an outstanding experience purchasing my Cadillac Lyriq from Blasius Cadillac. Despite having researched the vehicle extensively through YouTube videos, sales representative Rich Noble took the time to thoroughly explain every detail during my test drive, ensuring I fully understood all the features. When I arrived late due to travel delays from Boston and a previous dealership appointment, the team was incredibly accommodating and flexible with my schedule. The pricing process was refreshingly transparent—we negotiated the complete out-the-door price entirely through email with no hidden fees or last-minute surprises. Most impressively, they coordinated with the Massachusetts RMV and delivered my vehicle directly to my home with plates and registration paperwork already completed, saving me an additional trip back to the dealership. Blasius Cadillac demonstrated professionalism, transparency, and genuine customer care throughout the entire process. Highly recommended!

Lou was my salesperson and he was super communicative, explaining and re-explaining when he seemed to feel it was needed. No surprises along the way, I was able to test drive the van as much or as long as I wanted, have a mechanic come by to inspect it and they washed it and added a full tank of gas on pickup day. They had done some quality servicing to the vehicle as well before pickup day. Lou mentioned early on that he wasn't paid on a commission basis, which was a good detail for me to know. In the end, all the numbers were the same from the beginning to end, no "uh oh" moments and it was a super fast experience on pickup day - probably the fastest ever for me to get the keys and drive a new (to me) vehicle home. I will look to use them again if possible in the next year or so. Highly recommend.
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.

Luis was a prepared, kind, and cordial associate who I had the pleasure of working with. After some honest negotiation and a little bit of elbow grease, he got me to my number. My Dodge Hornet has been great! He made buying this car a breeze and was very responsive over email as a pre-vetting process.

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.

Peter is a kind person and wonderful salesman. He is a credit to Ingersoll Auto Group! He helped make our lease go smoothly and efficiently. This is our second time we have worked with Peter to lease a new car, and he directs us to the perfect car for our needs.
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.
