Great dealer.
Great dealer. No hassle. In my new vehicle the same day. Smooth transaction. Very happy with whole experience.
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.

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.

Ask for Demario, he is the best!
Ask for Demario, he is the best! He is amazing and makes the car buying process really smooth. He goes above and beyond for his customers and explains every step of the process to you. Demario exemplifies excellent customer service and attention-to-detail. I highly recommend this dealership. He provided 5-star service at every step! It could not have been more seamless, and he made the process very pleasant. His attention to detail and my satisfaction was unparalleled- going above and beyond in every aspect! Thank you.
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 service every time
I bring my fleet vehicle here for repairs/maintenance. Other dealerships have treated me like a second class customer because the fleet company pays for everything. I have never once felt that way at Sullivan's. They are always kind and have gone above and beyond for me at times. My husband became a loyal customer here because of their great customer service.
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!

Service
I had an excellent experience with having my car repaired at Ingersoll Chevy. My car was diagnosed and repaired as promised. The whole service department was friendly and knowledgeable.
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 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!!!

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.
Best truck I've owned yet
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.

Had a great buying experience here at terryville chevy. My salesman Peter was great and very knowledgeable. I highly recommend going here!
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 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!

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!
Beautiful truck

Was contacted by Zach from Waterbury dealership. Right off the bat I felt like he understood my needs and wanted to work a fair deal for the sale of my truck. We got it done and myself into new Colorado. Staff was very helpful and patient. I would recommend this dealership team to anyone. Thanks!!

I had a really great experience working with Michael Rose
I had a really great experience working with Michael Rose when I bought my 2021 Mach-E. He was super communicative, answered all my calls, replied fast to texts, and even got back to me on his days off. At first I honestly just came in to test drive a Mach-E and wasn’t planning on buying anything, but Michael was very honest and trustworthy and ended up helping me find a Mach-E that fit exactly what I needed and stayed within my budget. He never pressured me at all. The paperwork process was really smooth and easy. What I liked most was how Michael treated me like a friend during the whole process. He’s really funny, easy to talk to, and it never felt awkward or salesy. He even came in on his day off just to get the deal done a day earlier than scheduled because of snow, which I really appreciated. Even after I bought the car, he kept checking in to see how everything was going. When my tire pressure was a little off because of the cold, he helped get it taken care of super fast and was very flexible. This isn’t one of those dealerships where you never hear from the salesperson again. It was a pleasure doing business here and I honestly don’t see myself using another salesman in New York. I recommend Michael to everyone.
