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!
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 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

a place to go for bargains if you have patience
Alex excellent salesperson very patience and honest. The dealership is another story, if your looking for a reasonable price this is the dealership for you, they get cars from Auction so no idea about the history of the car, they get checked when you already signed for the As- is purchase, don't go there on a weekend, if you have patience, wants a bargain, (non negotiable deals)time, and good mechanic this is a place to go, got lucky with Alex very accommodating and great salesman

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!
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 deal.
Great deal. No gimmicks or nonsense. Thanks Sean for making it such a smooth transaction. When it?s time to for another purchase I will certainly be back.
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!!!
A Beast when it comes to hauling!
I love how the truck pulls and rides when towing. It will give any driver the confidence to tow anywhere. I haven't had a single issue with it. I love the way it looks and couldn't be happier.

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.
a great Truck
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!
