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!

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.

Amazing experience with both the salesman (Vic) and finance department. Vic was amazing. Courteous, helpful, absolutely no pressure or “up-sales”. Entire process took less than three hours. Highly recommend. Seamless experience. Thanks again Vic.

Good vibes
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. Service prices appear to be fair. Will definitely continue with my service here, also would consider a purchase from them in the future.
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.

Second time around was just as good as the first. It felt like visiting friends, not a transaction. I wouldn't hesitate to recommend Hamden for either a purchase or service. I'll drive further to get to this location since I know the time will be well spent.
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.

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.

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

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!

Highly recommend Sound cloud auto in Branford CT.From my first , second and now third car , visit to driving off the lot, the process was smooth and efficient — they got me into a car quickly and the whole process was as easy as 1-2-3. Special thanks to Dave; he was friendly, patient, and made the paperwork painless. If you want a fast, no-nonsense car-buying experience at sound cloud auto are the place to go. I will definitely recommend them.

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!

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.
