Loehmann-Blasius Chevrolet review
I got a good deal on the car.
I got a good deal on the car. Tyler was great to work with. If there was one thing to complain about, it was the time it took to work things out. I was there for four hours, just wish we could’ve cut down on the time.
2022 GMC Sierra 2500 Denali review
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.

Sullivan Honda review
I always appreciate the quality of Sullivan Honda's
I always appreciate the quality of Sullivan Honda's customer service and my experience even in the waiting room, complete with complimentary coffee and comfortable seats. I appreciate the attention to detail in the servicing of my vehicle as I need to keep it in tip top shape for year around driving to and from eastern Connecticut.

Blasius Pre-Owned Auto review
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

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.

It was a good experience.
It was a good experience. The lead sales man was a little on the rough side. But all was good.

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.
