Our Reviews
Out of all the car purchases I’ve ever made, working with David & Chris at Blasius GMC today was the best experience of all of them! Chris in finance was super patient, honest and straightforward with us. David was really knowledgeable about the car I purchased & helped get me set up and comfortable in it as a first time owner. I would highly recommend anyone in the market for a new vehicle to check them out!
Stephen (Wtby),Mike and Nick (Branford) were very accommodating. Mike explained to me all of the options and walked me through everything. I would definitely recommend Blasius for your car needs. Thanks guys!! Can't wait to pick up my new Infiniti
Great experience, process was seamless, Ken McKay is the GOAT of car sales told him my magic number and he came in under it!!!
Made a reservation online. My truck was repaired without issue. Josh the service rep kept me informed on the progress.
The experience was great, I purchased a 2025 Sierra Denali I was well pleased with Ken and the rest of the staff Thank you for the experience .
Gene was one of the best salesman I’ve ever worked with. Never made me feel pressured to buy nor tried upselling me unnecessary ad ons. Great group of workers here.
Great group of employees. Very helpful and knowledgeable which made the process easy. Much thanks
Mike, Joey , & Gene all contributed to make the sale possible. As straightforward as it gets, answered all my questions and requests promptly.
Everything was great as I expected.
Team approach ensured that communication was quick and thorough. Personal connection and attention to details in conversations made the process a pleasure. Fair pricing and no hassle sale. Will recommend.
Awesome professional staff to deal with.
"I recently purchased a new car from Blasius GMC Branford and had an amazing experience thanks to Michael D'Angelo. He was incredibly helpful, knowledgeable, and patient throughout the entire process. He listened to my needs and worked tirelessly to find the perfect car for me at a price I could afford, providing me with the easiest, pressure free buying experience. I highly recommend Michael and Blasius GMC Branford to anyone looking for a new car!"
Mason and Joey hooked it up!! Quicker than a haircut and I left with a Denali. Very good service. Thank you guys !
Ken McKay is a true and trusted professional that I have known for close to 20 years. I have purchased several vehicles from him throughout the years as it’s always an easy and enjoyable process. I would recommend Ken, who is also a great person to anyone looking for a new or used car.
Michael D’Angelo and Joey at Blasius GMC provided exceptional assistance in helping me purchase my car. I am sincerely grateful for their help.
We worked with Mike on getting a car and he was so helpful, so comprehensive and talked us through every step of the way. We are so happy with the car and the kindness we received.
Quick and easy. Ken was great as well as Joe. Would highly recommend
So far so good! I went to test drive a car. It wasn't for me, but I really appreciated the experience: unlike most dealerships, there wasn't a lot of pressure put on me; the sales associate, Mason, was fantastic, and he promised to update me when they found a car that met the criteria I was looking for. That was a week ago and I haven't been inundated with calls/emails/etc. I did receive one text clarifying what I was looking for. This has been a really pleasant surprise, as I've had pretty bad/pushy dealership experiences in the past.
Great service, and a great overall experience. Thanks Ken & Jack.
Thank you so much Mr Ken and Mr Chris for all your help today, for making this process smooth as possible and stress free.I love my new ride
Great and fast
The guys at Blasius GMC hooked me up with a great deal on my Jeep Rubicon ecodiesel. This was a long distance purchase, they had my Jeep shipped out to me and I couldn't ce happier!
My husband and I had an amazing experience purchasing a vehicle with Mike and Joey. The team was professional and courteous through the entire process and answered questions with respect and grace.
Gene was excellent and very easy to deal with. Everything was done just as promised and on time. Chris in finance was also a pleasure to deal with, had me in and out of his office in 15 mins. Best vehicle buying experience I’ve ever had, zero complaints
Great experience a well run store. Everyone was very polite.
