New and used 2026 Cadillac CT5 for sale near Middlefield, CT

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

The CT 5 Sport is a hot ride. It’s loaded with all the bells and whistles, from Supercruise assist to the hottest styling of the dash, it’s truly phenomenal! The change between touring and sport is seemless, there are so much to say about this car and not enough room!

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.

I bought a used Mercedes Benz E350 from them and the buying process was smooth, professional and painless. Alex and Joe were great to work with and I'd recommend them hightly. Thx

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!

Vinny at Sullivan's Northwest Hills was great to work with and to buy a car from. It was truly a good experience. He was very knowledgeable and let you lead the conversation. I will buy my next vehicle from Vinny the next time I need one.

My experience at Northwest Hills Chevrolet was exceptional. I was treated with the utmost kindness and respect, and accommodations for my special needs were made willingly, and in some cases, without my even needing to ask. My salesman, Phil Musmacker, made everything incredibly easy for me throughout the entire process (honorable mention goes to Brendan Elrick, who followed up on my initial request for info on the Equinox EV, and connected me with Phil). In addition, I never found any reason to question the pricing on the purchase order; everything was straightforward and exactly as I had been told, which is incredible considering my previous experiences with dealerships, where I had to fight to keep extras from being added to my order. Truly remarkable! I've already recommended Northwest Hills Chevy to a couple of friends! Thank you for a most wonderful experience (and I also really love my car)!

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 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.

Very fast friendly response from internet manager letting me know they just took a deposit and the car I asked about was no longer available. Didn’t push anything else which is nice.
