Milford Auto Group
This is simply the finest dealership anywhere. First of all it is family owned and every member of the family actually works there. One of the owners, Bob Fedor, personally oversaw the purchase of our new Ram. He was 100% available and was in the background throughout our entire experience making sure everything went perfectly. He is honest, caring, and completely forthright. By the time we picked up our new Ram we felt like we were a part of his family. Our salesman, Mark Setaro, couldn't have been more professional or helpful. Mark was knowledgeable about every aspect of our purchase and helped me from start to finish making himself available at all times even when he wasn't working. Buying a new vehicle can be extremely stressful, however, when you have a professional such as Mark guiding you through the process it is anything but. The purchase of our 2022 Ram Rebel was a surprise gift for my wife and Mark and Bob went to great lengths to make it all happen. I can not express how appreciative I am to them both or what a great experience this has been.

This truck is the base model and that is exactly what we were looking for. A good solid truck without all the fancy technology. It drives like a dream, handles just as well and the interior is sleek and well designed. Perfect black on black exterior.... a man's truck.

Service is always tops Sales department the best Would recommend to anyone looking for a new, used car or service. Blasius Chevrolet is, by far, the best dealership in Connecticut
Like the truck but also disappointed
Got the duramax diesel and getting 24 city and 32 highway is very good. Truck drives nice and is very comfortable. My 2 issues with this truck is the backup camera at night is useless (very dark) and interior lighting is not very good. You would have thought a 78k truck would have footwell lights, but it doesn’t.

I thought I should have gotten a better price on the car but who doesn’t? Kahled was my salesman and I couldn’t have had a better person. He is a very caring person and does his best to make everything in the deal go right, for the business and the customer.
Yukon Denali all new styling and pleasure to drive
Nice styling,interior has a new design dash which is beautiful and convenient,safety features and cameras are great and easy to used and the active cruise is awesome.

On Saturday, June 7, my daughter and I had an outstanding
On Saturday, June 7, my daughter and I had an outstanding experience at XXX Chevrolet. While my initial intent was simply to support her in purchasing her first vehicle, I ended up trading in my own car and driving away in a brand-new 2026 Equinox — while she purchased a 2025 Colorado. Both vehicles impressed us during the test drive. The safety features, interior design, storage space, and overall aesthetics sealed the deal for both of us. While comfort and safety were top priorities, what truly set this experience apart was the exceptional service we received. Steven connected us with Brian, an outstanding sales specialist who was both highly knowledgeable and incredibly personable. He built immediate rapport, listened carefully to our needs, and guided us to the right vehicles without any pressure. The process was smooth and efficient — we were both driving off the lot the same day! The dealership itself was clean, welcoming, and even treated us to a delicious lunch during our visit — a thoughtful touch that made the day feel even more special. I’ve purchased several vehicles over the years, but nothing compares to the level of service we received from Steven and Brian. I highly recommend them to anyone looking for a car-buying experience that’s professional, honest, and genuinely enjoyable. Judi and Jackie T.

2019 Sierra SLT X31
I purchased a new 2019 SLT with the X1 package. It has the Red Quartz Tintcoat paint. I usually never leave reviews, but honestly this is the most comfortable, nicest loking truck I've owned , and I've ownwd alot of them. The only issues I've had was the brake software was flawed, took it to the dealer on recall and they installed a new software patch, Other then that I love the styling, performance and the interior is very nice. No regrets

For the farm, it has excellent towing capability and for the hour long drive to go see my girlfriend, depending on the weather for traveling, I can get up to 35 miles to the gallon!

My experience at Northwest Hills Chevrolet was
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)!

Beautiful Truck
I bought a 2019 GMC Sierra Elevation. I traded in a FULLY loaded 2015 Sierra SLT, that I was really sad to see go, but the Elevation really sold me on styling and ride quality. I lost a couple high end bells and whistles, but the overall performance and look of the truck make up for it big time!

If I could give more stars than 5, I definitely would!
If I could give more stars than 5, I definitely would! Lila Bubier, Mark Deal, trade checker and Kia Finance went above and beyond to get me out of my negative equity from my Hyundai Ioniq 5. I am so grateful to have a new 2025 Kia Sorento Plug-In Hybrid. I had originally went in February, but did not come away with a deal. Lila has consistently reached out to me asking if I was interested and provided many different options to get me at the price point that I wanted. It was not easy, but we made it to the end goal. My growing family and I are so grateful to have this amazing team working at Kia and I hope to continue this new relationship with them at Blasius for years to come! Thank you so much!!!!
Pleased that I made this purchase
Waiting for the Refreshed 2022 AT4 was well worth it! With all the manufacturing issues today, building and shipping was slow, but understandable. Love the truck and the features! Fit is perfect and quality is #1. Pricing was too high but all vehicles are running this way. You get what you pay for and this truck is perfect! I have owned many trucks and this by far is the best. The latest features are beyond most other makes and GM has thought this truck through from front to rear.

Review of Valenti Volkswagen Hartford and Ty Curry
I would like to commend Sales and Leasing Consultant Tylon ("Ty") Curry and Valenti Volkswagen of Hartford, CT. As a recent college graduate, I worked with Ty on the purchase of my first car: a certified used 2017 Volkswagen Alltrack. Now several months since purchase, I continue to be very happy with this car. Ty Curry and everyone at Valenti provided the highest level of service and attention. I would be happy to return to Ty for my future vehicle needs. He was personable and friendly, while being very professional. I especially appreciated his knowledge, attention to detail and responsiveness Thank you Ty for your efforts to make my experience fun and stress free!
"THE" GMC Truck!
I have a 2023 GMC Sierra 1500 Denali with the 3.0 Diesel engine. I have 20,000 miles on it at the time of writing this. Never owned a diesel before and now i don't think i will own another one without it. I LOVE the engine in this truck. Only complaint would be that it likes DEF fluid while towing so pick up some extra DEF before you head out to tow something. Put about 8K miles on it this summer without adding any DEF fluid. seems to use a little more in the winter or when towing. Very quiet for a deisel and the fuel economy is awesome. Driving 70 mph down the freeway this truck gets about 30mpg, Drive 55mph on regular highways and this truck gets almost 40mpg. All around driving for me is about 26mpg. I used to fill up twice a week with my gas motor and now only once a week. Wireless Apple Carplay works great and the voice texting and mapping is a big plus. I also have the new SuperCruise feature which is awesome. Get on the freeway and set the supercruise on and the truck drives itself until i get to my exit (about 28 miles from home to work). Bose stereo is out of this world and all the storage is great to. I have a swingout bed toolbox, aluminum roll up tonneau cover, Lighted black GMC front emblem, Gloss Black 22" wheels, All Black decals and my dual exhaust bezels are black as well. I rotate the tires and change the oil every 5,000 miles. Couldn't ask for a better truck. Might get the ultimate next time as that has the messaging seats which i kinda wish I had.
