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.
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.

Nothing but positive, seamless and professional.
Nothing but positive, seamless and professional. This dealership was not my first stop but it will be the only one I buy any future vehicles from.
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.

Excellent buying experience!
My family drove two hours from RI to buy our new GMC truck at Ingersoll. The price was excellent and the service was outstanding. Kyle, the GM of the dealership greets you when you arrive and even puts the temporary plate on your vehicle. Truly an outstanding experience. 👌🏼
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.

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.
One very awesome vehicle.

Highly Recommended Dealership
I have been dealing with Bolles Motors since 1987. I purchased 3 Jeeps from them -- a Laredo, Grand Cherokee, Patriot -- and I have leased my last 3, all Grand Cherokee Limited. They are a great dealership and their service is equally outstanding. Brian makes it a point to say hello and check in with me every time I visit the dealership. I have dealt with Barry Pinto several times (sales/leases) and Dan in service is top notch. I wouldn't deal with any other Jeep dealership.
2019 GMC 2500 Denali Excellent Condition
Wonderful truck. Has had zero problems. I am trading for a new one. Truck is all original with no modifications. Truck is in excellent condition.

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

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!

Love this place!!!!
Really enjoyed this car buying experience. When the car started acting up they were all over it and fo t it to a Ford dealership for diagnostics. Literally refused to let them send the car back until they were satisfied that my car is tip top. Can't say enough about Dave in sales, Phil their awesome mechanic who advocated for me like it was his own car. Then the GM met with me to talk about the experience and stand behind the car if the same problem recurs. Jessica at the desk made a rough week much nicer. So pleased to work with Blasius of Middletown and will be a repeat customer for sure!!

Recently bought a used Lincoln from Blasius. Great experience! Ken McKay is a great guy. Took car of everything. Great car, great price, great experience. Wouldn't hesitate to go back. And thanks to Chris in finance as well. Another great job.
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.

Very easy to work with
Edwin was great to work with from the beginning. He reached out shortly after I inquired about the car and scheduled a time the next day to take a test drive. They were able to complete the purchase that day so I could take the car home. Overall, both Edwin and their Finance department were easy to work with.

After purchasing my Jeep Compass I noticed one issue that needed to be fixed. I brought vehicle in the next day & it was taken care of. Thank you Edwin for all your help. I I am very happy with my purchase.

Most painless car buying experience i have ever had. My salesman, Dave, greeted me even before the dealership was officially open. He had a laid back attitude and didn't come off overbearing or high pressure. From beginning to end the process took less then 2 hrs including one of the best detail jobs I have seen. Will recommend to anyone looking for a preowned vehicle.
