2021 GLC300 4matic
I absolutely love this compact SUV! Coming from a Subaru Outback, this is light years above and beyond for same year. A quiet cabin is my top want for buying a car. This cabin is quiet and relaxing inside. I’m tall and there is plenty of room. The seats are incredible! Can’t wait to take it on the roads in winter.

We were in today looking at the Murano and Dwayne was an excellent salesman. He was very engaged, knowledgeable and accommodating. Probably the best service I have had car shopping ever.

AMAZING!
We loved our experience with Colonial Cadillac! Everyone was so helpful and answered all the questions we had (and there were many). Highly recommend!
Exceptional Comfort
I have had this vehicle for only one month so have not developed much experience with it. I did take it on a 1400 mile trip two days after purchase. It ran well, was very comfortable to drive, made for a very easy trip, was great on gas mileage, and it is very quiet inside the cabin. Seat comfort is exceptional and this, being our first experience with heated seats and steering wheel, was most enjoyable.

Friendly reception, mechanical inspection mediocre
Two weeks ago we found a Jeep Rubicon on their lot that we liked, low-mileage with lots of pricey off-roading upgrades that made the price seem reasonable. My husband was thrilled. We decided to make the two hour drive from Southern Vermont, and were greeted warmly on arrival. We had easy rapport with Ted, and excellent conversation during the long financial process with Zach (okay, if I’m honest it was only long because we couldn’t stop talking). Three days later we returned to pick up the Jeep, which needed an O2 sensor. A couple days later my husband noticed the Jeep didn’t have a muffler - someone had taken it out and their mechanic apparently missed it - the sound hadn’t changed from our first visit and test drive. Fortunately, a quick phone call sorted it all out. All in all we’re very satisfied with our experience despite being a little surprised such an obvious piece, needed for inspections throughout New England, would be missing from the vehicle. However, their assurance that they must sell an inspection-ready vehicle, and quick action to right the issue saved their review, and our overall impression. Thanks, guys! We can’t wait to get out on the class 4s!

Dakota was honestly the best sales associate I have ever
Dakota was honestly the best sales associate I have ever dealt with. She was professional, kind, straight to the point and fast. I was able to close my loan in 3 hours even with adjustments needing to be made on the paperwork because she made me a priority. Dakota was responsive to all of my silly questions and made sure my car was ready when I was available to pick it up. I would 100% recommend Dakota to anyone looking for a new or used vehicle because she will make it happen fast and smooth
