Miss information on servive
Very upset that when I bought my truck was never told I had to bye a oil treatment after 15000 miles witch cost me 89. Dollars on my next oil change to keep my oil changes for life I was not told that when I bought my truck I think that’s crap not happy about that and don’t intend on paying for the oil treatment.
Updated model
Read many reviews and researched this vehicle and that helped me decide on this vehicle. Traded in a older suburban for this updated Yukon. Look forward to driving it.

2021 Yukon XL Denali Diesel 3.0
This Yukon XL has exceeded our expectations. We upgraded from a 2014 XL and it's like apples and oranges. From a size standpoint, the new design allows my 6'6 son to sit in the 3rd row. Not possible on the 2014 xl. Also, they have upgraded all of the finishes and with the new 10 speed tranny the XL drives and feels amazing. We also opted for the 3.0 diesel as that's what was available. We didn't even test drive one as they are hard to find - but man are we happy with the engine, gas mileage, and just how quiet it is. In city driving we're getting about 22 mpg, and then on highway expect to get about 27. Safety features and heads up display all work great. And, the sunroof thing is amazingly huge. Well done GMC and I highly recommend the Yukon XL to anyone that needs to move people in comfort. :)

Recently purchased a new 2025 Z06 from here. From the moment I first inquired about the vehicle until I took delivery, I experienced great customer service. Brian Olson is the dedicated Corvette specialist there, and he was great and very easy to work with. Highly recommended.

The team at Trent Cadillac is top notch, and will go out
The team at Trent Cadillac is top notch, and will go out of their way to make sure you’re taken care of. They treat you like family there, as soon as Gina met me for the first time after talking to me on the phone she ran up and gave me the best welcoming hug! Huge shout out to Mike Pecha for going above and beyond in every step of buying and taking ownership of my new Escalade, from staying late because of flight delays, to calling a nearby hotel and getting the best rate possible on a room. I literally have nothing negative to say, it was 2200 miles away to purchase a vehicle from them and I would definitely not blink an eye at doing it again because of the team there. Thank you again Trent Cadillac for the stellar service

On a summer trip and needed the first oil change and tire
On a summer trip and needed the first oil change and tire rotation. I am a handicapped driver and had a problem with an adaptive part of my van. After the service was completed, in record time, I asked, could someone in service check my problem out. Although not part of their Honda mechanicals The service manager and another fine gentleman took a look at my problem, diagnosed it in short order and reconnected a loose electrical connection. Then they secured the wiring out of the way to prevent it from being disconnected again. They refused to charge me for anything. I cannot speak highly enough about how pleasant and efficilent everyone was. If you have a Honda and are near Dover Honda in New Hampshire, that’s where you should go for service. If I were looking for a car I would go to them first and last. They deserve an excellent rating from my experience. The Best ! Charlie

Josh Ballard
i recently bought a car from her but my tires were flat and i came to get help. hours spent at the dealership can be awful but out of all the hours i’ve spend there this past month getting my new car this was my best experience yet. Josh Ballard helped me out with getting new tires he was timely on everything and made sure to get the best answers before contacting me. he was so attentive in every detail. this is my first time dealing w a car alone since i’m in az for college. he was unable to get the car delivered to my school and he knew i need to ask for a ride to get to the dealer before i could even respond he had already sent me a lyft pass so i can ride to the dealer! he made sure i didn’t make any unnecessary expenses and he made sure i had my car back to me asap!
