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.

We would like to give a huge shout out to Aden
We would like to give a huge shout out to Aden Stroble, Aden is doing a great job and hoping that he continues his career at green chevrolet he will go far. My husband and I actually left the car lot after driving a couple trucks, as we drove down the road and thought about all the knowledge we were told about the Silverado that we drove . we turned around and went back and we bought the truck! Job well done Aden also a big shout out to Ashley Jones and Terry in financing , thanks to a good group at green chevrolet, we will be back George and Michelle Gonzalez
Very comfortable to drive and relax in!
This truck was exactly what I was looking for! Great ride, and it will haul every thing that I need it to.! Low mileage without new car up front expense!

Worked with Tyson on texting. Found just what I was looking for. Went to dealership to look at it and as soon as I walked in he welcomed me using my name. They were very helpful and very knowledgeable. I couldn’t ask for a better experience.

Best Car Shopping Experience Ever!
The Integrity Auto Center team is fantastic. Knowledgeable about every vehicle on their lot, fair, honest, and straightforward. I spent an entire weekend car shopping all over KC, and this was the only good experience I had the entire trip. We live four hours away, but I would drive back to do business with Integrity anytime I'm looking for something new. A Overall
In about 15 vehicle I had, this the best one
This truck just need nothing, comfort, strong, and beautiful, it's great for work, and for personal use, my next car will be the same but new

Easiest Car Purchase Ever
These folks made this so easy to buy a new truck. They offered a fair trade, a competitive package, and had good customer service throughout. I appreciate their willingness to work hard for the sale. We had arrangements wrapped up before other dealers had even responded to my request for information.

Everyone at Walser Nissan in Wayzata made me feel welcome
Everyone at Walser Nissan in Wayzata made me feel welcome and comfortable. The show room was clean and comfortable. I was met by James Lackay who proved to be knowledgeable and attentive to what I had to say and he was very personable. He was persistent in finding the car that I wanted and so far, I'm very happy with it! I would highly recommend James to assist you in finding the perfect vehicle!

I was searching recently for a Honda Accord for my 20
I was searching recently for a Honda Accord for my 20 year old granddaughter. I started my search at cars.com. Within a few minutes I was able to get a sense of the price range for a good used Accord. I spotted a 2017 Honda Accord with 67,000 miles at Crafts Motors in Lisbon, Maine. Most of the other vehicles had over 100,000 miles. I called the dealership and spoke to Mike Storm. He gave me a brief history of the car. We were able to test drive the car later the same day. Three days later one of his drivers met me at an independent auto repair shop. They gave the car a clean bill of health. My granddaughter purchased the car later that same day at a very competitive price. I highly recommend doing business with Mike Storm and his team mates at Crafts Motors!
