Duncan's did an amazing job with an unusual problem on my aged Nissan Murano. I had a hesitation problem ( my car would not accelerate on inclines beyond 10 MPH for a full ten seconds, and intermittently when I was on flat surfaces). My engine light never came on, and it was really puzzling.
The team at Duncan's assessed my car, gave me feedback and pictures of what they found and even arranged for a loaner car. I haven't had a loaner car unless I was working with a dealership previously.
After Duncan's fix, my car is running better than I had imagined, and I felt informed about what was going on through the process. The bill made sense to me, and was broken down in a very sensible way.
I drive away feeling that I have received quality service at a reasonable price, with a car that will continue to perform.
