Jose seems like a good salesman still looking for a
Jose seems like a good salesman still looking for a Ridgeline in my price range. I am not in a rush . Something will come along. If there's any recalls for the Ridgeline I believe the dealership should take care of before purchase. If there's a issue. The 2017 Ridgelines had transmission problem 6 speed. I have to do my homework when making a purchase. Don't have 12,000 to replace a transmission plus a car payment.

Honda Marysville Dealership is simply the best!
Honda Marysville Dealership is simply the best! If you’re looking for a new vehicle this is the place. My sales person Matt W. Was excellent, I worked out a deal at home via phone, email or text, which reduced my time at the dealership. Which resulted in a great buying experience. I was surprised at the number of customers and friendly sales staff on a Monday well that speaks for itself. So if you are looking for a new or used vehicle Honda Marysville was worth the drive.

My GMC Sierra is the best ride I have had in all the years that I have been driving. I started driving in 1977. I love my new Sierra.
