Hassle free on buying cars on them but service is not so good. Bought my Honda odyssey here but got cosmetic issues like popping sound on the sliding door and deep scratch on floor panel. Service advisor is accommodating but trouble on ordering parts. We live at Napa so we have to drive a couple of times to have it check, have an appointment and unfortunately now have to go back again to install the right floor panel. We had our van car washed for the first time then I'm seeing faded paint on the back side of it. Honda Corporation, I need your attention on this.
