The staff at Portland Auto are top notch, and have you best interest at heart. I went for an issue a month ago, but when the tech didn't see any sign of it he encouraged me to go home and come back when I faced real issues so they didn't have to charge me for nothing. I did eventually go back when I faced issues, and the staff went out of their way to find a resolution. When their work took longer than expected they were easy going about lending a loaner car, and that was very helpful. Can't recommend their services enough.
