Visiting from the east coast with a Prius 2010. Had to replace the inner fender liner on the front left side. Same work was performed on the right front inner fender in Kansas 2 months ago at a total cost (before taxes) of $140 (part and labor). Toyota of Portland did the same work on the left front and charged $253. How can it be that same service (part and labor) costs $113 more (80% more) at Toyota of Portland???. This info will be sent to TOYOTA USA headquarters. Would not come back to this service shop!!!
