I always find these discussions interesting in that one buys the flagship Toyota vehicle of its time....
...and balks at a $20 piece.
And $17 is very reasonable for a Japan-manufactured part, with design consistency in the part.
We are of course seeing effects of the tsunami and supplier price increases from Japan, as well as the significant increase in the value of the yen (making parts expensive too) compared to the dollar.
That said, I've always advocated to customers to realize these aren't Corollas or domestic makes.
These are luxury SUVs. And while the trucks might be getting up in age, new OEM parts reflect flagship vehicle and new parts prices.
Good lucks gents.
