I've noticed some scary price trends on little-used parts at some of of the internet dealers.
A headlight wiper is $287, a clutch/bearing for a smog pump is $750.

I guess as the cars get older, we are faced with more salvage parts, or a little less relentlessnes in keeping them perfect.

I have a few boxes of original Bosch H9DC plugs; maybe I'll hoard them for my later retirement income.
