Why Why Why???

You guys are way more informed than me and I appreciate all the good stuff I learn here. I love my Boxster but can no longer wonder why Porsche makes some or the choices they do like -
  • use a sealed, greased, ball bearing on the IMS which is submerged in the sump. The use of a common casting for both cylinder heads required the IMS, but at what point did someone say, "Hey, how should we put a bearing on this end of the IMS?"
  • use a grade of plastic on internal headlight lenses that will turn dark with burn marks even if you only ever use stock halogen light bulbs.
  • use soft-touch black paint on interior trim panels that turns sticky with age.
  • design and specify a water pump that should be replaced at intervals to prevent engine damage from broken impeller bits migrating to cylinder heads and causing hotspots.

Signed, glad I don't own a GT2, GT 3 or Turbo requiring me to have my cooling system fitting welded to my engine block!
