Porsche 911's, Maserati Ghibli's and Quatroporte's use dry sump.

I suspect that these may be some of the reasons more cars don't
use dry sump oiling systems:

* Costs more to manufacture -- extra oil pump to scavenge oil,
   oil tank, plumbing.

* Reliability -- more things to fail -- pump, lines. =


* Would further confuse typical driver and gas station attendants,
  who wouldn't know how to check oil (usually with engine running).

* Increases oil fill requirement -- would make oil changes more
  expensive.  My 911 uses 10.6 qts to refill.
