MacPhereson struts?  What are they good for?  Well, I don't understand all
of the geometry involved, but here are some guesses:

	1)	They are lighter than the double-A-arm.  When you are trying
to cut total weight down, you have to avoid doing too much violence to the
sprung/unsprung weight ratio.

	2)	It looks to me (like what do I know....) that they free up
a little room under the hood.  You can put something where the upper A-arm's
pivot would have to go.

	3)	When you are designing for lightness and bringing in computers
for finite element analysis, the double-A-arm might (and then again might not)
result in a much simpler set of equestions to get ground down.  How would you
like to have the length of your compiles tripled?

Does anyone know better than I?
