True, but I would state item 2 as "They do not *allow* adjustment for castor
or camber". This, plus the fact that they give generally poor wheel geometry
are both deficits.

The 1980 Mustang I bought new with struts is the only car I have ever
owned for 65000 miles with no work done to the front end.  No
bad tire wear, no pulling to the left or right, no new shocks and
no alignments.  Also, very good handling.  I have a 69 and 81 Camaro
and wish that I could make the same statements for either of them.

Not true!  My car has McPhersons and its wheels are round.:-)

My Daytona also allows adjustment of camber by bolts which hold the strut
on which is why replacement of the strut requires a re-alignment.  So far
I haven't gotten any responses on this that seem to indicate any advantages
to the things.  I had thought that Macphersons originated from the race
track circuit and that there was some concrete reason that they were better
not just cheaper (for them).  Sigh.

I have Macphersons on an 81' Skylark and after 79k miles, including
about 15k of towing a sailboat, they're still O.K.

True, but realize that degradation in struts is often of the gradual
loss of performance kind and the affect on handling is not necessarily
realised until you buy new ones and feel what a difference they make.
I bought a sporty car because I wanted it to handle well ('84 Daytona Turbo)
and I'm not going to be willing to put up with much significant degradation,
I would rather replace the strut.  Most guides I have seen rate them to
be good for ~40,000 m.  I'm certainly not going to wait for catastrophic
failure modes.
