Missing updates -- now what?

["Scott McMullan" <mcmullan@xxxx>]

I spent a bit of time on my car this weekend, and crossed off a half dozen
things from my list (Yipee!) but discovered my car doesn't have some of the
recommended updates including: throttle cable shield (already knew that
one), front-end suspension, and ball-joint nut. At least the fan-fail
update was done!

So, I am stuck with some questions, like is my car safe without these
updates (or should I stop driving it to work?), who sells the parts to do
the updates, and should I try to get my "normal" mechanic to do this, or
should I really seek out PJ Grady? Everyone says Grady is great, but
apparently it can take a long time to get your car back -- definitely not my
favorite idea given how much I enjoy this car!

As always, thanks in advance for your suggestions.
