Checking Out 5000CSTQ

[Charles Schwartz <cschwart@stern.nyu.edu>]

Hi Everybody,

I'm going to look at an '87 5000CSTQ on Sunday.  This is a one owner car
with 118K.  The owner didn't do his own work, but has receipts from a from
a non-dealership mechanic.  The car has the original steering rack and
accumulator.  He replaced the timing belt, water pump, lifters and brakes
(whatever that means) at  about 100K.  

My questions are:

What's the quickest way to check the steering, suspension, and brake systems?

How do I check out the turbo?  I remember reading that the boost should be
1.7 bar in 3rd gear.  Is that right?  How do I test the boost exactly?  How
do I know if there are any leaks?

Should I do a compression test on the cylinders?  If so, what should the
readings be on a warm engine?  What exactly should I disconnect if I do?

What else should I look for besides the obvious such as windows, locks, ac,
and the things I can readily see? 

Mostly I am worried about the turbo and its various components.

Thanks,

Charlie
