Should I buy this 86 5kCS Q T?

["Robert J. Albrecht" <albrecrj@alfredtech.edu>]

I have found an '86 5000CS Quattro Turbo with 58k miles apparently in
very nice shape, at least to my inexperienced eye. The shop has let me
drive the car over the weekend. They are asking 4675. I find average
book at 3700. Am I way off? 

Here's what I have found so far. Can you advise as to the seriousness of
these items and what specific questions I should ask of the shop before
we deal?

1. Rack and pinion mechanism has a leak, says my local nonAudi grease
monkey. Steering was sloppy when I first drove it before the shop beagn
to work on it. Now it is tighter but there is creaking in steering
column. Might be just plastic housing, or is it more serious? What
should I ask for?

2. Leak at power steering pump.  What should I ask for? Related to r&p
problem?

3. It has the electronic push button climate control and I'm not
gertting a lot of heat. Core problem? Valve problem? Electronics
problem? How do I know?

4. On a cold start, there is a clicking sound when it begins to run. My
4000Q doesn't make that sound with 170k miles, i don't think. Should I
worry about that sound? It goes away after running a bit. What question
do I ask the shop owner?

5. No heat in seats. Fuse is ok. Is this typical? How do I know if there
is a broken wire? How expensive a fix? Any alternatives?

6. An intermittant failure of dash lights. They always light when I
start the car but sometimes when I turn on the driving lights, the dash
lights fail. Every third time or so.

And that's it. Body and interior is gorgeous. There have been two
owners, one from 1986 to Dec 1997, and one from then until now. Car was
first registered in Ithaca, NY. It's a pearlescent white -- any problems
with that?

What have I not looked for? Oh, one more thing. In some American cars,
turbos die young. What's the story with this Audi version?

Thank you very much for any advice.
Bob
