89-91 100vs200t

[Matt Jackson <MJackson@connectsoft.net>]

I am in the market for an 89 - 91 100 or 200. I am curious what problems 
these cars tend to have and other things to look out for when buying used 
audis.  I have been surprised to find same year 200t's priced similarily 
to the 100's.  I assume that is because buyers are leary of the turbo on 
the 200.  Any information would be a great help.  When I traded my 1980 
5000s with 200,000 miles in on a V8 Mustang Conv. a few years ago I had 
no idea I'd be back to Audi in such a short time.

Thanks, Matt
