Audi buying advice

[Robin Gates <72355.650@compuserve.com>]

I am very seriously considering purchasing an Audi 90 Quattro or a new A4.  However, 
I have been having a hard time getting good information on them.  I am very 
interested in any reader feedback on reliability, general satisfaction, performance 
add-ons.  I think I can get a good deal on a 95 Audi 90 but was hoping that the new 
A4 might have a little more room in the back seat?  Any thoughts on whether I should 
buy now or wait?  Thanks.
