Should I buy an A4???

[Elizabeth Monacelli <violin@sprintmail.com>]

Hello!
First of all, I don't know whether or not y'all remember me??  I am the
girl with the 1989 Audi 90, that had the odometer rolled back. This
happened back in Sept. '96.  I just wanted to inform all of you, that I
won the hearing!  The dealers comission was in my favor, so I get to
return the car, and get ALL of my money back, plus all the repair work. 
  Anyway, within that time frame, I bought a Toyota Corolla ('96).  Now,
my Mom's lease is up, and she wants to buy my car.  My question to all
of you, is should I buy a NEW A4??  I have looked at other models of
cars, like the Camry , Taurus, etc....   Does anyone one an A4 here? 
Could you please give me your feedback?  
How is the gas milage?
Is it true that it would be substanially more expexsive to repair?  
Does it last for a long time? 
What are certain problems all of you have noticed so far?
Would it be easy to put another stereo unit in the car?

Thanks!
