Audi 90 Sport

[Ernest Cline <clinee@nnr.dowjones.com>]

Can anyone give me some info (anything at all would be helpful) on the
Audi 90 Sport Quattro?  Did they even make one, I haven't checked the
blue book or edmunds, but I saw the car and it didn't say 'Sport' real
big on the back, that would tip off a dealer that it was one.  Its at a
Mazda dealer, so its not like they sell Audi's so that they'd know. 
Maybe the guy trading it in told 'em it was, and they believed it. 
Anyway, its a nice car, white with black leather, 5 speed, appears to be
pretty much loaded.  There is a little picture of a drivetrain and an
'off' button.  Um, you can turn off the AWD?  Isn't it really 4 wheel
drive at that point?  Or is it some sort of traction control?  Please
RTP and thanks in advance! (I'm going to go test drive it tonight,
hopefully, but I always like to go into dealerships prepared.  And its
raining, so, so much the better!)
