90 20V newbie

["Hardwick, Robert C" <Robert.Hardwick@PSS.Boeing.com>]

I purchased a 1990 90Q 20V on Saturday and have a few questions:

1) Service manuals:  appears to be two varieties, one by Bentley and one
by Audi.  True?  If so, which is superior?

2) Brakes/wheels:  Mine has 195 x 14 on BBS.  Magazine tests cars had
205 x 15 on Speedline.  Was this a specified option?  Does wheel size
designate one brake size/type?  Are the recent queries regarding brake
improvement specific to the smaller brakes?

3) Clutch engagement:  The clutch engages through a very short stroke
length of the pedal, near the top of the pedal's stroke.  Aside from
getting used to it, which with the peaky engine makes for non-chauffeur
smooth starts, should I be concerned, i.e. is this normal?  There is no
evidence of slippage or stuttering from flywheel burns, mostly just new
car paranoia!

I should also add that if it wasn't for this list, I wouldn't have
learned to seek this wonderful car or have found the example which I
purchased.  Steve Watson, a friend of the seller, Joe Thompson,
contacted me due to a "car wanted" advertisement which I placed in the
Quattro classified webpage.  Steve also looked over the car for me.  The
car was in Chattanooga, me in Seattle.  I flew out over the weekend.  It
was all that I'd been told, and with mileage and a price never seen in
the NW!  If anybody sees a Tornado Red 20V on a carrier truck headed
west....

Thanks Steve, Joe, and all on the list.
