Thanks for your opinion.  I realise that the urquattro is rare.  I basically
believe that it is a sin to have these cars and not use them for what they
where designed for eg going fast.  A stock 10V or even a 20V wont do that in
my opinion.  I want similar power to that of the group b rally cars, without
the unreliability and expense of a highly stressed 5 cyl engine.  The extra
capacity of the 2.7 should help here, also the more modern 5 valve head is
excellent for power.

At the end of the day its just a car.  I know it's a "special" car, but it's
a car.  It is the driving of something that I have built that gives me
pleasure.  That's why a new s4 wouldn't interest me in the same way.  Also I
couldn't fund it.

Thanks again for your feedback.
