Sport Quattros

["Jouko Haapanen" <joukoh@vtoy.fi>]

Anybody out there have ideas of present day values of Sport Quattros?  I
know roughly what the asking prices are, but what prices do they trade
owners at?  I'm thinking of adding one to our newly opened Audi showroom
(not to mention my personal collection) and I have a few possibilities.

There are apparently a few_brand_new_Sport Quattros at Ingolstadt although
their condition may be suspect due to their extended layover.  These cars,
as they were never registered, may be next to impossible to get registered
now due to silly safety/emission rulings, but would be good collector cars.
These cars were never sold, and they are apparently cars that were built up
form spare parts in 1988.  As to VIN's, I haven't got the faintest idea.
There are a couple of the more run-of-the-mill cars that I know of as well
that have been getting driven with at least some regularity.

Any tips/insight would be appreciated.
