Maybe a year or so ago, there were several for sale on this board. IIRC, prices were in the upper teens for cars with some mileage on them (hovering at or above 100k).
You would suspect that since the Weissach option was strictly a cosmetic option and not a performance enhancing option, the premium for these cars would be small. Based on last year's cars for sale, there was quite a bit of premium the sellers wanted for their cars.
In the spring of 2006, I called on a Weissach in my area with under 100k on the clock and in seemingly very nice shape. It was priced at $13k. It sold immediately.
I would suspect you could pay $1000 or more for this option over a comparable '80 SC IF the car is nice.
Good luck,
Jay
