only one was ever made, in a shop in Germany near the border with The Netherlands, I know the company that made it, Zastrow was known for their extreme tuning components in the Eigthies.
I have recently locate a catalogue from them featuring this Countach and a Pantera they tuned in a similar way. Took 3 weeks to built a second car, but as far as I know they never made a second anyway ... don't know where this car now is, but I have never seen anything other than these photo's which were taken from the Zastrow catalogue.
