I just missed out on buying that Cerb when it was up for sale a few years ago.
I did ask about the mods at the time but didn't get any info back, the Spa dash and carbon interior looked interesting, would have liked to have seen it in the flesh.
This was my cerbera and my video. I sold it around 3 years ago. I know it might not be to everyone's likings but I made it my own and there was a reason for everything I did. I do miss the sound tho :-)
