If there still running as been a while since i spoke to them did a cossie 24v loom for them a few years back into an old wedge shape they can tell you all you need to know as iirc they used to work at tvr had a cerbera there the day i was and to be honest if it was on looks and sound i was in love till i looked underneath and it felt like i was looking at a cheep kit car!
