I know its probably worth the money, but for me it would have to be considerably cheaper to buy something that is probavly going to go bang a few weeks later (going on other superchargers in the past, I don't know yours at all)
I would like to have a go at the supercharger thing on a zs... but for the risk its not worth the strong money you are asking IMO
Good luck with sale though and I hope someone buys it for your sake
Also, still No subs so, technically you sgouldnt be selling on here...
