I actually looked at your Car on ebay as I'm looking for another zed.
I'm sorry to say but you are going to struggle, I have had 2 jdm Zeds over the last 2 years, both were 53regs and both around 40k on the clock and massively struggled to get £5000 for them.
There is a massive stigma with import Zeds especially on ebay and people just won't touch them.
Also the mods may seem good to you but the won't be everyone's cup of tea.
I seriously was interested in your car, then I saw the interior and it put me straight off tan seats with a blue centre console :0
Straight away I start thinking about how much it's going to cost to put the interior back to stock
My advice would be to put it back to stock and sell for £5000-£5500 and the make up the rest of the money selling the parts on.
Good luck
