There is your problem I recon was putting it in eBay, find the Aussie car enthusiasts sites for the UK and Europe, I'm sure someone will bite your arm off, they ain't cheap or easy to ship over as you probably know.
I was going to say, if your goon to loose money on shipping it back then don't do it, but it looks like you may actually make some more. So long as you ain't out of pocket.
