Thanks Hi Adam thanks for the links ill have a look im not to fussed about it been new or used i would be able to repair or paint a damaged one and this would probably keep the price down!
Just keep checking ebay for cars being broken. Trouble is the breaker will probably want you to buy the entire boot lid as well as the spoiler. To fit the spoiler holes need to be drilled. The breaker won't want a boot lid with holes in it to try & sell.
Contact these guys: http://www.mitchelldismantling.co.uk/new/pages/page_6.php They had a green Copen which had a spoiler for breaking. Chances are it's already gone, but worth a try.
