Hi all, Just found this Japanese website, lots to look at with some good ideas, some you may recognise. You will need to use translation, which can be a bit of a laugh trying to work out what is meant. Give it a go http://yurusta.web.fc2.com/copen.html
It's a shame that any decent sites for the Copen are invariably Japanese. I suppose the car didn't sell in enough numbers in the UK to make selling accessories other than by Daihatsu worthwhile.
