i bought http://www.ebay.co.uk/itm/Car-Cover...Make:Daihatsu|Model:Copen&hash=item416adf5b7e despite the description it's clearly not copen shaped, having said that it does more or less fit over and do the job - I tend to tuck it into the wheel arches and if it's going to be windy put a couple of bits of string around. I just didn't fancy paying a fortune for one that claimed to be a specific copen shape. it's not the best of the best quality but for the price it does the job.
