What are the best wiper blades to buy for the Copen as replacements? I've been to Halfords and Asda, neither stock any replacements for the Copen. I'm yet to try GSF and Euro Car Parts, when I get a chance. However looking on eBay there's some strange branded ones and different designs i.e aero etc. Anyone recommend some decent, reliable replacements please? Links would be very handy too - thanks.
