Just found this great link to a PDF of a Copen spares parts list for the Japan Copen (L880K 659cc Turbo). http://mthill.com/copen/copen.pdf It's in Japanese, but the pictures & item numbers will lead you to the part number & the cost in Yen. So you can get an idea of the cost of the part here in the UK. Most parts will be the same for the UK Copen. However there are some differences. I believe the wiring loom is different, which is why the D-Sport ECU dosen't work properly on a UK spec car.
