Hi, I am very interested in buying a Copen. It is a 0.7 2005 model and looks gorgeous! I have been reading up on them and read that they require oil changes every 3000 miles, is this true? I commute 48 miles each day, how often does it require servicing & is this costly. I drive a Honda Type S GT at the moment so am hoping the running costs will be cheaper. Many thanks in anticipation.
