I have a 2004 c70 convertible. The wood (or plastic?) inserts on the steering wheel are beginning to show some cracking and roughness. Is there any way to repair this without the expense of a new wheel. Any suggestions would be appreciated. Also my 1990 245 headlights are showing some cloudiness. I was told that the kits on the market would not work because on Volvos the cloudiness begins on the inside of the lens. Is this true?
