1994=painted silver, clear coated
1995=clear anodized

I owned a 1994 E320 wagon and currently own a 1995 E320 sedan...I looked into this issue when the insurance company was debating totalling my wagon or not (see my gallery). I have found some 1995 wheels that have been refinished by one owner down the line with the clear coat, but from the factory ALL 1995s had the clear anodized appearance.
