I would like to know about aluminum interior accents on the e39 M5. Is this aluminum the same look as the option for the e46 series car. If so, it looks pretty cheap, not altogether attractive. I would expect a much higher quality of finish on the more expensive car. Also, I have the e39 M5 brochure (on loan from my dealer) and it doesn't really explain the differences between the sportive and the exclusive interiors. Anyone with more experience care to comment? Thanks.
