If I read the 2001 M5 spec sheet correctly, anything other the Sport interior is the "Heritage" Nappa, full leather. the extended leather with does not seem to be an alternative option. - Jim I've seen pics of M5's with the carmel interior where the lower dash, upper and lower door panels, and console appear all in carmel. Alternatively I've seen it with black in those areas with carmel accents. Anyone know why this would be the case-personally I like the black contrast with the carmel as opposed to everthing in the lighter color.
